摘要
从贵州威宁等地采集马铃薯病叶样本,采用试管捕捉反转录PCR(tube-capture-RT-PCR,TC-RT-PCR)的方法克隆出714 bp的PVX CP基因,编码237个氨基酸残基。系统进化分析表明,PVX CP基因可分为两大类群,推测分离物属于X3株系,并建议重型花叶也可作为PVX病叶样本。
Potato leaves with PVX infection symptoms were collected from Guizhou Province including Weining County.A PVX CP gene of 714bp encoding 237 amino acid residues was cloned with the tube capture RT-PCR (TC-RT-PCR) method.Phylogenic analysis revealed that PVX CP genes can be divided into two groups,and the isolate was estimated to be X3 strain.Furthermore,We suggested that severe mosaic leaves could also be samples for PVX gene cloning.
