摘　　要：水稻是重要的粮食作物,在自然生长状态下会面临各种病原体、昆虫的侵害。稻瘟病、白叶枯病和褐飞虱虫害是对水稻产量和品质影响最严重的三种水稻病害,每年因各种水稻病害造成大量的粮食损失。植物与病原体长期斗争的过程进化出了植物免疫系统。植物免疫系统由两道免疫防线守护植物抵御病原体的入侵。第一层免疫防线由植物细胞表面的免疫受体组成,也是植物的基础免疫防线;第二层免疫防线主要以细胞内的免疫受体NLRs (Intracellular Nucleotide-Binding Site and Leucine-Rich Repeat Receptors)介导的免疫反应。NLRs介导的免疫防御反应是水稻免疫重要组成部分,参与了水稻抵抗稻瘟病菌、白叶枯病菌和褐飞虱的免疫应答过程。Rice is an important food crop, which will face the invasion of various pathogens and insects in the natural growth state. Rice blast, bacterial blight and brown plant hopper are the three most serious rice diseases affecting rice yield and quality, which cause a large amount of grain loss every year. The process of long-term struggle between plants and pathogens has evolved a plant immune system. The plant immune system guards plants against the invasion of pathogens by two immune defense lines. The first layer of immune defense line is composed of immune receptors on the surface of plant cells, which is also the basic immune defense line of plants. The second layer of immune defense is mainly mediated by intracellular immune receptors NLRs. The immune defense response mediated by NLRs is an important part of rice immunity, which is involved in the immune response process of rice against Magnaporthe Oryzae, Xanthomonas oryzae Pv. Oryzae and Nilaparvata lugens.
