| genetic variability and phylogenetic analysis of hosta virus x. | triple gene block 1 (tgb1) and coat protein (cp) sequences of 30 hosta virus x (hvx) isolates from tennessee (tn), usa, were determined and compared with available sequences in genbank. the cps of all known hvx isolates, including those from tn, shared 98.3-100% and 98.2-100% nucleotide and amino acid sequence identity, respectively, whereas tgb1 shared 97.4-100% nucleotide and 97-100% amino acid sequence identity. tgb1 of tn isolates were all longer by one codon from that of a korean isolate, w ... | 2009 | 19838620 |
