Rice crops are severely damaged by diseases caused by bacterial, fungal, and viral pathogens. Application of host resistance to these pathogens is the most economical and environmentally friendly approach to solve this problem. Quantitative resistance conferred by quantitative trait loci (QTL) is a valuable resource for the improvement of rice disease resistance. Although numerous resistance QTL against rice diseases have been identified, these resources have not been used effectively in rice improvement because the genetic control of quantitative resistance is complex and the genes underlying most of the resistance QTL remain unknown. This review focuses on the latest molecular progress in quantitative disease resistance in rice. This knowledge will be helpful for characterizing more resistance QTL and turning the quantitative resistance into actual resources for rice protection.
水稻作物受到细菌、真菌和病毒病原体引起的疾病的严重影响。应用宿主抗性来对抗这些病原体是解决这个问题的最经济和环保的方法。由数量性状位点 (QTL) 赋予的数量抗性是改善水稻抗病性的宝贵资源。尽管已经鉴定出许多针对水稻病害的抗性 QTL，但由于数量抗性的遗传控制较为复杂，并且大多数抗性 QTL 背后的基因仍然未知，因此这些资源尚未在水稻改良中得到有效利用。本文综述了水稻数量抗性的最新分子进展。这些知识将有助于鉴定更多的抗性 QTL，并将数量抗性转化为水稻保护的实际资源。
