From: Comparative functional genomics analysis of bHLH gene family in rice, maize and wheat
Phylogenetic relationship among Arabidopsis, rice, maize, and wheat bHLH proteins. An unrooted cladogram shows the phylogenetic relationships among 1154 bHLHs from Arabidopsis thaliana (At), Oryza sativa (Os), Zea mays (Zm) and Triticum aestivum (Ta). The blue balloons delineate the 36 subfamilies of bHLH proteins. Colored lines symbolize the species to which the proteins belong (red: Arabidopsis thaliana; purple: Oryza sativa; blue: Zea mays; green: Triticum aestivum). A full tree with protein names, proportional branch lengths, and clade support values is given in Additional file 5: Figure S2
