Brassinosteroid and systemin: two hormones perceived by the same receptor.
Brassinosteroids, coordinating developmental events, and systemin, inducing systemic wound responses to attacks by insect pests, are newly recognized plant hormones that are perceived by plasma membrane-localized leucine-rich repeat receptor kinases. The recent characterization of the brassinosteroid receptor BRI1 from tomato revealed that this protein is identical to the previously isolated SR160 systemin receptor, strongly suggesting that both brassinosteroid and systemin signalling use the same surface receptor.
