| 摘 要： | 通过表型鉴定、反转录PCR和实时定量PCR方法,利用转基因和非转基因水稻植株,研究由Rxol基因介导的,水稻对细菌性条斑病菌的抗性反应。结果观察到3个涉及过敏性反应的基因由Rxol基因诱导表达,并对其进行了分析。这3个基因参与编码病程相关蛋白,在转基因水稻植株中呈上调表达,表明水杨酸信号转导途径在抗性反应中发挥重要的作用。

| Abstract: | Phenotype,RT-PCR and real time PCR experiments were performed to reveal the resistance reaction of rice to Xanthomonas oryzae pv.oryzicola mediated by Rxo1 using a pair of transgenic and non-transgenic rice lines.Our results indicated that Rxo1 trigged a typical hypersensitive reaction(HR)based on the observation and expression analysis of 3 gene involved in HR.3 genes involved in coding pathogenesis-related proteins also specifically up-regulated in transgenic rice plants,suggesting that salicylic acid(SA)... |
