Description
In order to analyze the mechanism of brassinosteroid signal transduction in detail, we screened for mutants that showed resistance to brassinosteroid biosynthesis inhibitor Brz220 effects. At first, we identified a semidominant mutant, bil1-1D from EMS-lines. In the Brz 3mM medium, that wild-type plant showed a quite short hypocotyl, but the mutant showed a hypocotyl length as long as the wild type grown on the Brz-unsupplemented medium. The genomic walking results of bzr1-1D(brz-resistant1) revealed that the bil1-1D gene is the just same gene with bzr1-1D, and shared the 88 % identity with bes1(bri1-EMS-suppressor). GFP fusion protein analysis revealed that the plant specific new gene family BZR1/BES1/BIL1 is a key component of the brassinosteroid signaling from the cytosol to nucleus. Analysis of a recessive mutant bil5 was also in progress.
