Pepper veinal mottle virus in Japan is closely related to isolates from other Asian countries, but more distantly to most of those from Africa
Virus Genes 55 (3), 347-355
Abstract: Pepper veinal mottle virus (PVMV) is known to infect chilli pepper and belongs to the Chilli veinal mottle virus phylogroup of potyviruses. PVMV has recently appeared in Japan. In this study, we report six complete genomic sequences of PVMV isolates from chilli pepper (i.e. Capsicum annuum) in Okinawa Islands in Japan, and we determined the evolutionary relationships between Japanese isolates and the isolates reported earlier from African and Asian countries. Complete genomic sequences of the six Japanese PVMV isolates were 9760 nucleotides in length, excluding the nucleotide primer sequences used for amplifying 5' end of the genomes. The major findings of this study are as follows: (1) all the Japanese isolates of PVMV have similar biological and molecular characteristics, indicating the presence of only one population in Japan; (2) there are at least three major phylogenetic groups of PVMV worldwide; (3) PVMV probably originated in East Africa; and (4) all the Asian isolates are closely related to the Ghanaian isolate.
