Sequence characteristics and conserved amino acids organization of the HvbHLHs. (a): Sequence logo of the HvbHLH domain by WEBLOGO. The H9, E13 and R16 amino acids in the basic domain are important for DNA binding as indicated by stars. Amino acids are vital for dimerization of the helix-loop-helix domain as indicated by arrows. (b): Distribution of amino acids in the bHLH consensus motif among HvbHLHs. The numbers of horizontal ordinate refer to the positions of the residues in the alignments of the studies.
