The plant-associated microbial community (microbiome) has an important role in plant-plant communications. Plants decipher their complex habitat situations by sensing the environmental stimuli and molecular patterns and associated with microbes, herbivores and dangers. Perception of these cues generates inter/intracellular signals that induce modifications of plant metabolism and physiology. Signals can also be transferred between plants via different mechanisms, which we classify as wired- and wireless communications. Wired communications involve direct signal transfers between plants mediated by mycorrhizal hyphae and parasitic plant stems. Wireless communications involve plant volatile emissions and root exudates elicited by microbes/insects, which enable inter-plant signalling without physical contact. These producer-plant signals induce microbiome adaptation in receiver plants via facilitative or competitive mechanisms. Receiver plants eavesdrop to anticipate responses to improve fitness against stresses. An emerging body of information in plant-plant communication can be leveraged to improve integrated crop management under field conditions.
植物相关的微生物群落（微生物组）在植物间的交流中起着重要作用。植物通过感知环境刺激和分子模式，并与微生物、草食动物和危险相关联，来破译其复杂的栖息地情况。对这些线索的感知会产生细胞内/间信号，从而诱导植物代谢和生理的改变。信号也可以通过不同的机制在植物间传递，我们将其分为有线和无线通信。有线通信涉及通过菌根菌丝和寄生植物茎直接在植物间传递信号。无线通信涉及微生物/昆虫诱导的植物挥发物排放和根系分泌物，它们能够在没有物理接触的情况下进行植物间信号传递。这些生产者植物信号通过促进或竞争机制诱导接收植物的微生物组适应。接收植物偷听以预测反应，以提高对压力的适应能力。在植物间交流方面，越来越多的信息可以被利用来改善田间条件下的综合作物管理。
