Abstract The biotic and abiotic stresses are key constraints for food quality, crop yield and global food security. It is necessary to take action to cope with global threats caused by abiotic and biotic stresses such as a reduction in precipitation, increasing drought, salinity, improper temperature, heavy metals, nutrient deficiency and invasion of plants pathogenic microbes, which lead to the reduction of agricultural crops productivity. Plants are severely affected by these stresses and have impaired functioning. One of the strategies to cope with abiotic and biotic stresses is taking advantage of the potential of soil microbes, including plant growth-promoting rhizobacteria (PGPR). The solution is completely environmentally compatible and has no negative effects on the environment. Effective PGPR have a substantial role in biotic and abiotic stresses management, reduce chemical fertilizers and increase the yield of plant cultivars by affecting elemental cycling and nutrient management. These beneficial bacteria can stimulate plant growth under abiotic and biotic stress conditions via mechanisms such as the production of phytohormones, ACC (1-aminocyclopropane-1-carboxylate) deaminase, exopolysaccharides, siderophore, organic acids, nitrogen fixation, phosphate solubilization, various osmolytes, systemic resistance induction, etc. In this review, the role of the PGPR as a new strategy was investigated that may be responsible for the increase in crop productivity and eventually by effectively answering biotic and abiotic stresses leads to food security.

促进植物生长的根际细菌的现状和未来前景：压力条件下农业复兴的经济宝贵资源

摘要 生物和非生物胁迫是食品质量、作物产量和全球粮食安全的关键制约因素。有必要采取行动应对降水减少、干旱、盐碱化、温度不当、重金属、养分缺乏和植物病原微生物入侵等非生物和生物胁迫造成的全球威胁，导致植物病原微生物入侵减少。农作物生产力。植物受到这些压力的严重影响并且功能受损。应对非生物和生物胁迫的策略之一是利用土壤微生物的潜力，包括促进植物生长的根际细菌 (PGPR)。该解决方案完全环保，对环境没有负面影响。有效的 PGPR 在生物和非生物胁迫管理、减少化学肥料和通过影响元素循环和养分管理增加植物品种产量方面具有重要作用。这些有益细菌可以通过产生植物激素、ACC（1-氨基环丙烷-1-羧酸）脱氨酶、胞外多糖、铁载体、有机酸、固氮、磷酸盐增溶、各种渗透剂、系统抗性诱导等。在这篇综述中，研究了 PGPR 作为一种新策略的作用，它可能是提高作物生产力的原因，并最终通过有效应对生物和非生物胁迫导致粮食安全。通过影响元素循环和养分管理减少化学肥料并增加植物品种的产量。这些有益细菌可以通过产生植物激素、ACC（1-氨基环丙烷-1-羧酸）脱氨酶、胞外多糖、铁载体、有机酸、固氮、磷酸盐增溶、各种渗透剂、系统抗性诱导等。在这篇综述中，研究了 PGPR 作为一种新策略的作用，它可能是提高作物生产力的原因，并最终通过有效应对生物和非生物胁迫导致粮食安全。通过影响元素循环和养分管理减少化学肥料并增加植物品种的产量。这些有益细菌可以通过产生植物激素、ACC（1-氨基环丙烷-1-羧酸）脱氨酶、胞外多糖、铁载体、有机酸、固氮、磷酸盐增溶、各种渗透剂、系统抗性诱导等。在这篇综述中，研究了 PGPR 作为一种新策略的作用，它可能是提高作物生产力的原因，并最终通过有效应对生物和非生物胁迫导致粮食安全。
