Volatile organic compounds (VOCs) are chemical compounds whose saturation vapor pressures are greater than 102 kPa at 25 °C. Both plants and microorganisms produce VOCs that allow them to communicate intra- and inter-specifically. By emitting VOCs, plants defend themselves against herbivores and pathogens, warn their neighbors of the attack, compete with other plants, and/or feed microbial populations. Microorganisms emit VOCs to communicate or attack each other. Microbial VOCs (MVOCs) can be of great benefit to plants and their use in agriculture thanks to their ability to inhibit the growth and development of plant pathogens, induce the activation of plant defenses, or promote plant growth and development. In recent years, advances in understanding the importance of microbial volatilome have placed MVOCs as important biotechnological resources in plant production systems.

挥发性有机化合物 (VOC) 是在 25 °C 时饱和蒸气压大于 102 kPa 的化合物。植物和微生物都会产生挥发性有机化合物，使它们能够进行特异性内和特异性间的交流。通过释放 VOC，植物可以抵御食草动物和病原体，警告邻居注意攻击，与其他植物竞争和/或喂养微生物种群。微生物会释放 VOC 来相互交流或攻击。微生物挥发性有机化合物 (MVOC) 能够抑制植物病原体的生长和发育、诱导植物防御功能的激活或促进植物的生长发育，因此对植物及其在农业中的应用非常有益。最近几年，
