Identification of symbiotic nitrogen fixation‐modulating factors in alfalfa and mechanism elucidation of MsHHO3

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Symbiotic nitrogen fixation (SNF), a unique nitrogen acquisition mechanism formed through the interaction between leguminous plants and rhizobia, plays a critical role in reducing dependence on chemical fertilizers. However, in alfalfa (Medicago sativa L.), the mechanisms underlying nitrate‐responsive SNF remain poorly understood. In this study,
