Rice black-streaked dwarf virus (RBSDV) is an economically important virus that causes maize rough dwarf disease and rice black-streaked dwarf disease in East Asia. To study RBSDV variation and recombination, we examined the segment 9 (S9) sequences of 49 RBSDV isolates from maize and rice in China. Three S9 recombinants were detected in Baoding, Jinan, and Jining, China. Phylogenetic analysis showed that Chinese RBSDV isolates could be classified into two groups based on their S9 sequences, regardless of host or geographical origin. Further analysis suggested that S9 has undergone negative and purifying selection.
水稻黑条矮缩病毒（RBSDV）是一种具有重要经济影响的病毒，在东亚地区可导致玉米粗缩病和水稻黑条矮缩病。为研究RBSDV的变异和重组情况，我们检测了来自中国玉米和水稻的49个RBSDV分离株的第9节段（S9）序列。在中国保定、济南和济宁检测到3个S9重组体。系统发育分析表明，中国的RBSDV分离株根据其S9序列可分为两组，与宿主或地理来源无关。进一步分析表明，S9经历了负向和纯化选择。
