The DOF Protein DAG1 and the DELLA Protein GAI Cooperate in Negatively Regulating the AtGA3ox1 Gene

Dear Editor, Seed germination is controlled by multiple endogenous and environmental factors, which are integrated to trigger this developmental process at the right time. Gibberellins (GAs) are known to induce this process, and the levels of GAs are modulated by light—one of the most important environmental factors affecting seed germination. The bHLH transcription factor PIL5 (PHYTOCHROME INTERACTING FACTOR 3-LIKE 5) is the master repressor of...
