Recent studies of the brassinosteroid-deficient mutants have revealed that brassinosteroid plays essential roles to control plant growth and development, such as cell elongation, division and photomorphogenesis. However, its regulatory mechanisms and signal transduction pathway are still under unclear. To provide insight into the signaling pathway responsible for the induction of gene expression by Brassinolide, we examined the effects of Brassiolide on Brassinosteroid-inducible genes using the protein kinase inhibitor staurosporin or Brassinoseroid-Insensitive 1 mutant. These studies revealed that Brassinosteroid inducible-gene expression was mediated by at least two distinct pathways, one of that inhibited by protein kinase inhibitor staurosporin or the other is not.
