背景：芜菁花叶病毒是侵染十字花科作物和观赏植物的一种最广泛、最重要的经济病毒。结果：测定了90个分离物的3‘端基因组序列，并与国内现有分离物进行了比较分析，以了解中国萝卜分离株系的遗传结构。结果表明，中国萝卜上的TuMV分离物形成了亚洲BR、基本BR和世界B三个类群。其中一半以上的菌株(52.54%)聚为BR基群，并可进一步分为3个亚群。亚组I和亚组II的TuMV Basis-BR分离物与日本株在遗传上是同源的，而亚组III的分离物则形成了不同的谱系。TuMV BASIC-BRⅡ和BRⅢ亚群是新出现的，处于扩张状态。中国萝卜TuMV群体处于负选择状态。来自泰安、潍坊和长春的TuMV种群间的基因流动频繁。结论：芜菁花叶病毒种群的遗传结构揭示了一个新的新兴谱系在中国中的迅速扩张。
Background:Turnip mosaic virus (TuMV) is one of the most widespread and economically important virus infecting both crop and ornamental species of the family Brassicaceae. TuMV isolates can be classified to five phylogenetic lineages, basal-B, basal-BR, Asian-BR, world-B and Orchis.Results:To understand the genetic structure of TuMV from radish in China, the 3'-terminal genome of 90 TuMV isolates were determined and analyzed with other available Chinese isolates. The results showed that the Chinese TuMV isolates from radish formed three groups: Asian-BR, basal-BR and world-B. More than half of these isolates (52.54%) were clustered to basal-BR group, and could be further divided into three sub-groups. The TuMV basal-BR isolates in the sub-groups I and II were genetically homologous with Japanese ones, while those in sub-group III formed a distinct lineage. Sub-populations of TuMV basal-BR II and III were new emergent and in a state of expansion. The Chinese TuMV radish populations were under negative selection. Gene flow between TuMV populations from Tai'an, Weifang and Changchun was frequent.Conclusions:The genetic structure of Turnip mosaic virus population reveals the rapid expansion of a new emergent lineage in China.
