【摘要】 WRKY转录因子在植物应对生物或非生物胁迫的反应及生长和发育中起重要作用,为研究WRKY转录因子在番茄中的功能,本研究根据课题组已经克隆的番茄WRKY转录因子片段设计引物,采用RT-PCR方法,从JA诱导的番茄幼苗中,获得了608bp的cDNA片段。序列分析表明,该序列含有WRKYGQK保守结构域,与Capsicum annuum WRKY-c序列相似性是79%,与Nicotiana tabacum NtWRKY-7序列相似性是74%,表明已经成功克隆了番茄WRKY2基因片段。更多还原

【Abstract】 WRKY protein play an important role both in biotic and abiotic stress,also in growth and development of plant.In order to study the function of WRKY in tomato,the primers were designed according to the cloned WRKY transcription factors.The 608 bp fragment was obtained from tomato with RT-PCR method.Sequential analysis indicated that this sequence contained WRKYGQK conservative domain,and the similarity with Capsicum annuum WRKY-c and Nicotiana tabacum NtWRKY-7 were 79% and 74%,respectively.The results showed that WRKY gene sequence in tomato was cloned successfully.更多还原
