The taxonomy of the large dsDNA viruses has been provided in the VIIIth report of ICTV. The phylogenetic tree of large dsDNA viruses has been constructed using CVTree method (Gao and Qi, BMC Evol. Biol.7(2007)41). In this paper, we use the log-correlation distance method analyze the complete genome of the 124 large dsDNA viruses and construct phylogenetic trees based on compositional vectors of DNA...
The first sequence obtained from a Potyvirus infecting Canna plants (Canna spp.) revealed that it is a new strain of Bean yellow mosaic virus (BYMV), without noticeable recombination with other plant RNA viruses from this region being found. Using a degenerate primer for all Potyvirus, a DNA fragment of about 1.6kb size was amplified from total RNA samples extracted from natural-diseased Canna plants...
The taxonomy of the parvoviruses has been provided in the VIIIth report of ICTV. In this paper, we use two methods (log-correlation distance and mutual information) analyze the complete genome of the 30 parvoviruses and construct phylogenetic trees based on compositional vectors of DNA sequences or protein sequences. The phylogenetic trees show the parvovirus genomes are separated into two major groups...
The analysis on codon usage bias of UL26.5 gene of duck enteritis virus (DEV) may provide a basis for understanding the evolution and pathogenesis of DEV and for selecting appropriate host expression systems to improve the expression of target genes in vivo and in vitro. In this study, the synonymous codon usage in the UL26.5 gene of DEV and 27 reference herpesviruses have been investigated . The...
