1 Summary

3 Heterotrophic marine bacteria play key roles in remineralizing organic matter

4 generated from primary production. However, far more is known about which 5 groups areFor dominant Peerthan about the Review cellular processes they Only perform in order to 6 become dominant. In the Southern Ocean, eukaryotic phytoplankton are the

7 dominant primary producers. In this study we used metagenomics and

8 metaproteomics to determine how the dominant bacterial and archaeal plankton

9 processed bloom material. We examined the microbial community composition in

10 fourteen metagenomes and found that the relative abundance of Flavobacteria

11 (dominated by Polaribacter ) was positively correlated with chlorophyll a

12 fluorescence, and the relative abundance of SAR11 was inversely correlated with

13 both fluorescence and Flavobacteria abundance. By performing metaproteomics on

14 the sample with the highest relative abundance of Flavobacteria (Newcomb Bay,

15 East Antarctica) we defined how Flavobacteria attach to and degrade diverse

16 complex organic material, how they make labile compounds available to

17 Alphaproteobacteria (especially SAR11) and Gammaproteobacteria , and how these

18 heterotrophic Proteobacteria target and utilize these nutrients. The presence of

19 methylotrophic proteins for archaea and bacteria also indicated the importance of

20 metabolic specialists. Overall, the study provides functional data for the microbial

21 mechanisms of nutrient cycling at the surface of the coastal Southern Ocean.

23 Introduction

24

25 Bacterioplankton populations in the world’s oceans are typically dominated by three

26 bacterial clades: Alphaproteobacteria , Gammaproteobacteria , and Bacteroidetes 27 (Glöckner Foret al. , 1999; Peer Kirchman, 2002; Review Kirchman et al. , 2003; Only O’Sullivan et al. , 2004; 28 Abell and Bowman, 2005a). They also dominate Southern Ocean bacterioplankton

29 populations in the austral summer (Abell and Bowman, 2005a,b; Murray and Grzymski,

30 2007; Jamieson et al. , 2012; Grzymski et al., 2012).

31 Flavobacteria , the major clade of Bacteroidetes in the marine environment, are

32 heterotrophs that target complex organic matter, and specialize in the degradation of

33 biopolymers (Pinhassi et al. , 1999; Cottrell and Kirchman. 2000; Kirchman, 2002; Abell

34 and Bowman, 2005a,b; González et al. , 2008; Teeling et al. , 2012). Flavobacteria target

35 high molecular weight compounds and tend to be abundant during phytoplankton blooms

36 (DeLong et al., 1993; Glöckner et al. , 1999; Pinhassi, 2004; West et al. , 2008; Teeling et

37 al. , 2012). Increased Flavobacteria abundance has been linked to enhanced primary

38 production (Brown and Bowman, 2001; Kirchman, 2002; HornerDevine et al. , 2003;

39 Abell and Bowman, 2005a; Murray and Grzymski, 2007), consistent with their role as

40 major mineralizers of organic matter (Cottrell and Kirchman, 2000). Flavobacteria are

41 especially important as the “first responders” to phytoplankton blooms, and by breaking

42 down complex organic matter by direct attachment and exoenzymatic attack of algal cells

43 and algalderived detrital particles (Kirchman, 2002; GómezPereira et al. , 2012; Teeling

44 et al. , 2012). Consistent with this, Flavobacteria tend to be abundant in the Southern

3

Wiley-Blackwell and Society for Applied Microbiology Page 4 of 165

45 Ocean where the waters are enriched in nutrients and phytoplankton (Abell and Bowman

46 2005a), particularly in summer (Grzymski et al., 2012; Williams et al., 2012).

47 Marine Alphaproteobacteria populations are dominated by the SAR11 and

48 Roseobacter clades, which favor labile substrates, including byproducts from the growth 49 of algae andFor Flavobacteria Peer (Mou et al.Review, 2008; Teeling et al. , 2012).Only Members of the 50 SAR11 clade are obligately planktonic, scavenge low concentrations of nutrients from

51 seawater (Morris et al. , 2002; Giovannoni et al. , 2005), and are most abundant where

52 phytoplankton biomass and primary production are low (Morris et al. , 2002; Sowell et

53 al. , 2009). Members of the Roseobacter clade of the Rhodobacterales are metabolically

54 diverse, targeting a wider range of substrates than SAR11 (WagnerDöbler and Biebl,

55 2006; Moran et al. , 2007), and are often found in close association with phytoplankton

56 (Pinhassi et al. , 2004; West et al. , 2008). SAR116 is a clade of Alphaproteobacteria that

57 has also been detected in a range of marine environments, and has been regarded as a

58 metabolic generalist (Oh et al. , 2010). Gammaproteobacteria also comprise a major

59 component of marine bacterioplankton, and are represented by phylogenetically diverse

60 clades. Marine members of Oceanospirillales and Alteromonadales include heterotrophs

61 with broad preferences, with coldadapted genera such as Colwellia ,

62 Pseudoalteromonas , Marinobacter and Psychromonas recorded in Southern Ocean

63 seawater and seaice off Antarctica (Bowman et al. , 1997; Piquet et al. , 2011). The

64 Oligotrophic Marine Gammaproteobacteria (OMG) group are physiologically diverse

65 marine heterotrophs that have been shown to be obligately oligotrophic when grown in

66 culture (Cho and Giovannoni, 2004).

67 In addition to these groups, Antarctic surface waters include putative

68 chemolithoautotrophs, notably sulfuroxidizing Gammaproteobacteria and ammonia

69 oxidizing Marine Group I Crenarchaeota (MGI), as major components of the

70 picoplankton (Murray and Grzymski, 2007; Gzymski et al. , 2012; Williams et al. , 2012). 71 Bacteria ofFor the gammaproteobacterial Peer Reviewsulfur oxidizer EOSA1 Only (GSOEOSA1) complex 72 have been reported in global mesopelagic waters (Swan et al., 2011) and

73 minimum zones (Walsh et al., 2009; Canfield et al., 2010), and their ecological role in

74 surface waters is yet to be determined (Grzymski et al. , 2012; Williams et al. , 2012).

75 MGI (also called Thaumarchaeota ) appear to play an important role performing ‘dark’

76 chemolithotrophic carbon fixation and nitrification in the bulk ocean (Konneke et al. ,

77 2005; Wuchter et al., 2006; Berg et al. , 2007), as well as in Antarctic surface waters in

78 winter (Grzymski et al. , 2012; Williams et al. , 2012).

79 In the North Sea, specific populations of Alphaproteobacteria ,

80 Gammaproteobacteria and Bacteroidetes have been shown to successively exploit

81 organic matter in response to diatom blooms (Teeling et al. , 2012). During the decline in

82 chlorophyll a levels that followed a bloom (marked by a rapid increase in chlorophyll a

83 levels from essentially zero to ~25 g L 1), the relative abundances of specific

84 Flavobacteria (Ulvibacter spp., Formosa spp., and Polaribacter spp.) and

85 Gammaproteobacteria (Reinekea spp. and SAR92 clade) were found to peak, while

86 specific groups of Alphaproteobacteria (SAR11 and Roseobacter clade) remained

87 comparatively constant (Teeling et al. , 2012).

88 The Southern Ocean is dominated by eukaryotic phytoplankton (rather than

89 Cyanobacteria ), and consists mainly of diatoms, dinoflagellates, and haptophytes (Wright

5

Wiley-Blackwell and Society for Applied Microbiology Page 6 of 165

90 et al. , 2010). Antarctic surface blooms occur as a result of release of nutrients

91 (particularly iron) upwelled over winter or through other nutrient incursions (Boyd and

92 Ellwood, 2010). For much of the Southern Ocean, surface concentrations of <0.3 – 0.4 g

93 L1 are typical, while higher chlorophyll concentrations (>1 g L 1) are associated with 94 the major SouthernFor Ocean Peer fronts, ice edgeReview blooms during seaice Only retreat in summer, and 95 coastal/shelf waters (Moore and Abbott, 2000). However to date, metagenome or

96 metaproteomebased studies of the bacterial and archaeal communities associated with

97 high chlorophyll a blooms in the Southern Ocean have not been reported.

98 In the current study we analyzed metagenomic data from 14 surface locations in the

99 Southern Ocean of East Antarctica, including coastal sites, to examine the comparative

100 diversity of community composition, and determine the abundance of Flavobacteria

101 relative to community composition and chlorophyll a levels. We then targeted for

102 metaproteomic analysis a sample from Newcomb Bay that was highly enriched in

103 Flavobacteria , in order to elucidate the processes by which these heterotrophs procured

104 and processed substrates, and contributed toward remineralization of organic matter. In

105 association with metaproteomic data for Alphaproteobacteria and Gammaproteobacteria

106 we gained insights into how coastal Antarctic bacterioplankton target substrates,

107 particularly those that could be linked to algal turnover, and what the major microbial

108 pathways were that were operating at the ocean surface.

110 Results and discussion

112 Phylogenetic diversity and influence of environmental factors on the community

113 composition of 14 Southern Ocean metagenomes 114 For Peer Review Only 115 To evaluate the representation of major taxonomic groups in the 14 Southern Ocean

116 metagenomes, the operational taxonomic unit (OTUs) from Genome Abundance and

117 Average Size (GAAS) analysis were manually sorted into Flavobacteria , SAR11,

118 Rhodobacterales , GSOEOSA1 complex, OMG, Oceanospirillales +Alteromonadales ,

119 SAR116, and MGI (Table 1, Fig. 1). OTUs pertaining to Oceanospirillales or

120 Alteromonadales were combined into one group due to the difficulty of resolving

121 relationships between members of these two Gammaproteobacteria orders (Williams et

122 al. , 2010). All the OTUs for phylum Bacteroidetes were members of the class

123 Flavobacteria .

124 OTUs with best matches to Bacteroidetes made up 3.2 to 50.4% of the metagenome

125 across the 14 samples (Table 1). The relative abundance of Flavobacteria was strongly

126 positively correlated with chlorophyll a fluorescence (Pearson's correlation coefficient r =

127 +0.81, p < 0.01) (Fig. 2). The wide range of chlorophyll a concentrations (0.14 to 12.1 g

128 L1) examined represent numerous stages of Southern Ocean algal blooms (Fig. 1 and 2).

129 By comparison, using DGGE 16S rRNA gene sequencing and fluorescent in situ

130 hybridization, no correlation was previously found between chlorophyll a fluorescence

131 and the abundance of planktonic Flavobacteria (size range 0.2 – 0.8 m) (Abell and

7

Wiley-Blackwell and Society for Applied Microbiology Page 8 of 165

132 Bowman, 2005a). However, notably in this study the chlorophyll a fluorescence in the

133 Southern Ocean samples only ranged from ~ 0.30 to 0.55 g L 1.

134 Our metagenome samples also resolved specific Flavobacteria OTUs, with

135 Polaribacter spp. and Psychroflexus torquis exhibiting significant correlations with 136 fluorescenceFor ( r = +0.82, Peer p < 0.01 and Reviewr = +0.69, p < 0.01, respectively). Only For all 14 137 samples, GAAS analysis showed Polaribacter spp. to be the dominant constituent of total

138 Bacteroidetes (67.8 – 97.6%). Other OTUs for Bacteroidetes that comprised at least

139 0.02% of metagenome data in at least one of the 14 samples included those with best

140 matches to Ps. torquis, Zunongwangia profunda, Flavobacterium spp ., Gramella forsetii

141 and the insect endosymbiont Ca. “Sulcia muelleri”. This is consistent with the significant

142 phylogenetic diversity for Bacteroidetes observed previously for Southern Ocean

143 Flavobacteria (Abell and Bowman, 2005a).

144 Members of the SAR11 clade (class Alphaproteobacteria ) were highly abundant

145 with OTUs ranging from 36.9 to 50.4% across the 14 samples (Table 1). The OTUs

146 represented Ca. “Pelagibacter ubique” HTCC1062, Ca. “P. ubique” HTCC1002, and Ca .

147 “Pelagibacter” sp. HTCC7211. The relative abundance of SAR11 was weakly inversely

148 correlated with fluorescence ( r = 0.56, p < 0.05), but strongly inversely correlated with

149 the relative abundance of Flavobacteria (r = 0.80, p < 0.01) (Fig. 2). A negative

150 correlation between SAR11 and phytoplankton blooms was previously observed in

151 Antarctic Peninsula and Kerguelen Island waters (Ghiglioni and Murray, 2012).

152 OTUs with the best matches to order Rhodobacterales (class Alphaproteobacteria )

153 comprised 0.4 to 7.7% of relative abundances in the metagenome (Table 1), including

154 OTUs with best matches to Roseobacter denitrificans, Ruegeria sp. TM1040, and the

8

Wiley-Blackwell and Society for Applied Microbiology Page 9 of 165

155 proteorhodopsincontaining Roseobacter clade strain HTCC2255. However, no

156 relationship was found between Rhodobacterales and fluorescence, despite a reported

157 association of certain members of the Roseobacter clade with phytoplankton (Buchan et

158 al. , 2005; Moran et al. , 2007). 159 The SAR116For clade Peer (class Alphaproteobacteria Review) was represented Only by a single OTU 160 with the best match to Ca. “Puniceispirillum marinum” IMCC1322 (Oh et al. , 2010),

161 which made up < 0.2% of the metagenome data (Table 1). Relative abundances of

162 SAR116 and Oceanospirillales +Alteromonadales (class Gammaproteobacteria ) were

163 strongly correlated ( r = +0.86, p < 0.01). This was unrelated to fluorescence, water

164 column depth, or distance from the coastline. The Oceanospirillales +Alteromonadales

165 group was represented in the metagenome by OTUs with best matches to the genera

166 Colwellia, Marinobacter, Marinomonas, Neptuniibacter, Pseudoalteromonas,

167 Psychromonas, Saccharophagus, and Shewanella . When combined, the

168 Oceanospirillales +Alteromonadales group made up 0.08 to 2.2% of the total

169 metagenome data (Table 1). A strong correlation was also observed between the relative

170 abundances of OMG (represented by uncultivated strain NOR53) and

171 Alteromonadales +Oceanospirillales (r = +0.89, p < 0.01), and between OMG and

172 SAR116 ( r = +0.92, p < 0.01).

173 The detection of GSOEOSA1 (order Thiotrichales , class Gammaproteobacteria;

174 Williams et al. , 2010) is indicative of the presence of freeliving pelagic members of this

175 complex, including the gammaproteobacterial SUP05/Arctic96BD19 clade (Walsh et al. ,

176 2009; Swan et al. , 2011). The GSOEOSA1 OTUs had best matches to Ca. “Ruthia

177 magnifica” and Ca. “Vesicomyosocius okutanii”, endosymbionts of deepsea bivalves

9

Wiley-Blackwell and Society for Applied Microbiology Page 10 of 165

178 (Newton et al. , 2007; Kuwahara et al. , 2011), and comprised up to 7.9% of the

179 metagenome across the 14 samples (Table 1). It is likely these OTUs attracted sequences

180 originating from planktonic GSOEOSA1 bacteria. Ca. “R. magnifica” and Ca. “V.

181 okutanii” are chemolithoautotrophs (Newton et al. , 2007; Kuwahara et al. , 2011), 182 although a Forrecently isolated Peer member ofReview the SUP05/Arctic96BD19 Only clade from the North 183 Pacific gyre was inferred to be an aerobic, sulfuroxidizing heterotroph (Marshall and

184 Morris, 2012). Other members of Thiotrichales also found matches in the NB

185 metagenome (e.g., Thiomicrospira crunogena ). Our study found no correlation between

186 relative abundance of GSOEOSA1 OTUs and water column depth, meaning that their

187 presence in surface waters is unlikely to be due solely to deep mixing.

188 MGI had the closest genomic match to the ammoniaoxidizing species Ca.

189 “Nitrosopumilus maritimus” (Table 1). MGI showed the greatest range of contributions

190 across the 14 metagenomic samples, with OTUs with best matches to Ca. “N. maritimus”

191 making up to 10.2% of the total metagenome (Table 1). After logarithmic transformation,

192 the relative abundance of MGI was found to be inversely correlated with both the depth

193 of the water column and the distance from the Antarctic landmass ( r = 0.80, p < 0.01 and

194 r = 0.78, p < 0.01, respectively).

197 Newcomb Bay metaproteogenomic overview

198

199 The Newcomb Bay metagenome (NB metagenome) and Newcomb Bay metaproteome

200 (NB metaproteome) were defined by matches to Bacteria, Archaea and viruses (see

10

Wiley-Blackwell and Society for Applied Microbiology Page 11 of 165

201 Experimental procedures) enabling the data to be directly compared. The Newcomb Bay

202 sample (#235; Fig. 1) was chosen because it contained the highest proportion of

203 Flavobacteria (Table 1, Fig. 2 and 3). A total of 548 proteins were identified (Table S1),

204 of which 446 proteins were identified using the AntComb database, 102 using NR, and 5 205 were commonFor to both. Peer A list of all proteins Review detected in the NB Only metaproteome that are 206 discussed in the main text is provided in Table 2. Of the 102 proteins identified using NR,

207 43 matched eukaryotic taxa, with 21 of these matching proteins of the diatom genus

208 Thalassiosira . Overall, protein sequence data was far better represented in fosmids and

209 shotgun metagenomic data than in microbial genomes contained in NR. Nevertheless, it

210 was only through NR that proteins pertaining to methanogenic Euryarchaeota were

211 detected (see Methylotrophy below); this clade was not detected in the metagenome.

212 Counts of unique peptides and assigned spectra are shown in Table S2.

213 A total of 472 proteins had highest sequence identity to bacterial proteins, 12 to

214 archaeal proteins, 61 to eukaryotic proteins, and three to virus (phage) proteins. Within

215 the bacterial subset, the majority had the best match (highest sequence identity) to

216 proteins from members of the Bacteroidetes (221), Gammaproteobacteria (174), and

217 Alphaproteobacteria (69). Protein matches to the Bacteroidetes clade were mainly to

218 Flavobacteria (216). Within the Gammaproteobacteria , most of the proteins had the best

219 match to Oceanospirillales +Alteromonadales (107), OMG (27), Pseudomonadales (17),

220 and GSOEOSA1 (13). For the Alphaproteobacteria , nearly half (34) of the matches had

221 highest identity to proteins from the Rhodobacterales; other proteins had best matches to

222 members of the oligotrophic SAR11 cluster (including Ca. “Pelagibacter ubique”; 23),

223 Rhizobiales (6), and uncultivated SAR116 cluster (5). Proteins from Alphaproteobacteria

11

Wiley-Blackwell and Society for Applied Microbiology Page 12 of 165

224 were mostly from ATPbinding cassette (ABC) transporters or other active transport

225 systems that involve solute binding (48) (see Uptake of labile solutes below).

226 Bacteroidetes and SAR11 comprised 50.5% and 36.9% of the NB metagenome, and

227 45.4 and 4.7% of the NB metaproteome, respectively (Table 1, Fig. 3). In the NB 228 metaproteome,For all but Peerfive of the 221 ReviewBacteroidetes proteins hadOnly best matches to 229 Flavobacteria , and 183 had best matches to Polaribacter spp. (Table S1), consistent with

230 their dominance in the metaproteome sampled from the decay phase of a North Sea algal

231 bloom (Teeling et al. , 2012). The much higher relative abundance of protein matches to

232 Flavobacteria compared to SAR11 likely reflects their particular trophic strategies.

233 Marine Flavobacteria are copiotrophs that specialize in the exploitation of organic matter

234 that results from algal blooms (Kirchman, 2002; GómezPereira et al. , 2012; Teeling et

235 al. , 2012), and therefore exhibit increased protein synthesis levels to maximize capture

236 and processing of available complex substrates. SAR11 are nonmotile oligotrophs that

237 are reliant on dilute concentrations of labile nutrients (Giovannoni et al ., 2005), and the

238 synthesis of cellular proteins by SAR11 is likely to be relatively unresponsive to

239 increases in nutrient load. Also, whereas diverse Flavobacteria target multiple polymeric

240 substrates that require extracytoplasmic processing prior to import, SAR11 expresses

241 extracytoplasmic proteins that target labile solutes (such as amino acids) which are

242 processed cytoplasmically (see Uptake of labile solutes , below). High expression levels

243 of these extracytoplasmic proteins are needed to enhance the frequency of substrate

244 binding and initial degradation ( Flavobacteria ) or solute capture (SAR11), whereas

245 subsequent conversion of the imported substrates requires a relatively lower level of

246 expression of cytoplasmic (Sowell et al ., 2009).

12

Wiley-Blackwell and Society for Applied Microbiology Page 13 of 165

247 Similar to SAR11, some other microbial groups exhibited large differences between

248 their representation in the NB metagenome and NB metaproteome (Fig. 3). For example,

249 Oceanospirillales +Alteromonadales represented 0.6% of the NB metagenome but 22.2%

250 of the NB metaproteome, and Rhodobacterales represented 0.23% and 7%, respectively. 251 Certain microorganismsFor Peer that comprise Review numerically minor components Only of a community 252 have been shown to be major contributors to nutrient cycling (Musat et al. , 2008). The

253 NB metaproteome includes proteins consistent with chemoorganotrophic growth in

254 Antarctic surface waters (see Biopolymer utilization and Uptake of labile solutes , below).

255 For Oceanospirillales +Alteromonadales , the detection of Krebs cycle and

256 gluconeogenesis enzymes (Table S1) could indicate that a higher proportion of carbon is

257 being diverted to storage rather than to growth. By contrast, the central metabolic

258 pathways evident for Flavobacteria indicate both biomass production and carbon storage

259 pathways are active (Table S1).

260 GSOEOSA1 represented 1.7% of the NB metagenome and 2.7% of the NB

261 metaproteome, but the identities of the detected proteins offered few clues as to the

262 ecophysiology of this group at the surface, aside from expression of housekeeping genes

263 (Table S1). In an environment dominated by algaldriven primary production and

264 exposed to aroundtheclock solar illumination, the NB metaproteome shows no evidence

265 for lightindependent (‘dark’) carbon fixation at the surface by chemolithoautotrophic

266 bacteria or archaea.

267 MGI proteins were not detected in the NB metaproteome despite MGI having a

268 relative NB metagenome abundance of 4.4% (Table 1). In a study of Southern Ocean

269 surface waters near the Antarctic Peninsula, MGI proteins were not detected in the

13

Wiley-Blackwell and Society for Applied Microbiology Page 14 of 165

270 summer metaproteome, whereas MGI proteins were abundant in winter (Williams et al. ,

271 2012). The presence of MGI in surface waters in the NB metagenome (Table 1) may be

272 due to the upwelling of cells from bottom sediments of the relatively shallow waters of

273 Newcomb Bay. MGI have been detected at the surface of the Arctic Ocean, although no 274 seasonal patternFor was identifiedPeer (Galand Review et al ., 2009), and numbers Only were found to be 275 depressed by riverine input in coastal Arctic waters (Galand et al ., 2008). MGI were not

276 detected in the picoplankton metagenome from the Southern Ocean near the Antarctic

277 Peninsula (Grzymski et al ., 2012), although they were a dominant component in the

278 winter where they made up 12% of the metagenome and 30% of the metaproteome

279 (Grzymski et al ., 2012; Williams et al ., 2012). MGI have been detected in benthic

280 sediments along the Antarctic continental shelf (Bowman and McCuaig, 2003). The

281 current data are consistent with MGI being adventitiously brought to the surface of the

282 Southern Ocean from local sediment or deeper waters (and hence are less likely to reach

283 the surface in water columns of increasing depth), but have minimal metabolic activity at

284 the surface in the austral summer. This may be due to factors that suppress growth and

285 activity of MGI, such as extensive illumination (photoinhibition; Kalanetra et al., 2009;

286 Merbt et al. , 2011).

287 Protein matches to eukaryotic phytoplankton were predominantly from various

288 diatom species (45/61), principally Thalassiosira spp. (34; Table S1). Macroplankton

289 would be expected to be captured by the 20 m prefilter or 3 m filter (see Materials and

290 Methods ). The eukaryotic proteins present on the 0.1 m filters are therefore likely to

291 originate from phytoplankton turnover, or from unicellular microalgae such as

292 Ostreococcus tauri . The presence of diatom proteins is consistent with the association of

14

Wiley-Blackwell and Society for Applied Microbiology Page 15 of 165

293 Flavobacteria with diatoms (Pinhassi et al. , 2004; Fandino et al. , 2005; Grossart et al. ,

294 2005; Piquet et al. , 2011; Teeling et al. , 2012).

299 Biopolymer utilization: Predicted outer membrane proteins were a major component of

300 the NB metaproteome, especially components of TonBdependent transporter (TBDT)

301 systems, with receptors representing 6.6% of the NB metaproteome and 1.8% of the NB

302 metagenome (the highest abundance of all identified genes in the dataset) (Table 3).

303 TBDTs are outer membrane transporters involved in the uptake of macromolecules that

304 are too large to diffuse via porins. TBDTs that target biopolymers (e.g., polysaccharides,

305 proteins, proteoglycan) act in concert with outer membrane substratebinding proteins

306 and degradative enzymes (e.g., glycosyl , peptidases) to facilitate the use of

307 these complex substrates (Reeves et al. , 1997; Gilbert, 2008).The majority of TBDTs in

308 the NB metaproteome had the best matches to Flavobacteria , although some were to the

309 OMG (Tables 3 and S1); similar transporter expression profiles to these have been

310 described for the North Sea for Flavobacteria and OMG (Teeling et al. , 2012). Other

311 marine metaproteomic studies have reported TBDT components to represent 7% (before)

312 and 13% (during) a diatomassociated bacterioplankton bloom in North Sea surface

313 waters (Teeling et al. , 2012), and to be very abundant in nutrientenriched coastal marine

314 systems (Morris et al. , 2010; Teeling et al. , 2012). TBDT proteins most closely related to

315 Bacteroidetes and Gammaproteobacteria were the dominant membrane protein class in

15

Wiley-Blackwell and Society for Applied Microbiology Page 16 of 165

316 coastal seawater of the South Atlantic Ocean (Morris et al. , 2010) and of the Southern

317 Ocean off the Antarctic Peninsula in the austral summer (Williams et al. , 2012).

318 Several secreted glycosyl hydrolases, including betaglucanases, were detected in the

319 NB metaproteome (Tables 3 and S1), which indicates that the Newcomb Bay population 320 of FlavobacteriaFor were Peertargeting storage Review polysaccharides from Only algae as substrates. Also 321 detected were predicted secreted and cytoplasmic with best matches to

322 Flavobacteria (Tables 3 and S1). These findings are consistent with Polaribacter sp.

323 MED152 encoding large numbers of genes encoding peptidases, glycosyl hydrolases, and

324 TBDTs (González et al. , 2008), and Flavobacteria showing increased glycosyl

325 and activities associated with the utilization of carbohydrates and

326 proteins in seawater microcosm experiments (Pinhassi et al. , 2004). In addition to

327 targeting polysaccharides and proteins, predicted secreted enzymes with lipolytic or

328 phosphohydrolase domains (Table S1) were identified, indicating that a diversity of non

329 labile substrates were being utilized. Gliding motility proteins were detected (Tables 3

330 and S1), which allow exploration of solid surfaces by Flavobacteria (McBride, 2001).

331 Also detected were predicted secreted flavobacterial proteins with domains associated

332 with proteinprotein interactions (TPR, PKD) or cell adhesion (fasciclin) (Table S1);

333 these hypothetical proteins might play roles in the adhesion of Flavobacteria to algal

334 surfaces or detrital particles (Woyke et al. , 2009; GómezPereira et al. , 2012). Overall,

335 the findings indicate that TBDT systems, biopolymerdegrading enzymes, and proteins

336 involved in attachment and colonization of cell and detrital surfaces are functionally very

337 important for the growth of Flavobacteria associated with phytoplankton in Newcomb

338 Bay, which is consistent with their inferred lifestyle in other cold and temperate marine

16

Wiley-Blackwell and Society for Applied Microbiology Page 17 of 165

339 waters (e.g ., Pinhassi et al. , 1999; Cottrell and Kirchman. 2000; Kirchman, 2002; Abell

340 and Bowman, 2005a,b; González et al. , 2008; Morris et al. , 2010; Williams et al. , 2012).

341 Glycolysis enzymes were detected with best matches to Flavobacteria and

342 Gammaproteobacteria (Table S1), suggesting that the degradation of complex 343 carbohydratesFor by the FlavobacteriaPeer increasesReview the availability Only and utilization of less 344 complex carbohydrates by other heterotrophs, as has been reported for bacterioplankton

345 communities in the North Sea (Teeling et al. , 2012). Based on catabolic

346 enzymes with closest matches to flavobacterial proteins (Table S1), glutamate and

347 aspartate appear to be the preferred amino acids for the Newcomb Bay Flavobacteria , as

348 found for the human oral commensal Bacteroidetes Porphyromonas gingivalis

349 (Takahashi et al. , 2000). Both amino acids can be converted into Krebs cycle

350 intermediates: glutamate is deaminated to 2oxoglutarate by glutamate dehydrogenase,

351 and decarboxylated and activated to succinylCoA by 2oxoglutarate , and

352 aspartate is transaminated to 2oxoglutarate and glutamate by aspartate aminotransferase.

353 All three enzymes were detected in the metaproteome. Aspartate can also be deaminated

354 to fumarate, and then oxidized to acetate, or reduced to butyrate via succinylCoA

355 (Takahashi et al. , 2000). The detection of proteins pertaining to both pathways (malate

356 dehydrogenase, butyrylCoA dehydrogenase) indicates that both oxidative and reductive

357 degradation was occurring, enabling redox balance to be maintained inside the cell.

358 Acetate generated from amino acid degradation by Flavobacteria is one potential source

359 of this substrate for SAR11; a predicted acetate/sodium symporter was detected for

360 SAR11 (Table S1).

17

Wiley-Blackwell and Society for Applied Microbiology Page 18 of 165

361 Although only one glutamine synthetase protein was detected in the metaproteome,

362 the gene for glutamine synthetase was the second most abundant type of gene identified

363 in the Newcomb Bay metagenome (Table 3). The deamination steps of amino acid

364 catabolism liberate ammonia, which implies, by virtue of their abundance, that the 365 FlavobacteriaFor perform Peer a potentially importantReview function in nitrog Onlyen cycling in the 366 Southern Ocean by generating ammonia from organic . Certain marine

367 Flavobacteria have been shown to be unable to utilize ammonia as a nitrogen source

368 (Suzuki et al. , 2001), allowing this byproduct to be scavenged by other marine

369 microorganisms.

370

371 Uptake of labile solutes: ABC transporters were detected in the NB metaproteome for

372 multiple groups of Proteobacteria , including SAR11, Rhodobacterales , SAR116, and

373 various Gammaproteobacteria . Those with best matches to SAR11 had predicted

374 specificities for amino acids (especially branchedchain amino acids), taurine,

375 polyamines, and carbohydrates (including glycerol3phosphate), although the majority

376 of the latter showed the best matches to Rhodobacterales (Tables 3 and S1). The ability

377 of Rhodobacterales to target common constituents of algal exudates such as taurine,

378 polyamines, and glycolate, and form commensal associations with phytoplankton

379 (Buchan et al. , 2005), is consistent with growth in Newcomb Bay using a broad range of

380 substrates (Brinkhoff et al. , 2008). This is in contrast to Polaribacter , which cannot

381 utilize these algal exudates (Gonzalez et al. , 2008). As a metabolite released by

382 phytoplankton during photorespiration, glycolate could be an important substrate for

18

Wiley-Blackwell and Society for Applied Microbiology Page 19 of 165

383 marine heterotrophic bacteria, particularly during the long period of solar radiation that

384 occurs at the surface of the Southern Ocean during the austral summer.

385 Other identified solutebinding proteins belong to secondary uptake systems with

386 best matches to SAR11: tripartite ATPindependent periplasmic (TRAP) transporters and 387 tripartite tricarboxylateFor Peer transporters (TTT)Review (Tables 3 and S1). Only In Gram negative bacteria, 388 the solutebinding proteins accumulate in the periplasm and capture solutes that are

389 subsequently imported into the cytoplasm (Forward et al. , 1997; Winnen et al ., 2003).

390 These active uptake systems scavenge low concentrations of nutrients present in the

391 environment, and have been identified as abundant components of marine

392 metaproteomes, particularly for members of the Alphaproteobacteria (Sowell et al. ,

393 2009, 2011; Morris et al ., 2010; Williams et al. , 2012; Teeling et al. , 2012).

394 The NB metaproteome data indicates that at the time of sampling in Newcomb Bay

395 SAR116 targeted similar substrates to SAR11 using ABC and TRAP transporters (amino

396 acids, taurine, dicarboxylates). The NB metaproteome data also indicate that certain

397 members of Oceanospirillales +Alteromonadales use ABC transporters to target different

398 labile substrates to SAR11 and SAR116, with a preference for carbohydrates (including

399 glycerol3phosphate) (Tables 3 and S1). In addition, two ABC transporter proteins for

400 amino acids had best matches to Ant4D3 (Tables 3 and S1). Ant4D3 is an uncultured

401 Gammaproteobacteria lineage that was identified from fosmid data (Grzymski et al. ,

402 2006) and has been reported to be abundant in Antarctic Peninsula coastal waters (up to

403 10% of bacterioplankton) and actively incorporate amino acids (Grzymski et al. , 2006;

404 Straza et al. , 2010). Our data indicate that Ant4D3 is distributed, and likely active, in

405 Antarctic waters well beyond the Antarctic Peninsula.

408 Responses to light and oxidative stress: The NB metaproteome included two

409 proteorhodopsins (Tables 3 and S1), photoactive cell membrane proteins from bacteria 410 and archaeaFor (Béjà et al.,Peer 2000, 2001; DeLongReview and Béjà, 2010). Only These had highest 411 sequence identities to proteorhodopsins from Polaribacter sp. MED52 and OMG. Both

412 had leucine at position 105 in the proteorhodopsin sequence, indicating spectral tuning to

413 an absorption maxima near 530nm (green light), consistent with responses to illumination

414 at or near the ocean surface (GómezConsarnau et al. , 2007). The ability of

415 proteorhodopsin to function as a lightdriven proton pump for the generation of energy

416 for cell growth and maintenance (GómezConsarnau et al. , 2007; Kimura et al. , 2011)

417 and enhanced utilization of organic matter for biosynthesis (Gonzalez et al. , 2008) should

418 enable the exploitation of light for photoheterotrophic growth during the Antarctic austral

419 summer.

420 High solar irradiance in aerobic surface waters can lead to oxidative stress, and

421 proteins involved in protection against damage caused by reactive oxygen species

422 (superoxide dismutase, peroxidase, thioredoxin, thioredoxin reductase,

423 alkylhydroperoxidase) were abundant, with most having best matches to Flavobacteria

424 (Table S1). The requirement for these enzymes may be exacerbated by the affinity that

425 Flavobacteria have for phytoplanktonderived matter, which would be most abundant at

426 the ocean surface, and possibly also by exposure to regions of reduced salinity resulting

427 from the input of glacial and seaice meltwater.

429 Methylotrophy: Twelve proteins in the NB metaproteome were assigned to the

430 methanogenic archaeon Methanococcoides burtonii . These proteins were only able to be

431 identified because the complete genome of M. burtonii was available in the NR database.

432 In view of the absence of this taxon in the NB metagenome data, and the fact that there 433 were no peptideFor matches Peer in the AntComb Review database (Table S1 Only and S2), our data suggests 434 that this methanogen played only a minor role in the picoplankton community of

435 Newcomb Bay. Nevertheless, the presence of M. burtonii in surface waters of the

436 Southern Ocean is consistent with the identification of a methanogen affiliated with

437 Methanococcoides methylutens (a species that is phylogenetically closely related to M.

438 burtonii ; Thomas and Cavicchioli, 1998) in surface waters of the eastern Pacific Ocean,

439 which was proposed to survive in anoxic microzones within detritus (Cynar and

440 Yayanos, 1991). M. burtonii is an anaerobic obligate methylotroph that was originally

441 isolated from anoxic sediments in a marinederived Antarctic lake (Franzmann et al. ,

442 1992). M. burtonii proteins detected from the Newcomb Bay sample include those

443 directly involved in the dismutation of the methylated substrates methanol and

444 trimethylamine to methane and CO 2 (Table S1). Methanol and trimethylamine (substrates

445 utilized by M. burtonii and M. methylutens ) have been implicated as important substrates

446 for bacterioplankton (Giovannoni et al., 2008; Chen et al. , 2011; Sowell et al. , 2011). In

447 addition to the methyltransferases assigned to M. burtonii , others (including a putative

448 trimethylamine methyltransferase) had best matches to OMG (Tables 3 and S1),

449 indicating possible methylotrophic behavior by this group of bacteria in Newcomb Bay.

450 The presence of these methyltransferases for methanogens and aerobic bacteria indicates

21

Wiley-Blackwell and Society for Applied Microbiology Page 22 of 165

451 that sufficient levels of substrate are present, presumably in particles, to permit both

452 anaerobic and aerobic methylotrophic growth.

453

454 455 ConclusionsFor Peer Review Only 456

457 The metagenomic survey of surface waters from 14 Southern Ocean sites confirms the

458 dominance of Flavobacteria , Alphaproteobacteria , and Gammaproteobacteria in these

459 waters, alongside groups that are not characteristic of picoplankton in more temperate

460 parts of the World Ocean, such as MGI and GSOEOSA1. The abundance of

461 Flavobacteria positively correlated with chlorophyll a fluorescence, confirming a

462 relationship between primary productivity and Flavobacteria in polar waters.

463 Metaproteomic analysis of the Newcomb Bay site determined that Flavobacteria actively

464 deployed systems for the binding and exploitation of polymeric substrates, including

465 carbohydrates, polypeptides, and lipids; the dominant biopolymers within aggregates that

466 are derived from marine detritus (Alldredge, 1979). Algalderived polymers are utilized

467 by these heterotrophs, which in turn release simpler compounds (simple sugars, acetate,

468 ammonia) as byproducts that can be exploited by other microorganisms. The current

469 metaproteomic data corroborates the view that scavenging of nutrients by highaffinity

470 uptake systems is a determining factor in microbial competition and survival, even in

471 relatively nutrient replete coastal ecosystems (Sowell et al. , 2011; Teeling et al. , 2012).

472 Having established the functional properties of these planktonic communities, we are

473 now in a position to analyze larger size fractions and examine the taxonomic and

22

Wiley-Blackwell and Society for Applied Microbiology Page 23 of 165

474 functional distinctions of particleassociated and larger cell size communities associated

475 with algal blooms.

480 Sample collection and GAAS analysis

481

482 Seawater samples from 14 sites in the Southern Ocean (Table 1, Fig. 1), representing

483 three East Antarctica sampling seasons, and including coastal samples, were collected

484 from surface waters (depths of 12 m). The microbial biomass from 200 L (samples from

485 January 2007) or 500 L (samples from December 2007, January 2008, October 2008 and

486 December 2008) of seawater was collected by sequential size fractionation through a 20

487 m prefilter on to filters (3.0, 0.8 and 0.1 m poresized, 293 mm polyethersulfone

488 membrane filters), and filters placed into tubes containing storage buffer and

489 cryogenically preserved as described previously (Rusch et al., 2007; Ng et al. , 2010). In

490 this study, we present data for microorganisms that passed through the 0.8 µm filter and

491 were captured on the 0.1 µm filter. The sampling site characteristics for the Newcomb

492 Bay, sample (#235; Table 1, Fig. 1) were: 400 m from shore, water column depth 60 m

493 deep, midday, clear skies, water temperature 0.65°C, air temperature 0.8°C, salinity

494 33.9%, fluorescence 8.6 g L 1, air pressure 737.7 mmHg.

495 To determine the OTU composition and relative abundances within each seawater

496 sample of archaea, bacteria and viruses (excluding eukaryotes), a database of genomes

23

Wiley-Blackwell and Society for Applied Microbiology Page 24 of 165

497 was prepared from the RefSeq microbial (bacteria and archaea) and viral databases

498 (release 41, retrieved May 31 2010 from ftp://ftp.ncbi.nih.gov/refseq/release/). Sequences

499 with the words “shotgun”, “contig”, “partial”, “end” or “part” in their headers were

500 excluded (after Angly et al ., 2009). The metagenomic reads were compared to this 501 database usingFor BLASTN Peer with default Reviewparameters (Evalue threshold Only 0.001). To minimize 502 spurious OTU identifications and increase the accuracy of relative abundance estimates, a

503 core set of most probable OTUs was identified with minspec which was developed based

504 on the approach used in minpath to reconstruct biochemical pathways (Ye and Doak,

505 2009; Wilkins et al. , unpublished results), and hits to OTUs not in the set were excluded

506 from the BLAST outputs. To determine relative abundances of OTUs, the perl script

507 GAAS (Angly et al. , 2009) was run on the BLAST output from each sample. To take into

508 account reads which did not yield highquality hits to any sequence in the reference

509 database, GAAS relative abundance estimates were scaled by the effective BLAST hit

510 rate for each sample. Because the RefSeq database did not include genomes for several

511 organisms that are likely to be abundant in Antarctic waters (Williams et al. , 2012), the

512 following genomic scaffolds were retrieved from Genbank and an additional database

513 constructed (Genbank accessions given in brackets): Neptuniibacter caesariensis MED92

514 (CH724125.1); Polaribacter irgensii 23P (NZ_CH724148.1); Polaribacter sp. MED152

515 (AANA01000001.1 and AANA01000002.1); Psychroflexus torquis ATCC 700755

516 (CH959305.1); Ca. “Pelagibacter ubique” HTCC1002 (NZ_CH724130.1); Ca.

517 “Pelagibacter” sp. HTCC7211 (DS995298.1); alpha proteobacterium HTCC2255

518 (DS022282.1). BLAST comparisons and relative abundance estimations were performed

519 as above. While GAAS was designed for use only with complete reference genomes

24

Wiley-Blackwell and Society for Applied Microbiology Page 25 of 165

520 (Angly et al., 2009), the nearcompleteness of the genomic scaffolds selected enhances

521 the reliability of the analysis using the additional genomic data. Only OTUs that had a

522 relative abundance of 0.02% or more in at least one of the samples were included. These

523 values correspond to relative abundances of cells within the samples. Data presented in 524 Table 1 wereFor subjected Peer to statistical analysisReview (Pearson Only Moment Correlation, 525 ANOVA regression analysis for statistical significance). The relative abundances of

526 individual groups (including logarithmically transformed data) were compared to one

527 another, as well as to known environmental parameters (collection date, latitude,

528 longitude, chlorophyll a fluorescence, distance from Antarctic landmass, and water

529 column depth).

530 For the Newcomb Bay site (#235; 0.1 m fraction; Table 1, Fig. 1), the SEED

531 database of translated genes was obtained from

532 ftp://ftp.theseed.org/subsystems/subsystems.complex on May 9 2012 and a BLAST

533 database constructed. Reads from the NB metagenome were compared to the SEED

534 database using blastx, with default parameters except for an Evalue threshold of 0.001.

535 The method of Coleman and Chisholm (2010) was adapted to count the number of hits to

536 genes in the database. For each read, if the top three hits (or all hits if fewer than three)

537 belonged to the same gene family with bit scores > 40, the read was annotated with that

538 gene. If there was a large (> 30) difference in bit score between hits, the lower scoring

539 hits were discarded. All identified genes with a relative abundance of at least 0.2% were

540 reported (Table 3; a complete list is in Table S3).

25

Wiley-Blackwell and Society for Applied Microbiology Page 26 of 165

543

544 Metaproteomic analysis of biomass extracted from the Newcomb Bay 0.1 m filter was

545 performed as described previously (Ng et al., 2010; Williams et al. , 2012). In brief, 20

546 mL lysis buffer contained 10 mM TrisEDTA (pH 8.0; Univar, Sydney, Australia), 20 L 547 of proteaseFor inhibitor cocktailPeer VI (Calbiochem, Review San Diego, CA), Only 0.1% sodium dodecyl 548 sulfate (Univar) and 1 mM dithiothreitol (SigmaAldrich, Sydney, Australia). The only

549 methodological variation was the use of five rounds of sonication at 40 s intervals, 0.5

550 pulse on/0.5 pulse off, 20% amplitude, and a 3 kDa rather than 5 kDa Amicon filter unit.

551 Proteins were identified using two databases which contained sequences from archaea,

552 bacteria, viruses and eukaryotes: NR and AntComb (a customized Antarctic

553 metaproteome sequence database constructed from fosmid libraries and Southern Ocean

554 metagenome data) (Williams et al. , 2012). AntComb was constructed from: fosmid

555 libraries (IMG Acc: 2008193000, 2008193001, 2012990003, 2040502005 and

556 2040502004), individual marine microbial genomes (RefSeq Project ID: 202, 58903,

561 SRX024736 and SRX024800). MS/MS data analysis and validation of protein

562 identifications were performed as previously described (Ng et al ., 2010) except that the

563 databases used were NR and AntComb (Williams et al. , 2012). Mascot searches with a

564 false discovery rate 45% were rejected. All other Mascot results were combined and

565 validated using a MudPit analysis in Scaffold 3.0 (Proteome Software Inc., Portland, OR,

26

Wiley-Blackwell and Society for Applied Microbiology Page 27 of 165

566 USA) using the following parameters: minimal probability of peptide identification, 95%;

567 minimal probability of protein identification, 99%. Protein matches were only accepted if

568 they were identified by a minimum of two unique peptides. All proteins were manually

569 annotated using BLASTP, and the protein that showed the highest sequence identity was 570 recorded, includingFor the Peer organism name Review (Table S1). The NB metaproteomeOnly was defined 571 by all proteins that were detected with matches to bacteria, archaea and viruses

572 (excluding eukaryotes).
