Fig. 2From: Genome-wide identification and characterization of TALE superfamily genes in cotton reveals their functions in regulating secondary cell wall biosynthesisPhylogenetic analysis and classification of BEL1-like and KNOX family genes in four Gossypium species and Arabidopsis thaliana. a Phylogenetic analysis and classification of BEL1-like family genes. b Phylogenetic and classification analysis of KNOX family genes. The subfamilies of the BEL1-like and KNOX members are represented by different colors. Numbers on the branches are bootstrap proportions of 1000 replicates. Ga, Gossypium arboreum; Gr, Gossypium raimondii; Gh, Gossypium hirsutum; Gb, Gossypium barbadense; At, Arabidopsis thaliana. The phylogenetic tree was constructed by MEGA 6.0 software using the neighbor-joining (NJ) methodBack to article page
