近年来，已有１０多个植物抗病基因被克隆并定序。植物抗病基因编码的蛋白，大多含有富氨酸重复单位（ＬＲＲ）和核苷酸结合位点（ＮＢＳ）等结构。在植物与病原物的互作中，这些蛋白可作为受体识别由病原物无毒基因编码的激发子，从而激发一系列防卫反应，使植物表现出抗病性。克隆的植物抗病基因可用于培育基因工程植株而大大加快育种速度。本文对目前植物抗病基因研究中存在的问题及发展前景也进行了探讨。
In recent years, more than 10 plant disease resistance genes have been cloned and sequenced. Plant disease resistance genes encode proteins, most of which contain structures such as the amino acid repeat unit (LRR) and nucleotide binding site (NBS). In plant-pathogen interactions, these proteins act as receptors to recognize excitons encoded by pathogenic non-toxic genes, triggering a series of defensive responses that make plants resistant. Cloned plant disease resistance genes can be used to cultivate genetically engineered plants and greatly accelerate the breeding speed. In this paper, the current problems in plant disease resistance genes and development prospects are also discussed.
