Abstract excerpt
Flowering is a crucial developmental process in angiosperms. However, the underlying mechanisms remain to be elucidated. In this study, we identify INDETERMINATE DOMAIN (IDD) transcription factors (TFs), IDD14, IDD15, and IDD16, as redundant negative regulators of flowering time in Arabidopsis. The idd14-1 idd15-5 idd16-1 triple mutant displays early flowering, while the gain-of-function mutation in idd14-1D...
