Rice sheath blight disease, caused by the basidiomycetous necrotroph Rhizoctonia solani, became one of the major threats to the rice cultivation worldwide, especially after the adoption of high-yielding varieties. The pathogen is challenging to manage because of its extensively broad host range and high genetic variability and also due to the inability to find any satisfactory level of natural resistance from the available rice germplasm. It is high time to find remedies to combat the pathogen for reducing rice yield losses and subsequently to minimize the threat to global food security. The development of genetic resistance is one of the alternative means to avoid the use of hazardous chemical fungicides. This review mainly focuses on the effort of better understanding the host-pathogen relationship, finding the gene loci/markers imparting resistance response and modifying the host genome through transgenic development. The latest development and trend in the R. solani-rice pathosystem research with gap analysis are provided.

了解水稻纹枯病抗性：后面的路和前面的路。


水稻纹枯病由担子菌类坏死微生物立枯丝核菌引起，已成为全球水稻种植的主要威胁之一，特别是在采用高产品种之后。该病原体的管理具有挑战性，因为其宿主范围广泛，遗传变异性高，而且无法从现有的水稻种质中找到任何令人满意的自然抗性水平。现在正是寻找对抗病原体的补救措施，以减少水稻产量损失，从而最大限度地减少对全球粮食安全的威胁的时候了。发展遗传抗性是避免使用危险化学杀菌剂的替代手段之一。本综述主要集中于更好地理解宿主与病原体的关系、寻找赋予抗性反应的基因位点/标记以及通过转基因开发修改宿主基因组的努力。通过差距分析，提供了水稻病原菌病理系统研究的最新进展和趋势。
