| 英文摘要 | Alfalfa, the king of forage, offers high-quality feed and ecological benefits, but salt stress limits its growth and yield. Salt-tolerant alfalfa varieties were selected using ZT1, developed via space-induced mutation breeding, and ZL2, bred through conventional hybridization. By combining metabolomic and 16S rRNA sequencing data from two varieties (ZT1 and ZL2) under gradient NaCl treatments, we uncovered divergent adaptation mechanisms. ZT1 sustained higher photosynthetic performance, achieved better ion balance, and accumulated more flavonoids and terpenoids. It engaged in quorum sensing and beneficial microbial cooperation, adopting an energy-efficient, microbe-assisted strategy to mitigate stress. In contrast, ZL2 relied on broad metabolic reprogramming and enriched microbes linked to defense, demonstrating a more autonomous, energetically costly survival response under high salinity. Microbial diversity decreased with increasing salt stress, but ZT1 maintained a more stable community structure. These findings advance our understanding of plant-microbe-metabolite crosstalk under stress and support the development of breeding or microbiome-based strategies to enhance salt tolerance in Medicago sativa L. |
