Abstract：Endophytic bacteria are a kind of microorganisms that are widely lived in plants,which participate in regulat-ing the growth and development of plants through themselves and their metabolites.This article takes tomato as the object and systematically clarifies the types of endophytic bacteria and the various active metabolites they secrete,including growth regulatory substances IAA,ethylene,phosphorus-solubilizing substances,hydrolases,nitrogen-fixing components and iron carriers.Through precise regulation of nutrient absorption,competitive occupation of dominant ecological sites,and activation of the plant-induced resistance system(ISR)and other pathways,the role in promoting the growth and de-velopment of the host and assisting in resisting pests,diseases and environmental stress.The problems and prospects exist-ing in the research direction of endophytic bacteria in plants are discussed,with the expectation of providing a reference for its application in the high-quality and efficient production of tomato.
