22(S),23(S)-Homobrassinolide

개요22(S),23(S)-Homobrassinolide are steroidal hormones belonging to the cyclopentane polyhydrophenanthrene class. Unlike animal steroid hormones, they exert their effects not through nuclear receptors but via surface receptors on cell membranes. Brassinosterols were first discovered by Michel in 1970. He extracted a highly active substance from rapeseed pollen that promoted plant stem elongation and cell division, naming it brassinosteroid (Brassins). Given that even minute concentrations of brassinosteroid strongly induce growth and differentiation, and through subsequent molecular genetic studies in Arabidopsis thaliana, it was demonstrated that brassinosteroid functions as a plant hormone.

용도22(S),23(S)-Homobrassinolide has been used as a brassinosteroid supplement:to study its effects on DNA methylation, callus growth and regeneration in barley.to study its effects on cell elongation in Arabidopsis thaliana.to study its effects on cell division, root germination and anti-oxidant system enzymes in barley.
