Description (Rac)-Brassinazole, triazole-type compound, is a brassinosteroid (BR) biosynthesis inhibitor. (Rac)-Brassinazole increases inhibition of CYP90B in BR biosynthesis[1][2]
Related Catalog
In Vitro (Rac)-Brassinazole (compound 5) does not retard rice stem elongation, and retardation is recovered by the addition of gibberellin (GA3), suggesting that such retardation is due to the inhibition of gibberellin biosynthesis[1]. (Rac)-Brassinazol (compound 31) results in a reduction in the effect on AtKO in gibberellin (GA) biosynthesis[2].
