摘要

The demographic expansion, urbanization, and economic growth have intensified food demand, leading to an extensive reliance on conventional agrochemical-based approaches that pose significant environmental risks. The rhizosphere microbiome plays a crucial role in enhancing plant productivity and promoting soil health, thereby contributing to long-term, sustainable food production. The mutualistic tripartite association among soil, plants, and microorganisms exhibits multifaceted growth-promoting and stress-tolerant defense mechanisms in response to abiotic and biotic stressors. This review examines plant–microbe interactions in extreme environments, highlighting their role in promoting sustainable agriculture and mitigating stress to enhance crop resilience. It highlights the role of intricate chemical signaling via root exudates in shaping the microbiome and enhancing resilience under adverse conditions. The review suggests that future research should focus on harnessing the rhizosphere microbiota to sustain crop growth under stress. It also discusses the use of technologies such as metagenomics, transcriptomics, and proteomics to understand molecular mechanisms of plant–microbe interactions under stress conditions.
