General description

Brassinolide is a plant growth hormone and the most biologically active brassinosteroid (BR). It has been implicated in Auxin signaling. It has also been used for studying plant biosynthetic pathways. Brassinolide might also regulate water-transport properties of cell membranes in Arabidopsis thaliana.

Application

Brassinolide has been used as a plant growth hormone.
