香蕉细菌性软腐病菌细胞壁降解酶pelD、pelE基因的克隆表达及活性分析
细胞壁降解酶与植物病害症状有重要的相关性。根据已知软腐病细菌细胞壁降解酶基因序列,设计两对特异性引物,对香蕉细菌性软腐病菌进行PCR克隆,获得具有完整阅读框的基因pelD、pelE序列。通过构建重组表达载体pET28b（＋）-pelD和pET28b（＋）-pelE,重组表达载体转化子在IPTG诱导下,经SDSPAG分析,获得了pelD和pelE的表达蛋白。将两种表达蛋白接种于7～8片叶的粉蕉假茎和离体叶片上,发现接种pelE表达蛋白的粉蕉假茎和叶片出现了腐烂症状,但接种pelD表达蛋白没有引起发病症状。...

Two pairs of specific primers were designed for amplification and cloning gene sequences of Banana soft rot pathogen according to reported cell wall degrading enzyme genes. A complete reading frame sequence of gene pelD and pelE were obtained by cloning technology. The expression vector pET28b （＋） was used to investigate the pelD and pelE gene expression.According to the results of SDS-PAGE,under the inducing of IPTG,transformants of recombinant expression vectors expressed much protein. After the purified protein was inoculated into banana false stem and leaves in vitro,si |
