One of the most important and essential components of sustainable agricultural production is biostimulants, which are emerging as a notable alternative of chemical-based products to mitigate soil contamination and environmental hazards. The most important modes of action of bacterial plant biostimulants on different plants are increasing disease resistance; activation of genes; production of chelating agents and organic acids; boosting quality through metabolome modulation; affecting the biosynthesis of phytochemicals; coordinating the activity of antioxidants and antioxidant enzymes; synthesis and accumulation of anthocyanins, vitamin C, and polyphenols; enhancing abiotic stress through cytokinin and abscisic acid (ABA) production; upregulation of stress-related genes; and the production of exopolysaccharides, secondary metabolites, and ACC deaminase. is a free-living bacterial genus which can promote the yield and growth of many species, with multiple modes of action which can vary on the basis of different climate and soil conditions. Different species of spp. can increase the growth, yield, and biomass of plants by increasing the availability of nutrients; enhancing the solubilization and subsequent uptake of nutrients; synthesizing indole-3-acetic acid; fixing nitrogen; solubilizing phosphorus; promoting the production of phytohormones; enhancing the growth, production, and quality of fruits and crops via enhancing the production of carotenoids, flavonoids, phenols, and antioxidants; and increasing the synthesis of indoleacetic acid (IAA), gibberellins, siderophores, carotenoids, nitric oxide, and different cell surface components. The aim of this manuscript is to survey the effects of spp. and spp. by presenting case studies and successful paradigms in several horticultural and agricultural plants.
生物刺激素是可持续农业生产中最重要且必不可少的组成部分之一，它正作为基于化学产品的显著替代品崭露头角，以减轻土壤污染和环境危害。细菌植物生物刺激素对不同植物最重要的作用方式包括增强抗病性；激活基因；产生螯合剂和有机酸；通过代谢组调节提高品质；影响植物化学物质的生物合成；协调抗氧化剂和抗氧化酶的活性；花青素、维生素C和多酚的合成与积累；通过细胞分裂素和脱落酸（ABA）的产生增强非生物胁迫；上调与胁迫相关的基因；以及产生胞外多糖、次生代谢产物和ACC脱氨酶。[具体细菌属名]是一种自由生活的细菌属，可促进多种植物的产量和生长，其多种作用方式会因不同的气候和土壤条件而有所不同。[具体细菌属名]的不同物种可通过提高养分有效性；增强养分的溶解及随后的吸收；合成吲哚 - 3 - 乙酸；固氮；溶解磷；促进植物激素的产生；通过增加类胡萝卜素、黄酮类化合物、酚类和抗氧化剂的产生来提高水果和作物的生长、产量和品质；以及增加吲哚乙酸（IAA）、赤霉素、铁载体、类胡萝卜素、一氧化氮和不同细胞表面成分的合成，来提高植物的生长、产量和生物量。本手稿的目的是通过介绍几种园艺和农业植物中的案例研究和成功范例，来综述[具体细菌属名]和[具体细菌属名]的作用效果。
