PLANT BRASSINOSTEROID SENSITIVITY-RELATED GENE AND USE OF THE SAME

摘要

A dwarf rice mutant d61 is obtained and a gene (OsBRI1) corresponding to the d61 locus is isolated. OsBRI1 enhances the brasinosteroid-sensitivity of plants and exerts its function in the growth and development processes of rice, for example, internode elongation via the induction of the elongation of internode cells and bending of lamina joints. Rice transformants with modifications in the phenotype are constructed by transferring the antisense strand or dominant negative of OsBRI1.
