Complete genome sequence of a tomato spotted wilt virus isolate from China and comparison to other TSWV isolates of different geographic origin.

Tomato spotted wilt virus (TSWV) is well established in most countries worldwide, while it is rarely reported in China. In this report, we have determined the complete nucleotide sequence of a TSWV isolate named TSWV-YN infecting tomato in Yunnan province in southwestern China. The tripartite genome of TSWV-YN was found to consist of L, M and S RNAs of 8910, 4773 and 2970 nt, respectively. The complete genome sequence and the sequence of each genomic region of TSWV-YN from China were compared to those of four other TSWV isolates from Brazil and Korea. The phylogenetic relationship of the Chinese TSWV-YN isolate to other TSWV isolates of different geographic origin, based on the nucleotide sequences of the glycoprotein (GP) and nucleocapsid (N) genes, was also analyzed in this study.
