Abstract excerpt

KEY MESSAGE: The Thr445Met substitution in the novel allele med25-5 uncouples seed dormancy from flowering, and MED25 acts as a negative regulator of seed dormancy via the DOG1 and ABA pathways. MED25, a pivotal subunit of the Mediator complex, regulates diverse biological processes, but its role in seed dormancy remains unclear. Here, we identified a novel MED25 allele, med25-5, harboring a Thr445Met...
