番茄粉虱传双生病毒在中国的传播、分布及分子进化研究进展

The Progress of Sequence Analysis,Spread and Distribution of Whitefly-transmitted Geminivirus in Tomato in China

首先对国内侵染番茄的双生病毒的发生分布进行了综述,发现其病毒症状不完全相同;接着选取了国内外代表性的病毒样品进行了分子系统进化分析,发现国内侵染番茄的双生病毒分别属于3个不同分支,即TYLCV-Isreal、TYLCCNV和ToLCTWV;最后根据国内外病毒的发生及亲缘关系,对中国各地发生的番茄粉虱传双生病毒传播来源进行了推测,以期为今后该病毒的研究及抗病育种提供参考。

A summary of the domestic distribution of the occurance of tomato-infecting geminivirus was concluded,and found that the virus symptoms were not completely same.The typical virus samples from both home and abroad were selected and conducted phylogenetic analysis,and the domestic tomato-infecting geminivirus belonged to three branches：TYLCV-Isreal,TYLCCNV and ToLCTWV.A prediction about the source of whitefly-transmitted geminivirus infecting tomato that occurred in different regions in China was made,according to the occurrence of virus at home and abroad and their genetic relationship.It laid a foundation for future research of this virus and disease resistance breeding.
