摘要

Salinity is an important abiotic stress that reduces plant growth and crop yield. Increased salt content led to hyperosmotic stress, oxidative stress and ion imbalance, which frequently resulted in oxidative damage in plants. Natural causes and inadequate irrigation management techniques are the main sources of salinization of the soil. Plants are equipped with numerous strategies such as accumulation of proline, enhanced antioxidant system along with phytohormones synthesis, upregulation of various transporters SOS1, NHX1, HKT1, etc combat salinity stress. Along with plant’s own arsenal nature has provided them a very unique collections of rhizomicrobiome to alleviate various types of stresses such as salinity. This review commences by stressing the importance of rhizomicrobiome-plant interaction in alleviating salinity stress. The review also elucidates the specific mechanisms activated in response to salt stress, revealing their profound effects on dynamic relationship between plants and their rhizomicrobiome. By exploring the genes involved in salt-induced chemo-signal, the review delves into the modulation of gene expression patterns and the broader genetic adaptations that enable plants to thrive in saline environment. The findings contribute to the advancement of knowledge in plant-microbe interactions, with potential applications in developing genetically resilient crops, utilization of plant growth-promoting rhizobacteria (PGPR) and innovative strategies for sustainable agriculture in saline environments.
