Abstract:

野生茄托鲁巴姆高抗黄萎病,是研究茄子黄萎病抗性的理想试材。胚胎发育晚期丰富蛋白(LEA蛋白)是植物在逆境条件下生成的一类应激蛋白。研究以1个受黄萎病菌诱导的托鲁巴姆EST为种子序列,结合电子克隆及RT-PCR验证的策略,获得了LEA蛋白基因的全长cDNA序列,命名为StLEA1。该基因的完整开放阅读框为291bp,编码96个氨基酸,编码蛋白的分子量为10.748kDa,等电点为9.913。经序列分析,StLEA1为水溶性蛋白,不存在信号肽,具有LEA5家族的典型结构域和保守序列,预测含有多个磷酸化位点。表达分析表明,托鲁巴姆受黄萎病菌侵染后,StLEA1在根系中上调表达。为探讨野生茄托鲁巴姆抗黄萎病分子机制提供了素材。
