[Computational genome analysis of three marine algoviruses]
Abstract:
Computational analysis of genomic sequences of three new marine algoviruses: Tetraselmis viridis virus (TvV-S20 and TvV-SI1 strains) and Dunaliella viridis virus (DvV-SI2 strain) was conducted. Both considerable similarity and essential distinctions between studied strains and the most studied marine algoviruses of Phycodnaviridae family were revealed. Our data show that the tested strains are new viruses with the following features: only they were isolated from marine eukaryotic microalgae T. viridis and D. viridis, coding sequences (CDSs) of their genomes are localized mainly on one of the DNA strands and form several clusters with short intergenic spaces; there are considerable variations in genome structure within viruses and their strains; viral genomic DNA has a high GC-content (55.5 - 67.4%); their genes contain no well-known optimal contexts of translation start codones, and the contexts of terminal codons read-through; the vast majority of viral genes and proteins do not have any matches in gene banks.
