恶苗病是一种由藤仓镰刀菌(Fusarium fujikuroi)引起的全球性水稻病害,病原菌通过分泌赤霉素(GA, gibberellin)、细胞壁降解酶及效应蛋白,破坏宿主生理代谢过程,并抑制其免疫反应,最终导致植株徒长、产量下降。本文系统总结了人工接种法和分子标记基因型鉴定技术在水稻恶苗病抗性鉴定评价中的应用,比较了已有抗性种质资源的筛选结果和评价指标,为深入挖掘关键抗病基因、培育抗病品种奠定了重要基础。同时,针对抗性种质资源匮乏等问题,本文提出未来应结合高通量筛选与多环境田间验证,建立标准化、可重复且适用不同种质背景的水稻恶苗病抗性鉴定平台,为关键抗病基因深入挖掘和抗病资源评价打下坚实基础。
Bakanae disease, caused by Fusarium fujikuroi, is a globally important fungal disease of rice. The pathogen produces gibberellins, cell wall-degrading enzymes, and effector proteins that interfere with host metabolic processes and suppress immune responses, ultimately leading to elongate seedling growth and reduce yield. This article systematically reviews the application of artificial inoculation methods and molecular marker-assisted genotyping techniques in the evaluation of rice resistance to bakanae disease. It compares existing screening results and evaluation criteria for resistant germplasm resources, laying an important foundation for in-depth exploration of key disease-resistant genes and the development of resistant rice varieties. Furthermore, in response to challenges such as the scarcity of resistant germplasm, this paper proposes that future efforts should integrate high-throughput screening with multi-environment field validation to establish a standardized, reproducible, and widely applicable resistance evaluation platform for bakanae disease across diverse genetic backgrounds. This will provide a solid basis for further mining of critical resistance genes and the assessment of resistant resources.
