Keyword - Brassinosteroid signaling pathway (KW-1070)


Protein involved in the brassinosteroid (BR) signaling pathway (e.g. transport and signal transduction) that regulates many aspects of plant growth and development including cell expansion and elongation (in association with auxin), vascular differentiation and pollen elongation and pollen tube formation. Also involved in plants protection during chilling and drought stress. BRs are polyhydroxysteroid phytohormones and over 70 BR compounds have been isolated in plants. Brassinolide was the first BR isolated from Brassica napus and remains one of the most active BR.
