【 摘 要 】
Brassinosteroids (BRs) are plant steroids essential for the normal growth and development, which carry an oxygen moiety at C-3 and additional ones at one or more of the C-2, C-6, C-22 and C-23 carbon atoms. In the past few years, application of molecular genetics allowed significant progress on the understanding of the BRs biosynthetic pathway regulation and on the identification of several components of their signal transduction pathway, as well. Search in eletronic databases show dozens of records for brassinosteroid-related genes for the last twelve months, demonstrating the big efforts being carried out in this field. This review highlights the recent advances on the characterization of genes and mutations that are helping to unravel the molecular mechanisms involved in the BRs synthesis/metabolism, perception and response, with especial emphasis on their role in plant cell elongation. Aspects of the involvement of BRs on the regulation of cell cycle-controlling proteins are discussed as well.
