PLANT BIOLOGY BKI1 Keeps the Receptor Quiet

The plant steroid hormone, brassinosteroid, is perceived at the cell membrane through interaction with a membrane-bound receptor. Subsequent signaling events carry the signal to the nucleus. Wang and Chory now clarify a new interacting partner that regulates the receptivity of the receptor at the cell membrane. BKI1 keeps the signaling pathway relatively quiet until the brassinosteroid appears and activates the system.
