摘要

由于土壤盐碱化、气候突变和降雨减少，世界正面临着人口持续增长和可耕地显著减少的问题。这些问题增加了寻找生态上可持续的解决办法以确保全球粮食安全的重要性。促进植物生长的根瘤菌有利于提高植物生产力和抵御环境胁迫。它们可以通过大气固氮、养分循环、磷酸盐增溶、铁载体形成的铁固存以及吲哚-3-乙酸和1-氨基环丙烷-1-羧酸脱氨酶等植物激素的产生来帮助植物。它们还可以用作生物肥料和生物防治剂，因为它们可以产生抗生素、外多糖和水解酶。在这篇综述中，强调了微生物种群（作为微生物接种剂）与植物系统之间的联系，重点是在逆境条件下增强植物发育，农业系统的环境恢复力，生态系统服务和生物挑战。本文还重点介绍了利用先进的分子工具和技术来有效表征土壤微生物群落，它们在胁迫土壤中提高作物产量的重要性，以及未来研究的前景。

A comprehensive evaluation of the potential of plant growth-promoting rhizobacteria for applications in agriculture in stressed environments

The world is facing a consistent increase in human population and a noticeable decrease in cultivable lands due to soil salinization, abrupt climatic changes, and less rainfall. These problems have increased the importance of finding ecologically sustainable solutions to ensure global food security. Plant growth-promoting rhizobacteria can be advantageous to enhancing plant productivity and safeguarding against environmental stresses. They may assist plants by atmospheric nitrogen fixation, nutrient recycling, phosphate solubilization, iron sequestration via siderophore formation, and production of phytohormones like indole-3-acetic acid and 1-aminocyclopropane-1-carboxylate deaminase. They can also be used as biofertilizers and biocontrol agents as they produce antibiotics, exopolysaccharides, and hydrolytic enzymes. In this review, the connections between microbial populations, as microbial inoculants, and plant systems are highlighted, focusing on the enhancement of plant development, environmental resilience of agricultural systems, ecosystem services, and biological challenges under stressed conditions. This review also emphasizes the use of advanced molecular tools and techniques to effectively characterize potent soil microbial communities, their importance in increasing crop yield in stressed soils, and the prospects for future research.
