The rice Os01g0111500 was reported as OsbHLH125 in 2006 [1] by researchers from the China. It is a member of bHLH transcription factor gene family.

Annotated Information

Gene Symbol

  • Os01g0111500 <=> OsbHLH125


  • The basic/helix-loop-helix (bHLH) transcription factors and their homologs form a large family in plant and animal genomes.
  • rice bHLH proteins can potentially participate in a variety of combinatorial interactions, endowing them with the capacity to regulate a multitude of transcriptional programs.
  • bHLHs represent key regulatory components in transcriptional networks controlling a number of biological processes.
  • Plant bHLHs have been reported to function in light signaling, hormone signaling, wound and drought stress responses, symbiotic ammonium transport, shoot branching, root, fruit and flower development, et al. [1] [2] [3]


  • Similar expression patterns suggest functional conservation between some rice bHLH genes and their close Arabidopsis homologs.


  • The studies of researchers indicate that the ancient bHLH gene family has likely expanded considerably during flowering plant evolution to include many relatively young members, allowing both the conservation and divergence of gene function.
