Plant-mediated interactions between pathogenic microorganisms and arthropod herbivores occur when arthropod infestation or pathogen infection changes the shared host plant in ways that affect a subsequent attacker of the opposite type. Interest in such "tripartite" interactions has increased as the ecological and plant physiological framework for understanding and contextualizing them has developed. The outcomes of plant-mediated interactions are variable, and only a few provisional patterns can be identified at present. However, these interactions can have important consequences not only for individual pathogens and herbivores, but also for the population dynamics of both types of organisms in managed and natural ecosystems. Research has focused on the role of two plant response pathways in mediating tripartite interactions, one involving jasmonic acid and the other salicylic acid. Further studies of plant-mediated interactions will facilitate an understanding of how plants coordinate and integrate their defenses against multiple biotic threats.

病原微生物与食草节肢动物之间的植物介导的相互作用。

当节肢动物侵染或病原体感染以影响随后的相反类型攻击者的方式改变了共享寄主植物时，就会发生病原微生物与节肢动物食草动物之间的植物介导的相互作用。随着理解和情境化的生态和植物生理学框架的发展，对这种“三方”相互作用的兴趣也增加了。植物介导的相互作用的结果是可变的，目前只能确定几种临时模式。但是，这些相互作用不仅会对单个病原体和草食动物产生重要影响，而且还会对受管理的自然生态系统中两种生物的种群动态产生重要影响。研究集中于两种植物反应途径在介导三方相互作用中的作用，一种涉及茉莉酸，另一种涉及水杨酸。对植物介导的相互作用的进一步研究将促进对植物如何协调和整合其针对多种生物威胁的防御的理解。
