Abstract: Upon perception of BRs, signals of BRI1/BAK1 receptor complex are transmitted through a phosphorylation cascade that includes both changes in gene expression and rapid growth induction responses that involve the V-ATPase.These pathways act separately to affect cell expansion processes.This review focuses on recent progresses in the studies of the gene expression regulation by BRs, BRs signaling and cell expansion in plant, and discusses the unsolved issues.

Key words: Brassinosteroids, signaling, cell expansion, gene expression
