The rhizosphere, an intricate zone surrounding plant roots, serves as a crucial interface where dynamic interactions between plants and microorganisms occur. This symbiotic relationship plays a pivotal role in nutrient cycling, plant growth, and environmental processes. In the context of environmental contamination, phytoremediation emerges as a promising approach for mitigating pollutants. By harnessing the natural abilities of plants and associated microorganisms, phytoremediation offers a sustainable and cost-effective solution for remediating contaminated sites. Plant growth-promoting rhizobacteria (PGPR) play a key role in enhancing phytoremediation efficiency through various mechanisms, including nutrient solubilization, phytohormone production, and stress tolerance induction. Recent research focuses on optimizing PGPR capabilities to improve their effectiveness in remediation processes. Strategies such as genetic engineering and biotechnological interventions aim to enhance PGPR-mediated phytoremediation by tailoring microbial-plant interactions and increasing pollutant uptake and degradation. Overall, the integration of PGPR into phytoremediation strategies presents promising prospects for addressing environmental contamination challenges and advancing sustainable remediation technologies.
