Increasing evidence indicates that tolerance is a host defense strategy against pathogens as widespread and successful as resistance. Since the concept of tolerance was proposed more than a century ago, it has been in continuous evolution. In parallel, our understanding of its mechanistic bases and its consequences for host and pathogen interactions, ecology, and evolution has grown. This review aims at summarizing the conceptual changes in the meaning of tolerance inside and outside the field of phytopathology, emphasizing difficulties in demonstrating and quantifying this trait. We also discuss evidence of tolerance and current knowledge on its genetic regulation, mechanisms, and role in host–pathogen coevolution, highlighting common patterns across hosts and pathogens. We hope that this comprehensive review attracts more plant pathologists to the study of this key plant defense response.

植物对病原体的耐受性:统一观点。

越来越多的证据表明,耐受性是对抗病原体的宿主防御策略,这些病原体与抗性一样广泛且成功。自从一个多世纪以来提出容忍概念以来,它一直在不断发展。同时,我们对它的机理基础及其对宿主和病原体相互作用,生态学和进化的后果的理解也在增长。这篇综述旨在总结植物病理学领域内外耐受性的概念变化,强调在证明和量化该性状方面的困难。我们还将讨论耐受性的证据以及有关其遗传调控,机制以及在宿主-病原体协同进化中的作用的当前知识,重点介绍宿主和病原体之间的常见模式。
