| 摘 要： | 番茄黄化曲叶病毒(tomato yellow leaf curl virus, TYLCV)是一种由烟粉虱传播的单链环状DNA病毒, 在田间可与多种病毒发生复合侵染, 如番茄褪绿病毒(tomato chlorosis virus, ToCV)等?本文对比了TYLCV单独侵染和TYLCV与ToCV复合侵染对烟粉虱获取和传播TYLCV的影响?结果表明, 与取食TYLCV单独侵染的番茄相比, 取食复合侵染番茄的烟粉虱对TYLCV的传毒率显著提高, 且番茄植株和烟粉虱体内TYLCV的病毒积累量也显著提高?试验结果说明复合侵染会提高烟粉虱的传毒率, 促进TYLCV的发生与流行?

| Abstract: | Tomato yellow leaf curl virus (TYLCV) is a single-strand circular DNA virus transmitted by Bemisia tabaci, which can co-infect plants with multiple plant viruses in the field, such as tomato chlorosis virus (ToCV) and so on. RT-PCR and real-time quantitative PCR were used to clarify the influence of co-infection of TYLCV and ToCV on the acquisition and transmission of TYLCV by B. tabaci in this study. The results showed that, the rate of TYLCV transmited by B. tabaci feeding on the co-infected tomato plants was significantly increased, compared with those B. tabaci feeding on the tomato infected by TYLCV alone, and the virus accumulation of TYLCV in tomato plants and B. tabaci was also significantly improved compared with the tomato plants infected with TYLCV alone. Our results revealed that co-infection of TYLCV and ToCV in the field increased the transmission rate by B. tabaci, and promoted the spread and epidemic of TYLCV. |
