Figure 7From: Genome-wide identification and characterization of the bHLH gene family in tomato Phylogenetic relationships in the vascular plants, moss, and algaes. Maximum likelihood analysis of 696 plant bHLHs show as cladogram, and was rooted with a node of red algae protein. The gray balloons delineate the 18 subfamilies of bHLH proteins. Colored dots symbolize the species to which the bHLH proteins in each group belong (yellow: Oryza sativa [monocot]; red: Solanum lycopersicum [eudicot]; green: Arabidopsis thaliana [eudicot]; light-blue: Selaginella moellendorffii [lycophyte]; purple: Physcomitrella patens [moss]; black: Volvox carteri, Chlamydomonas reinhardtii, and Cyanidioschyzon merolae [chlorophytes and red algae]).
