Abstract excerpt

Catabolism of brassinosteroids regulates the endogenous level of bioactive brassinosteroids. In Arabidopsis thaliana, bioactive brassinosteroids such as castasterone (CS) and brassinolide (BL) are inactivated mainly by two cytochrome P450 monooxygenases, CYP734A1/BAS1 and CYP72C1/SOB7/CHI2/SHK1; CYP734A1/BAS1 inactivates CS and BL by means of C-26 hydroxylation. Here, we characterized CYP734A orthologs from Oryza...
