摘　　要：能够促进植物生长的植物根际细菌统称为植物根际促生菌(PGPR)。PGPR的应用可以减少农药化肥的使用,有助于农业可持续性发展。过去二十多年中,围绕PGPR功能与作用机理相关的理论与应用研究取得了显著进展。本文旨在总结PGPR的促生与生防机制,重点探讨PGPR在参与植物营养元素的改善与摄取、产生植物激素、分泌信号小分子、合成挥发性有机化合物促进植物生长以及合成抗生素类物质拮抗植物病原菌五个方面的生物学功能,并探讨了PGPR在基础与应用两方面的后续研究方向,以期为未来PGPR相关研究提供理论参考。The bacteria that live in the rhizosphere and promote the growth of host plants are called plant growth-promoting rhizobacteria(PGPR).PGPR application helps to reduce the use of pesticides and fertilizers and contributes to the sustainable development of agriculture.Over the past 20 years,significant progresses have been made in both theoretical and applied researches of PGPR.This review aims to summarize the mechanisms underlying PGPR growth promotion and disease resistance,including improving nutrient supply and uptake,producing phytohormone and signal molecules,synthesizing volatile organic compounds,and secreting antibiotics.The future research direction of PGPR in both basic and application aspects is also discussed,hoping to provide theoretical reference for future PGPR related research.
