Abstract

Soil salinization threatens worldwide wheat production by inhibiting plant growth and changing rhizosphere microbial populations. Yet global food demand is increasing and improving wheat tolerance to salinity stress is critical for agricultural sustainability. This paper explores the adaptive evolution and symbiotic mechanisms of these microorganisms in saline-alkali environments. The results suggest that the dynamic and adaptive characterization of wheat inter-root microbial communities provides interesting avenues for improving salt tolerance. Salinity stress affects microbial composition, promoting salt-tolerant taxa such as Bacillus and Pseudomonas. These microorganisms increase wheat resistance via biofilm formation, osmoprotection, and enhanced ion homeostasis. Furthermore, beneficial bacteria including Ascomycetes, Actinobacteria, Thick-walled Bacteria, and Mycobacteria also promote food cycling, enhance antioxidant defenses, and reduce salt-induced stress. New advances in high-throughput sequencing, transcriptomics and metabolomics have revealed the molecular processes that make these relationships possible. The paper demonstrates the efficacy of microbial inoculants in promoting wheat development in saline soils. Incorporating these insights into agricultural methods may enhance crop sustainability and food security.
