    Single-cell genomics reveals organismal interactions in uncultivated marine protists (2011)
    American Association for the Advancement of Science (AAAS)

    Description: Whole-genome shotgun sequence data from three individual cells isolated from seawater, followed by analysis of ribosomal DNA, indicated that the cells represented three divergent clades of picobiliphytes. In contrast with the recent description of this phylum, we found no evidence of plastid DNA nor of nuclear-encoded plastid-targeted proteins, which suggests that these picobiliphytes are heterotrophs. Genome data from one cell were dominated by sequences from a widespread single-stranded DNA virus. This virus was absent from the other two cells, both of which contained non-eukaryote DNA derived from marine Bacteroidetes and large DNA viruses. By using shotgun sequencing of uncultured marine picobiliphytes, we revealed the distinct interactions of individual cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoon, Hwan Su -- Price, Dana C -- Stepanauskas, Ramunas -- Rajah, Veeran D -- Sieracki, Michael E -- Wilson, William H -- Yang, Eun Chan -- Duffy, Siobain -- Bhattacharya, Debashish -- New York, N.Y. -- Science. 2011 May 6;332(6030):714-7. doi: 10.1126/science.1203163.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bigelow Laboratory for Ocean Sciences, West Boothbay Harbor, ME 04575, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21551060" target="_blank"〉PubMed〈/a〉

    Cyanophora paradoxa genome elucidates origin of photosynthesis in algae and plants (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-22
    Description: The primary endosymbiotic origin of the plastid in eukaryotes more than 1 billion years ago led to the evolution of algae and plants. We analyzed draft genome and transcriptome data from the basally diverging alga Cyanophora paradoxa and provide evidence for a single origin of the primary plastid in the eukaryote supergroup Plantae. C. paradoxa retains ancestral features of starch biosynthesis, fermentation, and plastid protein translocation common to plants and algae but lacks typical eukaryotic light-harvesting complex proteins. Traces of an ancient link to parasites such as Chlamydiae were found in the genomes of C. paradoxa and other Plantae. Apparently, Chlamydia-like bacteria donated genes that allow export of photosynthate from the plastid and its polymerization into storage polysaccharide in the cytosol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Price, Dana C -- Chan, Cheong Xin -- Yoon, Hwan Su -- Yang, Eun Chan -- Qiu, Huan -- Weber, Andreas P M -- Schwacke, Rainer -- Gross, Jeferson -- Blouin, Nicolas A -- Lane, Chris -- Reyes-Prieto, Adrian -- Durnford, Dion G -- Neilson, Jonathan A D -- Lang, B Franz -- Burger, Gertraud -- Steiner, Jurgen M -- Loffelhardt, Wolfgang -- Meuser, Jonathan E -- Posewitz, Matthew C -- Ball, Steven -- Arias, Maria Cecilia -- Henrissat, Bernard -- Coutinho, Pedro M -- Rensing, Stefan A -- Symeonidi, Aikaterini -- Doddapaneni, Harshavardhan -- Green, Beverley R -- Rajah, Veeran D -- Boore, Jeffrey -- Bhattacharya, Debashish -- MSP-14226/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2012 Feb 17;335(6070):843-7. doi: 10.1126/science.1213561.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Evolution, and Natural Resources, Rutgers University, New Brunswick, NJ 08901, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22344442" target="_blank"〉PubMed〈/a〉
