Soil is considered as a vital natural resource equivalent to air and water which supports growth of the plants and provides habitats to microorganisms. Changes in soil properties, productivity, and, inevitably contamination/stress are the result of urbanisation, industrialization, and long-term use of synthetic fertiliser. Therefore, in the recent scenario, reclamation of contaminated/stressed soils has become a potential challenge. Several customized, such as, physical, chemical, and biological technologies have been deployed so far to restore contaminated land. Among them, microbial-assisted phytoremediation is considered as an economical and greener approach. In recent decades, soil microbes have successfully been used to improve plants' ability to tolerate biotic and abiotic stress and strengthen their phytoremediation capacity. Therefore, in this context, the current review work critically explored the microbial assisted phytoremediation mechanisms to restore different types of stressed soil. The role of plant growth-promoting rhizobacteria (PGPR) and their potential mechanisms that foster plants' growth and also enhance phytoremediation capacity are focussed. Finally, this review has emphasized on the application of advanced tools and techniques to effectively characterize potent soil microbial communities and their significance in boosting the phytoremediation process of stressed soils along with prospects for future research.
土壤被认为是一种与空气和水同等重要的自然资源，它支持植物的生长，并为微生物提供栖息地。土壤性质、生产力的变化，以及不可避免的污染/胁迫，是城市化、工业化和长期使用合成肥料的结果。因此，在当前的情况下，受污染/胁迫土壤的开垦已成为一个潜在的挑战。迄今为止，已经部署了几种定制的技术，如物理、化学和生物技术，以恢复受污染的土地。其中，微生物辅助植物修复被认为是一种经济且环保的方法。在过去几十年中，土壤微生物已成功用于提高植物耐受生物和非生物胁迫的能力，并增强其植物修复能力。因此，在这种情况下，目前的综述工作批判性地探讨了微生物辅助植物修复机制，以恢复不同类型的胁迫土壤。重点关注了植物促生根际细菌（PGPR）及其促进植物生长和增强植物修复能力的潜在机制。最后，本综述强调了应用先进的工具和技术来有效地描述有潜力的土壤微生物群落及其在促进胁迫土壤植物修复过程中的意义，以及未来研究的前景。
