phylogenetic analysis of members of the phycodnaviridae virus family, using amplified fragments of the major capsid protein gene.algal viruses are considered ecologically important by affecting host population dynamics and nutrient flow in aquatic food webs. members of the family phycodnaviridae are also interesting due to their extraordinary genome size. few algal viruses in the phycodnaviridae family have been sequenced, and those that have been have few genes in common and low gene homology. it has hence been difficult to design general pcr primers that allow further studies of their ecology and diversity. in this stud ...200818359826
two new subfamilies of dna mismatch repair proteins (muts) specifically abundant in the marine environment.muts proteins are ubiquitous in cellular organisms and have important roles in dna mismatch repair or recombination. in the virus world, the amoeba-infecting mimivirus, as well as the recently sequenced cafeteria roenbergensis virus are known to encode a muts related to the homologs found in octocorals and ɛ-proteobacteria. to explore the presence of muts proteins in other viral genomes, we performed a genomic survey of four giant viruses ('giruses') (pyramimonas orientalis virus (pov), phaeocys ...201121248859
