They regulate multiple physiological functions including seed germination, cell elongation, cell division, senescence, vascular-differentiation, reproduction, root development, photomorphogenesis, and also respond to various biotic and abiotic stresses.

BR-deficient mutants exhibits extreme dwarfism, altered leaf morphology, abnormal vascular development, delayed flowering and senescence, and reduced male fertility.

Bioactive brassinosteroid levels are also modulated by a variety of inactivation or catabolic reactions, including epimerization, oxidation, hydroxylation, sulfonation, and conjugation to glucose or lipids.

Active brassinosteroids are also regulated by brassinosteroid-dependent negative feedback mechanisms attenuation which is brought about by the downregulation of brassinosteroid biosynthetic genes and the upregulation of genes involved in brassinosteroid catabolism.
