Plant pathogens have evolved numerous strategies to obtain nutritive materials from their host, and plants in turn have evolved the preformed physical and chemical barriers as well as sophisticated two-tiered immune system to combat pathogen attacks. Genetically, plant resistance to pathogens can be divided into qualitative and quantitative disease resistance, conditioned by major gene(s) and multiple genes with minor effects, respectively. Qualitative disease resistance has been mostly detected in plant defense against biotrophic pathogens, whereas quantitative disease resistance is involved in defense response to all plant pathogens, from biotrophs, hemibiotrophs to necrotrophs. Plant resistance is achieved through interception of pathogen-derived effectors and elicitation of defense response. In recent years, great progress has been made related to the molecular basis underlying host-pathogen interactions. In this review, we would like to provide an update on genetic and molecular aspects of plant resistance to pathogens.
植物病原体进化出了许多从宿主获取营养物质的策略，而植物则进化出了预先形成的物理和化学屏障以及复杂的双层免疫系统来抵御病原体的攻击。从遗传学角度来看，植物对病原体的抗性可以分为定性和定量抗性，分别由主基因和多个微效基因控制。定性抗性主要在植物抵御生物病原体的防御中被检测到，而定量抗性则涉及对所有植物病原体的防御反应，包括生物、半生物和坏死病原体。植物抗性是通过拦截病原体衍生的效应子和引发防御反应来实现的。近年来，与宿主-病原体相互作用的分子基础相关的研究取得了重大进展。在这篇综述中，我们将提供植物对病原体抗性的遗传和分子方面的最新进展。
