Fig. 3.

Phylogenetic relationships and conserved motif distributions of the DREB (a) and ERF (b) subfamilies of proteins. a TFs from group I to group IV were used to construct a phylogenetic tree. b TFs from group V to group IX, group X and group XI were separately used to construct a phylogenetic tree. A phylogenetic tree was constructed using the neighbour-joining method. Different coloured boxes indicate different motifs. Box length was equivalent to motif length. Different color shapes indicated different groups in the phylogeny of CaERFs associated with Arabidopsis
