豌豆种传花叶病毒检测鉴定
摘要
豌豆种传花叶病毒(pea seed-borne mosaic virus,PSbMV)世界广泛分布,在国外已造成豌豆大量减产,国内有仅小范围低密度分布的报道。加拿大豌豆种子中挑拣皱缩、黑斑等症状的豌豆,先采用双抗体夹心酶联免疫吸附(DAS-ELISA)方法检出PSbMV阳性,再利用反转录PCR(RT-PCR)、序列比对分析和构建系统进化树对阳性样本进行验证鉴定,结果显示与PSbMV序列相似度为99.25%,综上确定从进境豌豆种子中检出豌豆种传花叶病毒。
Pea seed-borne mosaic virus is widely distributed in the world causing a large reduction in pea production,and is reported with only small range and low density distribution in China. Samples were seleted from Canada pea seeds with signs of shrinkage and black spots. DAS-ELISA detection revealed that these samples reacted positively with the PSbMV antibody. For further confirmation PSbMV infection,RT-PCR,sequence alignment and phylogenetic analysis were used to verify and identify the ELISA-positive samples. The results showed that the virus from pea seeds shared 99.25% similarity with the PSbMV. It confirmed that imported pea seeds are infected with PSbMV.
