Abstract excerpt

Nodule senescence in barrel medic (Medicago truncatula) can occur as a natural, developmentally regulated process or be triggered prematurely by environmental stress or ineffective symbiotic interactions. In this study, we examined five M. truncatula Fix⁻ mutants (dnf4, dnf7-2, TR183, TRV36, and TR36) that fail to fix nitrogen to determine whether they share common senescence-related traits. Our findings reveal...
