Biosynthesis and Metabolism of BrassinosteroidsBrassinosteroids BRs are steroid hormones that regulate the growth and development of biosynthesis of brassinosteroids in plants. Detailed study of the biosynthesis of brassinolide, a C 28 BR, revealed that two parallel routes, the early and late C-6 oxidation pathways, are connected at multiple steps and also are linked to the early C oxidation pathway. Thus, BR biosynthetic pathways are highly networked. Information on enzymes and genes involved in the BR biosynthesis, as well as their regulation, has been obtained using BR-deficient and BR-insensitive mutants. In addition, the biosynthesis of sterols, which were recently recognized not only tren vs anavar fat loss precursors of BRs and membrane constituents, but also as modulators of plant development, is discussed. Various metabolic reactions of BRs including epimerization, oxidation, and conjugation are also summarized. Arabidopsis biosynthesis of brassinosteroids in plants ; Catharanthus roseus ; cytochrome P ; dwarfism ; brassinosteroid-deficient mutant.

However, definitive evidence for their roles in growth and development remained unclear until the recent characterization of BR dwarf mutants isolated from Arabidopsis and other plants. This chapter1 aims to provide a cohesive summary of information about progress made in the molecular genetic characterization of mutants that are defective in sterol and BR biosynthetic pathways.
