Many agrochemicals designed to help plants withstand abiotic and biotic stresses can negatively impact the environment. Soil, as an essential natural resource, offers plants organic matter, nutrients, and microbial diversity to thrive in challenging environmental conditions. The soil contains plant growth-promoting bacteria that play an important role in plant/crop productivity, assisting plants through a variety of mechanisms, including nitrogen fixation, phosphate solubilization, phytohormone production, induction of resistance against a wide range of pathogens, and production of microbe-to-plant signals that regulate aspects of plant responses to stress. Plant growth-promoting bacteria such as and can contribute to sustainable agriculture by enhancing nutrient uptake, acting as biocontrol agents, and producing lytic enzymes with the potential to disrupt or destroy pathogenic organisms in important agricultural and medicinal crops including soybean and cannabis. This review explores the mechanisms of action of plant growth-promoting bacteria, focusing on and species, and their potential to enhance, optimize plant growth and promote sustainable agriculture.
许多旨在帮助植物抵御非生物和生物胁迫的农用化学品会对环境产生负面影响。土壤作为一种重要的自然资源，为植物提供有机物质、养分和微生物多样性，使其在具有挑战性的环境条件下茁壮成长。土壤中含有促进植物生长的细菌，这些细菌在植物/作物生产力中发挥着重要作用，通过多种机制协助植物，包括固氮、解磷、产生植物激素、诱导对多种病原体的抗性以及产生调节植物应激反应各方面的微生物到植物的信号。诸如[具体细菌名称1]和[具体细菌名称2]等促进植物生长的细菌可以通过增强养分吸收、充当生物防治剂以及产生具有破坏或摧毁包括大豆和大麻在内的重要农作物和药用作物中致病生物潜力的裂解酶，为可持续农业做出贡献。本综述探讨了促进植物生长的细菌的作用机制，重点关注[具体细菌名称1]和[具体细菌名称2]物种，以及它们增强、优化植物生长和促进可持续农业的潜力。
