摘要
水稻(Oryza sativa)是世界上最重要的粮食作物之一,其产量影响全球粮食安全。然而,水稻的各种病害对粮食安全构成极大威胁。其中,稻瘟病、白叶枯病和纹枯病是影响全球水稻生产的3种主要病害,培育具有广谱抗病性的水稻品种迫在眉睫。近年来,水稻抗病调控机制研究取得了突破性进展。该文从水稻自身免疫反应以及抗病相关基因功能等方面综述了水稻抗病调控机制,提出今后需解决的问题,以期为水稻广谱抗病育种提供参考。
Rice(Oryza sativa)is one of the most vital food crops globally,and its yield plays a crucial role in ensuring food security.However,various diseases affecting rice pose significant threats to this security.Among these,rice blast,bacterial blight,and sheath blight are the three predominant diseases impacting global rice production.Consequently,there is an urgent need to breed and cultivate rice varieties with broad-spectrum disease resistance.In recent years,substantial advancements have been made in understanding the regulatory mechanisms underlying disease resistance in rice.This paper reviews these mechanisms from multiple perspectives,including the plant’s intrinsic immune responses and the functional dynamics of resistance genes.Furthermore,it highlights pressing issues that require immediate attention to facilitate broad-spectrum disease-resistant breeding efforts for rice.
