Advances on the Executor Resistance Genes in Plants
The survive of plants is mainly attributed to their complex and sophisticated immune defense system that has evolved through the process of battles against pathogens.The cloning and functional research of disease resistance(R)genes have greatly facilitated people's understanding of plant immune defense systems.Executor(E)genes,as a new type of plant disease resistance genes,has unique disease resistance characteristics and is also an important resource for disease resistance genes,making it a research hotspot in the field of plant immunity.In recent years,significant pro-gress has been made in the cloning and functional mechanism research of E genes,however,there is no Chinese review about them.This article comprehensively summarizes the protein sequence characteristics,interaction mechanisms with pathogens,biological functions and breeding applications of the E genes,aiming to provide important references for un-derstanding the molecular mechanisms of plant-pathogen interactions and disease-resistant breeding of crops.
