Beschreibung:
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〉
