| Research Abstract |
This study established a novel pathway via early C-2 hydroxylation in brassinosteroid (BR) biosynthesis as well as new functions of UGT73C6 and rice CYP734As in BR catabolism. ASKθoverexpressors displayed a bri1-like phenotype, and accumulated high levels of BRs. ASKθwas shown to function as a negative regulator in BR signaling. Through the analysis of BR-related mutants such as tcp1-1D and ces-D, we identified TCP1 and CESTA as transcription factors that positively regulate BR biosynthesis.
