Background The essential helix-loop-helix (bHLH) proteins are a superfamily of transcription factors that can bind to specific DNA target sites. and the expected DNA binding activities within subfamilies. Distribution mapping results demonstrated bHLH genes had been localized for the 12 tomato chromosomes. Among the 152 bHLH genes through the tomato genome, 96 bHLH genes had… Continue reading Background The essential helix-loop-helix (bHLH) proteins are a superfamily of transcription
