Arbuscular mycorrhizal symbioses have a significant impact on plant interactions with other organisms. Increased resistance to soil-borne pathogens has been widely described in mycorrhizal plants. By contrast, effects on shoot diseases largely rely on the lifestyle and challenge strategy of the attacker. Among the potential mechanisms involved in the resistance of mycorrhizal systems, the induction of plant defenses is the most controversial. During mycorrhiza formation, modulation of plant defense responses occurs, potentially through cross-talk between salicylic acid and jasmonate dependent signaling pathways. This modulation may impact plant responses to potential enemies by priming the tissues for a more efficient activation of defense mechanisms.
丛枝菌根共生对植物与其他生物的相互作用具有重大影响。菌根植物对土传病原体的抗性增强已被广泛报道。相比之下，对地上部病害的影响很大程度上取决于攻击者的生活方式和侵染策略。在菌根系统抗性所涉及的潜在机制中，植物防御的诱导是最具争议的。在菌根形成过程中，植物防御反应会发生调节，这可能是通过水杨酸和茉莉酸依赖的信号通路之间的相互作用实现的。这种调节可能通过使组织对防御机制的更有效激活做好准备，从而影响植物对潜在敌人的反应。
