摘要
稻瘟病分子生物学发展迅速 ,已分子标记定位的稻瘟病主效抗性基因 15个 ,微效抗性基因 3个 ;水稻抗稻瘟病基因Pi-ta和Pi-b已成功克隆。稻瘟病菌系谱与致病型关系可分为简单与复杂两种类型。本文对水稻抗稻瘟病基因的定位和克隆 ,稻瘟病菌群体遗传结构、致病性遗传、基因组分析、无毒基因克隆、准性生殖等研究进展进行了评述。
Great achievements have been made in the study of rice blast at molecular levels in recent years. 15 major and 3 minor blast-resistance genes have been mapped by RFLP; So far, two blast-resistance genes have been cloned from rice. The relationships between lineage and pathotype of Magnaporthe grisea were simple or complex. Paper here reviews on the researching progresses in tagging and cloning the blast-resistance genes of rice Oryza sativa, in the population genetic structure, pathogenicity genetics, genome analyses, cloning avirulence genes and parasexuality of Magnaporthe grisea.
