摘要: 在构建TMVcp和CMVcp双价表达载体和建立辣椒高效转化体系的基础上用农杆菌介导法转化辣椒栽培品种农大40和湘研一号。对52个抗卡那霉素再生植株进行点杂交鉴定,结果16株为TMVcp和CMVcp阳性,而PCR检测发现其中有2株为假阳性株。进一步温室攻毒试验表明有7个阳性转基因植株对TMV和CMV同时表现为免疫。

Abstract: A bivalent plant expressing vector carrying TMV cp and CMV cp and CMV cp has been constructed. Transgenic plants resistant to kanamycin have been obtained from to pepper cultivars, Nong da40 and Xiangyan no.1, based on the high efficient pepper gene transformation protocol established previously. The results of molecular assay indicated that sixteen plants presented positive dot blot signals with two of which presented negative PCR signals. The results of leaf surface virus inoculation test indicated that even plants presented immunity to TMV and CMV.

Key words: Double resistance, TMV, CMV, Transgenic pepper plants
