Brassinazole has been used in phenotype analyses to detect morphological changes in G-protein ? subunit agb1 mutants.
Biochem/physiol Actions
Brassinazole is an inhibitor of the biosynthesis of brassinosteroids, steroid hormones essential for plant growth and development. It has been used to study brassinosteroids function.
Brassinazole induces dwarfism and morphological changes in Arabidopsis, which results in similarity with brassinosteroid deficient mutants. These changes were neutralized by brassinolide treatment, indicating that brassinazole leads to brassinolide deficiency in Arabidopsis.
