摘　　要：可变剪接是生物重要的转录后修饰过程,是转录组和蛋白组多样性的重要来源。可变剪接参与了植物众多生理过程,包括植物昼夜节律、生长发育等,在植物响应生物和非生物胁迫过程中尤为普遍。近年来,可变剪接被认为是植物抵御病原菌侵染的重要调控机制。本文综述了可变剪接在植物免疫各个层面的调控作用,包括调节重要免疫受体、R基因、激素信号路径关键基因,此外,一些剪接因子也在植物的免疫过程中起着重要作用。讨论了可变剪接在植物与病原微生物互作过程以及在转录水平参与植物防御基因的动态重编程的重要贡献,并对未来可变剪接在植物免疫中的研究进行了展望,旨在为可变剪接在植物免疫中的研究提供有益的参考。Alternative splicing emerged as an important post-transcriptional process in organisms,and is the main sources of transcriptome and proteome diversity.Alternative splicing functions in a range of physiological processes,including circadian rhythm,growth,development in plant,especially in responding to biotic and abiotic stress.In recent years,alternative splicing has been considered as an important mechanism for plant resisting pathogen infection.This article reviews the regulating role of alternative splicing in different aspects of plant immunity,including the modulation of key immunity receptors,R genes and key genes of hormone signaling pathways.In addition,the role of the modulation of splicing factor in plant immunity is also notable.This article discusses alternative splicing as a key role during plant-pathogen interactions and in dynamic reprogramming of plant resistance genes at transcriptome level,and prospects on the future research of alternative splicing in plant immunity,aiming to provide a beneficial reference for the alternative splicing in plant immunity.
