Abstract excerpt
Flowering time is regulated by both external environmental cues and internal factors. CCA1(CIRCADIAN CLOCK ASSOCIATED 1) is a core component of the plant circadian clock. While previous studies have implicated CCA1 in flowering regulation, its underlying mechanism has remained incompletely characterized. Here, we demonstrate that CCA1 physically interacts with RGL1(RGA-LIKE 1), a key repressor in the gibberellin...
