DIVARICATA1 Promotes Leaf Degreening and Senescence in Arabidopsis
-kaurene oxidase (KO1) both in vitro and in vivo. The promoted senescence phenotype in DIV1-overexpression lines was rescued by treatment with paclobutrazol (PAC), a GA biosynthesis inhibitor. In summary, our findings reveal a dual mechanism whereby DIV1 integrates the GA pathway and NAC-mediated transcription to regulate leaf senescence. This work provides new insights into the coordination between MYB and NAC TFs during hormone-mediated senescence.
