植物激素互作是植物防御病原体和昆虫的关键，其中水杨酸（SA）、茉莉酸（JA）和乙烯（ET）起着关键作用。这些低分子量信号通过一个复杂的信号网络，甚至涉及其他激素的参与，关键地触发和调节植物对活体营养型以及坏死营养型病原体的抗性。SA、JA和ET之间的串扰由不同的分子参与者介导，被认为是这些交叉通信信号转导通路的组成部分。最近的进展表明，这些途径之间的积极与消极的相互作用最终使植物能够微调其对特定侵略者的防御。另一方面，病原体已经进化出策略来操纵信号网络，以增强对宿主植物的毒力。本文综述了植物主要防御激素SA、JA和ET在植物病害和免疫反应中的作用及其协同和拮抗作用。与其他激素如脱落酸，生长素，油菜素类固醇，细胞分裂素和褪黑激素的串扰也主要在植物抗病性中讨论。除了我们热衷于激素串扰，这篇评论还强调了潜在的影响，积极和消极的监管相互作用，通过操纵激素信号在植物中开发一个有效的疾病管理策略。
Phytohormone crosstalk is crucial for plant defenses against pathogens and insects in which salicylic acid (SA), jasmonic acid (JA), and ethylene (ET) play key roles. These low molecular mass signals critically trigger and modulate plant resistance against biotrophic as well as necrotrophic pathogens through a complex signaling network that even involves participation of other hormones. Crosstalk among SA, JA and ET is mediated by different molecular players, considered as integral part of these crosscommunicating signal transduction pathways. Recent progress has revealed that the positive versus negative interactions among those pathways ultimately enable a plant to fine-tune its defense against specific aggressors. On the other hand, pathogens have evolved strategies to manipulate the signaling network to their favour in order to intensify virulence on host plant. Here we review recent advances and current knowledge on the role of classical primary defense hormones SA, JA and ET as well as their synergistic and antagonistic interaction in plant disease and immune responses. Crosstalk with other hormones such as abscisic acid, auxin, brassinosteroids, cytokinins and melatonin is also discussed mainly in plant disease resistance. In addition to our keen focus on hormonal crosstalk, this review also highlights potential implication of positive and negative regulatory interactions for developing an efficient disease management strategy through manipulation of hormone signaling in plant.
