    Complete genome sequence and lytic phase transcription profile of a Coccolithovirus (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-16
    Description: The genus Coccolithovirus is a recently discovered group of viruses that infect the globally important marine calcifying microalga Emiliania huxleyi. Among the 472 predicted genes of the 407,339-base pair genome are a variety of unexpected genes, most notably those involved in biosynthesis of ceramide, a sphingolipid known to induce apoptosis. Uniquely for algal viruses, it also contains six RNA polymerase subunits and a novel promoter, suggesting this virus encodes its own transcription machinery. Microarray transcriptomic analysis reveals that 65% of the predicted virus-encoded genes are expressed during lytic infection of E. huxleyi.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, William H -- Schroeder, Declan C -- Allen, Michael J -- Holden, Matthew T G -- Parkhill, Julian -- Barrell, Bart G -- Churcher, Carol -- Hamlin, Nancy -- Mungall, Karen -- Norbertczak, Halina -- Quail, Michael A -- Price, Claire -- Rabbinowitsch, Ester -- Walker, Danielle -- Craigon, Marie -- Roy, Douglas -- Ghazal, Peter -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1090-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plymouth Marine Laboratory, Prospect Place, The Hoe, Plymouth, PL1 3DH, UK. whw@pml.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16099989" target="_blank"〉PubMed〈/a〉

    A comprehensive survey of the Plasmodium life cycle by genomic, transcriptomic, and proteomic analyses (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-01-08
    Description: Plasmodium berghei and Plasmodium chabaudi are widely used model malaria species. Comparison of their genomes, integrated with proteomic and microarray data, with the genomes of Plasmodium falciparum and Plasmodium yoelii revealed a conserved core of 4500 Plasmodium genes in the central regions of the 14 chromosomes and highlighted genes evolving rapidly because of stage-specific selective pressures. Four strategies for gene expression are apparent during the parasites' life cycle: (i) housekeeping; (ii) host-related; (iii) strategy-specific related to invasion, asexual replication, and sexual development; and (iv) stage-specific. We observed posttranscriptional gene silencing through translational repression of messenger RNA during sexual development, and a 47-base 3' untranslated region motif is implicated in this process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, Neil -- Karras, Marianna -- Raine, J Dale -- Carlton, Jane M -- Kooij, Taco W A -- Berriman, Matthew -- Florens, Laurence -- Janssen, Christoph S -- Pain, Arnab -- Christophides, Georges K -- James, Keith -- Rutherford, Kim -- Harris, Barbara -- Harris, David -- Churcher, Carol -- Quail, Michael A -- Ormond, Doug -- Doggett, Jon -- Trueman, Holly E -- Mendoza, Jacqui -- Bidwell, Shelby L -- Rajandream, Marie-Adele -- Carucci, Daniel J -- Yates, John R 3rd -- Kafatos, Fotis C -- Janse, Chris J -- Barrell, Bart -- Turner, C Michael R -- Waters, Andrew P -- Sinden, Robert E -- New York, N.Y. -- Science. 2005 Jan 7;307(5706):82-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pathogen Sequencing Unit, Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge CB10 1SA, UK. nhall@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15637271" target="_blank"〉PubMed〈/a〉
