Genomic Insight Into the Host–Endosymbiont Relationship of Endozoicomonas Montiporae CL-33T with Its Coral Host

Although, it is likely to be a core member of coral microbiota, little is known about its ecological roles. To decipher potential interactions between bacteria and their coral hosts, we sequenced and investigated the first culturable endozoicomonal bacterium from coral, the E. montiporae CL-33T.

The strain was oxidase- and catalase-positive, metabolized a variety of carboxylic acids and sugars and produced lipase. Cells had an absolute requirement for artificial sea water, which could not be replaced by NaCl. A large in vivo absorption band at 870 nm indicated production of bacteriochlorophyll a. The predominant fatty acids of this organism were 16 : 0 and 18 : 1v7c, with 3-OH 10 : 0, 16 : 1v7c and 18 : 0 in lower amounts. The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine. Ubiquinone 10 was produced. The DNA G+C content was 67 mol%. 16S rRNA gene sequence comparisons indicated that the isolate represents a member of the Roseobacter clade within the a-Proteobacteria. The organism showed no particular relationship to any members of this clade but clustered on the periphery of the genera Jannaschia, Octadecabacter and ‘Marinosulfonomonas’ and the species Ruegeria gelatinovorans. -

Physiology of Dimethylsulfoniopropionate Metabolism
PHYSIOLOGY OF DIMETHYLSULFONIOPROPIONATE METABOLISM IN A MODEL MARINE ROSEOBACTER, Silicibacter pomeroyi by JAMES R. HENRIKSEN (Under the direction of William B. Whitman) ABSTRACT Dimethylsulfoniopropionate (DMSP) is a ubiquitous marine compound whose degradation is important in carbon and sulfur cycles and influences global climate due to its degradation product dimethyl sulfide (DMS). Silicibacter pomeroyi, a member of the a marine Roseobacter clade, is a model system for the study of DMSP degradation. S. pomeroyi can cleave DMSP to DMS and carry out demethylation to methanethiol (MeSH), as well as degrade both these compounds. Dif- ferential display proteomics was used to find proteins whose abundance increased when chemostat cultures of S. pomeroyi were grown with DMSP as the sole carbon source. Bioinformatic analysis of these genes and their gene clusters suggested roles in DMSP metabolism. A genetic system was developed for S. pomeroyi that enabled gene knockout to confirm the function of these genes.

Author: Brian Shawn Wong Won Advisor: Spencer V. Nyholm Ph.D. University of Connecticut Honors Program Date submitted: 05/11/09 1 Abstract The subject of our study is the Hawaiian bobtail squid, Euprymna scolopes , which is known for its model symbiotic relationship with the bioluminescent bacterium, Vibrio fischeri . The interactions between E. scolopes and V. fischeri provide an exemplary model of the biochemical and molecular dynamics of symbiosis since both members can be cultivated separately and V. fischeri can be genetically modified 1. However, in a laboratory setting, the mortality of embryonic E. scolopes can be a recurrent problem. In many of these fatalities, the egg cases display a pink-hued biofilm, and rosy pigmentation has also been noted in the deaths of several adult squid. To identify the microbial components of this biofilm, we cloned and sequenced the 16s ribosomal DNA gene from pink, culture-grown isolates from infected egg cases and adult tissues. -

AQUATIC MICROBIAL ECOLOGY Vol. 41: 15–23, 2005 Published November 11 Aquat Microb Ecol Marine bacterial microdiversity as revealed by internal transcribed spacer analysis Mark V. Brown1, 2,*, Jed A. Fuhrman1 1Department of Biological Sciences and Wrigley Institute for Environmental Studies, University of Southern California, Los Angeles, California 90089-0371, USA 2Present address: NASA Astrobiology Institute, University of Hawaii, Honolulu, Hawaii 96822, USA ABSTRACT: A growing body of evidence suggests analysis of 16S rRNA gene sequences provides only a conservative estimate of the actual genetic diversity existing within microbial communities. We examined the less conserved internal transcribed spacer (ITS) region of the ribosomal operon to determine the impact microdiversity may have on our view of marine microbial consortia. Analysis of over 500 ITS sequences and 250 associated 16S rRNA gene sequences from an oceanic time series station in the San Pedro Channel, California, USA, revealed that the community in this region is com- posed of large numbers of distinct lineages, with more than 1000 lineages estimated from 3 clusters alone (the SAR11 clade, the Prochlorococcus low-B/A clade 1, and the Roseobacter NAC11-7 clade). Although we found no instances where divergent ITS sequences were associated with identical 16S rRNA gene sequences, the ITS region showed much greater pairwise divergence between clones. By comparison to our 16S rRNA gene–ITS region linked database, we were able to place all ITS sequences into a phylogenetic framework, allowing them to act as an alternative molecular marker with enhanced resolution. Comparison of SAR11 clade ITS sequences with those available in GenBank indicated phylogenetic groupings based not only on depth but also on geography, potentially indicating localized differentiation or adaptation. -

Abstract The extent of genome divergence and the evolutionary events leading to speciation of marine bacteria have mostly been studied for (locally) abundant, free-living groups. The genus Phaeobacter is found on different marine surfaces, seems to occupy geographically disjunct habitats, and is involved in different biotic interactions, and was therefore targeted in the present study. The analysis of the chromosomes of 32 closely related but geographically spread Phaeobacter strains revealed an exceptionally large, highly syntenic core genome. The flexible gene pool is constantly but slightly expanding across all Phaeobacter lineages. The horizontally transferred genes mostly originated from bacteria of the Roseobacter group and horizontal transfer most likely was mediated by gene transfer agents. No evidence for geographic isolation and habitat specificity of the different phylogenomic Phaeobacter clades was detected based on the sources of isolation. In contrast, the functional gene repertoire and physiological traits of different phylogenomic Phaeobacter clades were sufficiently distinct to suggest an adaptation to an associated lifestyle with algae, to additional nutrient sources, or toxic heavy metals.
