Brassinosteroid Signaling: A Paradigm for Steroid Hormone Signaling from the Cell Surface
Youssef Belkhadir and
Joanne Chory*
Plants use the coordinated action of several small-moleculehormones to grow and develop optimally in response to a changingenvironment. Among these hormones are the brassinosteroids (BRs),the polyhydroxylated steroid hormones of plants. BRs bind asmall family of leucine-rich repeat receptor kinases at thecell surface, thereby initiating an intracellular signal transductioncascade that results in the altered expression of hundreds ofgenes.
