Plant susceptibility to pathogens is usually considered from the perspective of the loss of resistance. However, susceptibility cannot be equated with plant passivity since active host cooperation may be required for the pathogen to propagate and cause disease. This cooperation consists of the induction of reactions called susceptible responses that transform a plant from an autonomous biological unit into a component of a pathosystem. Induced susceptibility is scarcely discussed in the literature (at least compared to induced resistance) although this phenomenon has a fundamental impact on plant-pathogen interactions and disease progression. This review aims to summarize current knowledge on plant susceptible responses and their regulation. We highlight two main categories of susceptible responses according to their consequences and indicate the relevance of susceptible response-related studies to agricultural practice. We hope that this review will generate interest in this underestimated aspect of plant-pathogen interactions.
植物对病原体的易感性通常从抗性丧失的角度来考虑。然而,易感性不能等同于植物的被动性,因为病原体的繁殖和致病可能需要宿主的主动配合。这种配合包括诱导反应,称为感病反应,使植物从自主的生物单位转变为病理系统的一个组成部分。尽管这种现象对植物-病原体相互作用和疾病进展有根本性的影响,但在文献中很少讨论诱导易感性(至少与诱导抗性相比)。本综述旨在总结植物感病反应及其调控的最新知识。我们根据感病反应的后果将其分为两大类,并指出与感病反应相关的研究与农业实践的相关性。我们希望本综述能引起人们对植物-病原体相互作用这一被低估方面的兴趣。
