The plant immune system has evolved to resist attack by pathogens and pests. However, successful phytopathogens deliver effector proteins into plant cells where they hijack the host cellular machinery to suppress the plant immune responses and promote infection. This manipulation of the host cellular pathways is done by the pathogen using various enzymatic activities, protein- DNA or protein- protein interactions. Rice is one the major economically important crops and its yield is affected by several pathogens and pests. In this review, we summarize the various effectors at the plant- pathogen/ pest interface for the major pathogens and pests of rice, specifically, on the mode of action and target genes of the effector proteins. We then compare this across the major rice pathogens and pests in a bid to understand probable conserved pathways which are under attack from pathogens and pests in rice. This analysis highlights conserved patterns of effector action, as well as unique host pathways targeted by the pathogens and pests.
植物免疫系统已经进化到能够抵抗病原体和害虫的攻击。然而，成功的植物病原体将效应蛋白输送到植物细胞中，在那里它们劫持宿主细胞机制以抑制植物免疫反应并促进感染。病原体通过各种酶活性、蛋白质-DNA或蛋白质-蛋白质相互作用来操纵宿主细胞途径。水稻是主要的经济作物之一，其产量受到多种病原体和害虫的影响。在这篇综述中，我们总结了水稻主要病原体和害虫在植物-病原体/害虫界面的各种效应蛋白，具体而言，是效应蛋白的作用模式和靶基因。然后，我们对主要水稻病原体和害虫进行比较，以了解可能受到水稻病原体和害虫攻击的保守途径。该分析突出了效应蛋白作用的保守模式，以及病原体和害虫靶向的独特宿主途径。
