摘要： Background: Pepper veinal mottle virus (PVMV) was well established in Africa, and also reported infecting pepper (Capsicum annuum L) in Taiwan and India. However, there is not available of PVMV in mainland China. Here, the first complete genome sequence of PVMV isolated from pepper in mainland China was reported. Finding: The complete genomic sequence of isolate PVMV-HN isolated from pepper in mainland China is reported in this study. The genome of PVMV-HN is 9793 nucleotides (nt) excluding the poly (A) tail, shares 98-99 % nucleotide sequence identity with those two PVMV isolates from Ghana and Taiwan. Recombinant analysis showed that PVMV-HN probably represents a novel recombinant of PVMV. The phylogenetic relationship of PVMV-HN isolate to other PVMV isolates and other potyviruses based on genome or polyprotein sequence level and CP gene level, was also analyzed in this study. Conclusion: The current study will help to understand phylogenetic relationship of isolate PVMV-HN.
