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.

植物易感反应：植物与病原体相互作用被低估的一面

植物对病原菌的易感性通常是从抗性丧失的角度来考虑的。然而，易感性不能等同于植物的被动性，因为病原体可能需要主动的宿主合作才能繁殖并引起疾病。这种合作包括诱导称为易感反应的反应，这些反应将植物从自主的生物单位转变为病理系统的组成部分。文献中很少讨论诱导易感性（至少与诱导抗性相比），尽管这种现象对植物 - 病原体相互作用和疾病进展具有根本影响。本综述旨在总结目前关于植物易感反应及其调控的知识。我们根据其后果突出了两类主要的易感反应，并指出了易感反应相关研究与农业实践的相关性。我们希望这篇综述能引起人们对植物-病原体相互作用这一被低估的方面的兴趣。
