摘要

Abiotic stresses such as drought, salinity, extreme temperatures (cold, hot), heavy metal toxicity, flooding, pollutants, and nutrient imbalances are emerging as major threats to global agri-food and nutritional security, significantly constraining crop productivity and resilience. Nowadays, the situation has deteriorated owing to the accelerated and profound alterations in global climatic patterns. It is utmost need to understand and find out the various adaptive and alleviative practices to reduce the impact, in which plant growth promoting rhizobacteria (PGPR) have the ability to assuage the negative impact of the various stresses and enhanced seed spices productivity and profitability. The interface between PGPR and crops under various stresses are positive worldwide. PGPR play a significant role in enhancing nutrient availability in the soil–plant–microbe system. Additionally, PGPR help lower ethylene levels, increase the concentration of osmolytes, and defend crops from oxidative injure under a diversity of environmental multiple stresses. The application of PGPR to seed spice crops represents a promising strategy to enhance productivity and improve plant resilience under various stress conditions. This review highlights the role of PGPR in mitigating abiotic stresses in seed spice crops and underscores the need for future research to develop effective, long-lasting microbial formulations that support sustainable cultivation under multiple stress conditions.
