| 英文摘要 | Soil salinization poses a serious threat to global agricultural production. Alfalfa (Medicago sativa L.), as a highquality leguminous forage, shows significant varietal differences in salt tolerance. However, the mechanisms behind these differences, particularly those mediated by rhizosphere microorganisms and root exudates, remain unclear. This study systematically analyzed the phenotypic, physiological, and biochemical responses of three alfalfa varieties (ZT1, ZL1, and ZM1) under salt stress (0, 100, and 200 mM NaCl), ZM1 and ZT1 exhibited enhanced salt tolerance. Combined 16S rRNA sequencing and metabolomic analysis revealed that salt stress reduced alpha diversity and reshaped the structure of the rhizosphere microbial community. Meanwhile, root exudate profiles underwent significant changes, with key metabolites in flavonoid biosynthesis, arginine metabolism, and bacterial chemotaxis pathways being significantly upregulated. Correlation analysis showed close interactions between specific root exudates and rhizosphere bacteria, with the content of important root exudates (flavonoids and saponins) showing positive correlations with the abundance of rhizosphere microorganisms under salt stress. This research elucidates the synergistic role of root exudates and rhizosphere microorganisms in mediating salt tolerance in alfalfa, providing new insights into plant-microbe interactions under abiotic stress and offering potential strategies for improving crop adaptation in saline soils. |
