1980年,文[14]报导了自上海郊区青菜上分离的长叶车前花叶病毒(RMV);同年,徐来升等从崇明大白菜上分离出芜菁花叶病毒的一个分离株——崇明分离株(T_PMV_(c.m.))(另文讨论);不久,郑礼等又在同种大白菜上分离得芜菁花叶病毒另一分离株——Y_(12)株(T_PMV-Y_(12)).这两个T_PMV分离株虽分离自同一种寄主,但寄主范围和症状却有很大差异,它们代表了T_PMV毒株的两种类型.
In 1980, Wen et al. [14] reported the long-leaved mosaic virus (RMV) isolated from the vegetables in the suburbs of Shanghai. In the same year, Xu Lai-Sheng et al. Isolated an isolate of the turnip mosaic virus from Chongming Chinese cabbage - Chongming (T_PMV_ (cm)) (discussed in other papers). Soon after, Zheng et al. Again isolated another isolate of the Turnip mosaic virus, Y 12 strain (T_PMV-Y 12 ).) Although these two T_PMV isolates are isolated from the same host, the host range and symptoms are quite different and represent both types of T_PMV strain.
