报道了启动子捕获技术在稻瘟病菌遗传转化中的应用。构建了启动子捕获载体pCBGFP和pEGFPHPH,并转化到M.格里西亚产生了1077个潮霉素B抗性转化体的文库。其中448个转化子在不同结构的M.稻瘟病菌在448株转化子中,有3株转化子生长缓慢,5株转化子分生孢子减少,7株转化子致病力明显降低。随机对11个转化子进行基因组Southern杂交检测,其中9个为单拷贝插入。启动子捕获技术已成功应用于M.可作为功能基因组分析的工具。
Application of promoter trapping based on transformation in Magnaporthe grisea is reported in this paper. Two promoter-trapping vectors, designated as pCBGFP and pEGFPHPH, were constructed and transformed into protoplasts of M. Grisea. A library of 1077 transformants resistant to hygromycin B was generated. Of which, 448 transformants were found to express eGFP gene in different structures of M. grisea. Three transformants grew slowly, 5 transformants decreased in conidiation and 7 transformants reduced in pathogenicity greatly among these 448 transformants. Eleven transformants were checked by genomic southern blot randomly, and 9 of which were single-copy insertions. The promoter trapping technique has been applied successfully in M. Grisea and can be used as a tool for functional genomic analysis.
