Ectopic expression of OsLFL1 in rice represses Ehd1 by binding on its promoter.

Abstract

B3 domain was identified as a novel DNA-binding motif specific to higher plant species. The B3 proteins play important roles in plant development. In the mutant W378, the mutant gene coding OsLFL1, a putative B3 transcription factor gene, was ectopically expressed. In this study, it was found that the flowering promoting gene Ehd1 and its putative downstream genes were all repressed by OsLFL1. Electrophoretic mobility shift assays (EMSA) and chromatin immunoprecipitation (ChIP) analyses suggest that OsLFL1 binds to the RY cis-elements (CATGCATG) in the promoter of the Ehd1 gene. Thus, ectopically expressed OsLFL1 might repress Ehd1 via binding directly to the RY cis-elements in its promoter.
