Two specimens from the Philip- pines were resolved as conspecific to the Atlantic A. dendroides in molecular analyses extending its geographic range to the Philippines. In light of new evidence provided by field-collected specimens ofAcanthophora spicifera (M.Vahl) Børgesen (generitype) from Florida and Venezuela, the flattened species A. pacifica(Setchell) Kraft, showed no affin- ity to Acanthophora sensu stricto, suggesting that the genus should be restricted to cylindrical species only.

A combined alignment of nuclear and plastid small subunit rDNA and a data set of Rubisco protein sequences were also studied to complement the understanding of bangiophyte phylogeny and to address red algal secondary symbiosis. Our results are consistent with a monophyletic origin of the Florideophycidae, which form a sister-group to the Bangiales. Bangiales monophyly is strongly supported, although Porphyra is polyphyletic within Bangia. Ban- giophycidae orders such as the Porphyridiales are distributed over three independent red algal lineages. The Compsopogonales sensu stricto, consisting of two freshwater families, Compsopogonaceae and Boldiaceae, forms a well-supported monophyletic grouping. The single taxon within the Rhodochaetales, Rhodochaete parvula, is positioned within a cluster containing members of the Erythropelti- dales. Analyses of Rubisco sequences show that the plastids of the heterokonts are most closely related to members of the Cyanidiales and are not directly related to cryptophyte and haptophyte plastid genomes.

Saunders1,* and Tanya E. Moore1 1Centre for Environmental and Molecular Algal Research, Department of Biology, University of New Brunswick, Frederic- ton, NB E3B 5A3, Canada This review provides a comprehensive summary of the PCR primers and profiles currently in use in our laboratory for red algal DNA barcoding and phylogenetic research. While work focuses on florideophyte taxa, many of the markers have been applied successfully to the Bangiales, as well as other lineages previously assigned to the Bangiophyceae sensu lato. All of the primers currently in use with their respective amplification profiles and strategies are provided, which can include full fragment, overlapping fragments and what might best be called “informed overlapping fragments”, i.e., a fragment for a marker is amplified and sequenced for a taxon and those sequence data are then used to identify the best primers to amplify the remaining fragment(s) for that marker. We extend this strategy for the more variable markers with sequence from the external PCR primers used to “inform” the selection of internal sequencing primers. This summary will hopefully serve as a useful resource to systematists in the red algal community. Key Words: DNA barcode; Florideophyceae; molecular markers; phylogeny; polymerase chain reaction; primers; RedToL INTRODUCTION There can be little question that molecular techniques redtol/) (Vis et al. 2010).

They were additionally subjected to morphological assessment and compared with historical collections from the islands. Six species are presently found in the flora including C. bermudensis comb. nov., based on Halymenia bermudensis, and the following five new species: C. abyssalis, C. antricola, C. atrocostalis, C. lacunicola and C. perparva. Of the eight species known in the western Atlantic flora prior to this study, none is found in Bermuda.

Archaeplastida Genome Studies 75 Acknowledgements 76 References 76 Abstract Oxygenic photosynthesis, the chemical process whereby light energy powers the conversion of carbon dioxide into organic compounds and oxygen is released as a waste product, evolved in the anoxygenic ancestors of Cyanobacteria. Although there is still uncertainty about when precisely and how this came about, the gradual oxygenation of the Proterozoic oceans and atmosphere opened the path for aerobic organisms and ultimately eukaryotic cells to evolve. There is a general consensus that photosynthesis was acquired by eukaryotes through endosymbiosis, resulting in the enslavement of a cyanobacterium to become a plastid. Here, we give an update of the current understanding of the primary endosymbiotic event that gave rise to the Archaeplastida. In addition, we provide an overview of the diversity in the Rhodophyta, Glaucophyta and the Viridiplantae (excluding the Embryophyta) and highlight how genomic data are enabling us to understand the relationships and characteristics of algae emerging from this primary endosymbiotic event.

Lane Jason Kolbe Tatiana Rynearson Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2017 ABSTRACT Parasitism is a common life strategy throughout the eukaryotic tree of life. Many devastating human pathogens, including the causative agents of malaria and toxoplasmosis, have evolved from a photosynthetic ancestor. However, how an organism transitions from a photosynthetic to a parasitic life history strategy remains mostly unknown. Parasites have independently evolved dozens of times throughout the Florideophyceae (Rhodophyta), and often infect close relatives. This framework enables direct comparisons between autotrophs and parasites to investigate the early stages of parasite evolution.

The phylogenetic analyses of 18S rRNA and rbcL genes demonstrate that our specimens are Palmophyllum crassum (Naccari) Rabenhorst, recorded in Japan and clearly distinguished from P. umbracola from New Zealand and California, USA. Palmophyllum crassum grows in the subtidal region, 8-30 m deep, and has a crustose thallus which is closely adherent to substrates such as non-geniculate crustose coralline algae, sponge, shells, or rocks. P. crassum is composed of numerous spherical cells embedded in the gelatinous matrix. The discovery of this ancient green seaweed implies that the Korean coast is one of the hotspots of algal species diversity and has the suitable marine environment for algal speciation. We suggest the grounds to conserve the Korean coast environmentally as the biodiversity center of marine species by studying the phylogeny of seaweeds.

Molecular Barcoding Confirms the Presence of Exotic Asian Seaweeds (Pachymeniopsis Gargiuli and Grateloupia Turuturu) in the Cantabrian Sea, Bay of Biscay
Molecular barcoding confirms the presence of exotic Asian seaweeds (Pachymeniopsis gargiuli and Grateloupia turuturu) in the Cantabrian Sea, Bay of Biscay Marcos Montes1,2, Jose M. Rico2, Eva García-Vazquez1 and Yaisel J. Borrell Pichs1 1 Biología Funcional, University of Oviedo, Oviedo, Asturias, Spain 2 Biología de Organismos y Sistemas (BOS), University of Oviedo, Oviedo, Asturias, Spain ABSTRACT Background. The introduction of exotic species can have serious consequences for marine ecosystems. On the shores of the Cantabrian Sea (North of Spain) there are no routine examinations of seaweeds that combine molecular and morphological methods for early detection of exotic species making it difficult to assess in the early stages their establishment and expansion processes as a result of anthropogenic activities (e.g., shipping and/or aquaculture). Methods. In this work we used both morphological identification and molecular barcoding (COI-5P and rbcL genes) of red algae collected in Asturias, Bay of Biscay (Gijón and Candás harbours) and from the University of Oviedo's herbarium samples. Results. The results confirmed the presence of exotic Asian seaweeds Pachymeniopsis gargiuli and Grateloupia turuturu Yamada on Cantabrian Sea shores. Several individuals of these species were fertile and developing cystocarps when collected, underlining the risk of possible expansion or continued establishment. This study constitutes the first report of the Asian P. gargiuli in this area of the Bay of Biscay. Conclusions.

We made an effort to collect and barcode seaweeds occurring along Southeast coast of India. We barcoded 31 seaweeds species belonging to 21 genera, 14 family, 12 order of 3 phyla (viz., Chlorophyta, Phaeophyta and Rhodophyta). We found 10 species in 3 phyla and 2 genera (Anthophycus and Chnoospora) of Phaeophyta were barcoded for the first time. Uncorrected p-distance calculated using K2P, nucleotide diversity and Tajima’s test statistics reveals highest values among the species of Chlorophyta. Over all K2P distance was 0.36. The present study revealed the potentiality of rbcL gene sequences in identification of all 3 phyla of seaweeds.
