| 中文摘要: |
| 调查发现北京地区一温室栽培茄子Solanum melongena L.出现严重病毒病。利用基于小RNA的高通量测序技术和RT-PCR方法,明确了引起茄子病害的病毒种类为番茄斑萎病毒,将其命名为TSWV-eggplant分离物。进一步克隆了该病毒的基因组全长(S RNA、M RNA、L RNA),并构建其系统发育树。结果表明,该分离物的S RNA与美国分离物亲缘关系较近,M RNA与中国分离物亲缘关系较近,而L RNA与韩国分离物亲缘关系较近。因此,本研究发现的TSWV分离物与国内已发生报道的分离物不同,该分离物是否存在不同分离物之间基因组的重组需要进一步研究。 |
| 英文摘要: |
| In this study, serious viral disease was found on Solanum melongena L. in a greenhouse in Beijing. With high-throughput sequencing technology based on small RNAs and RT-PCR methods, it was confirmed that the eggplants were infected by tomato spotted wilt virus and named as TSWV-eggplant isolate. Complete genome sequence of the TSWV S RNA, M RNA, L RNA was further cloned and the phylogenetic tree was also constructed. The results showed that the S RNA of TSWV-eggplant was closely related with isolates from America, M RNA was closely related with isolates from China, while L RNA was closely related with isolates from Korea. So the TSWV isolate in this study was different from isolates reported in China and whether the genome of the isolate was recombined from different isolates was needed to be further studied. |
