GbRvd超表达载体的构建及超表达拟南芥的抗病性分析

he Construction of Expression Vector and Verticillium Wilt Resistance Analysis of Cotton GbRvd in Overexpressed Arabidopsis thaliana

中文摘要英文摘要

本研究应用Gateway技术构建了GbRvd的超表达载体,通过PCR检测及测序表明载体构建成功。采用冻融法将超表达载体转入农杆菌菌株中,利用农杆菌介导的方法转化拟南芥,通过卡那霉素筛选和PCR检测获得了转基因阳性植株15棵。利用灌根接菌法对其中3个纯合的T3代转基因株系进行黄萎病抗性鉴定。鉴定结果显示:GbRvd在拟南芥中的超表达显著提高了拟南芥对黄萎病的抗性,进一步证明了GbRvd介导棉花抗黄萎病反应,为一个重要的抗病因子。

In this study, Gateway technology was used to construct the overexpression vector of GbRvd, and the PCR detection and sequencing showed that the vector was constructed successfully. The overexpression vector was transferred into the Agrobacterium tumefaciens by using the method of freezing and thawing, transformation of Arabidopsis thaliana was mediated by Agrobacterium tumefacienand. Fifteen transgenic positive plants were obtained through the screening of the kanamycin and PCR detection. The resistance of Verticillium wilt for three independent T3 transgenic lines was analyzed by soil drenching methods, identification results showed that GbRvd overexpression significantly increased the resistance of Arabidopsis thaliana to Verticillium wilt, which further proved that GbRvd could mediate resistance to the disease as an important factor.
