Plant immunity is modulated by several abiotic factors, and microbiome has emerged as a major biotic driver of plant resistance. Recently, a few studies showed that plants also modify resistance to pests and pathogens in their neighborhood. Several types of neighborhood could be identified depending on the biological processes at play: intraspecific and interspecific competition, kin and stranger recognition, plant-soil feedbacks, and danger signaling. This review highlights that molecules exchanged aboveground and belowground between plants can modulate plant immunity, either constitutively or after damage or attack. An intriguing relationship between allelopathy and immunity has been evidenced and should merit further investigation. Interestingly, most reported cases of modulation of immunity by the neighbors are positive, opening new perspectives for the understanding of natural plant communities as well as for the design of more diverse cultivated systems.
植物的免疫受到多种非生物因素的调节，微生物组已成为植物抗性的主要生物驱动因素。最近，有几项研究表明，植物也会改变其对周围害虫和病原体的抗性。根据发挥作用的生物学过程，可以确定几种类型的邻居：种内和种间竞争、亲缘和陌生识别、植物-土壤反馈和危险信号。这篇综述强调了植物之间地上和地下交换的分子可以调节植物的免疫，无论是组成型的还是在损伤或攻击后。已证明化感作用和免疫之间存在着有趣的关系，值得进一步研究。有趣的是，大多数报道的由邻居调节免疫的案例都是积极的，这为理解自然植物群落以及设计更多样化的栽培系统开辟了新的视角。
