RNAi介导的转基因番茄抗TYLCV研究
本研究将TYLCV的AC1和AC2基因中的保守序列嵌合并构建反向重复序列的RNAi载体pBI121-AC1-AC2,通过农杆菌介导法转化番茄获得13株再生植株。结果表明,PCR及RT-PCR检测发现有3株转基因番茄成功表达T-DNA插入的外源基因片段。利用侵染性克隆农杆菌注射及烟粉虱传毒两种接种方法对其进行了抗性鉴定,表明2株转基因番茄植株对TYLCV表现抗性,为抗TYLCV育种提供了新的种质资源。...

| Notes | 51-1213/S In order to generate engineered resistance to TYLCV,the pBI121-AC1-AC2 RNAi expression vector by using AC1 and AC2 gene of TYLCV was constructed,and thirteen regenerated tomato plants were obtained by agrobacterium-mediated transformation. The results showed that RNA interference sequence of the TYLCV by PCR and RT-PCR identification was introduced into the genome successfully,and three transgenic tomato plants were obtained. Of which,two transgenic plants were confirmed to be resistant to TYLCV significantly,which would provide new germplasm resources for breeding of resistance to TYLCV.
