Life-Cycle and Genome of OtV5, a Large DNA Virus of the Pelagic Marine Unicellular Green Alga Ostreococcus tauri

Abstract: Large DNA viruses are ubiquitous, infecting diverse organisms ranging from algae to man, and have probably evolved from an ancient common ancestor. In aquatic environments, such algal viruses control blooms and shape the evolution of biodiversity in phytoplankton, but little is known about their biological functions. We show that Ostreococcus tauri, the smallest known marine photosynthetic eukaryote, whose genome is completely characterized, is a host for large DNA viruses, and present an analysis of the life-… Show more

“…Phycodnaviridae infect a broad range of eukaryotic algae (38). To date, 12 genome sequences of viruses infecting the prasinophyte alga Ostreococcus-a widely distributed marine Mamiellophyceae (39,40) and the smallest known free-living eukaryotic cell-are available (41)(42)(43)(44)(45)(46). These include viruses that infect one of three species: O. tauri, Ostreococcus lucimarinus, and Ostreococcus mediterraneus.…”

“…So far viruses have been reported to infect a wide variety of phytoplankton groups including diatoms (Shirai et al, 2008), dinoflagellates (Yuji et al, 2004), prasinophytes (Derelle et al, 2008), and cyanobacteria (Ortmann et al, 2002), among others.…”

“…Viruses from several other genera in the phycodnavirus family have been sequenced, and members from two of them encode K + channel proteins, including viruses that infect the filamentous brown alga Ectocarpus siliculosus (Delaroque et al, 2001) and viruses that infect some of the smallest known algae (the Prasinophytes), Ostreococcus (Derelle et al, 2008;Weynberg et al, 2009), Micromonas (Moreau et al, 2010), and Bathycoccus spp. (Moreau et al, 2010).…”
