Plant growth-promoting rhizobacteria (PGPR) are beneficial plant symbionts that have been successfully used in agriculture to increase seedling emergence, plant weight, crop yield, and disease resistance. Some PGPR strains release volatile organic compounds (VOCs) that can directly and/or indirectly mediate increases in plant biomass, disease resistance, and abiotic stress tolerance. This mini-review focuses on the enhancement of plant abiotic stress tolerance by bacterial VOCs. The review considers how PGPR VOCs induce tolerance to salinity and drought stress and also how they improve sulfur and iron nutrition in plants. The potential complexities in evaluating the effects of PGPR VOCs are also discussed.
植物促生根际细菌（PGPR）是有益的植物共生体，已成功应用于农业领域，以提高种子出苗率、植株重量、作物产量和抗病性。一些PGPR菌株会释放挥发性有机化合物（VOCs），这些化合物可直接和/或间接介导植物生物量增加、抗病性增强以及非生物胁迫耐受性提高。本综述聚焦于细菌挥发性有机化合物对植物非生物胁迫耐受性的增强作用。该综述探讨了PGPR挥发性有机化合物如何诱导植物对盐胁迫和干旱胁迫的耐受性，以及它们如何改善植物的硫和铁营养状况。文中还讨论了评估PGPR挥发性有机化合物作用效果时可能存在的复杂性。
