From: Genome-wide identification and expression analysis of DREB family genes in cotton
Phylogenetic relationships, protein motif analysis, cis-acting element, and gene structure of DREB genes in A G. barbadense, B G. hirsutum, C G. arboretum, and D G. raimondii. The phylogenetic tree was constructed with maximum likelihood method, and DREB proteins were classified into three subgroups (I-III) for each species. Conserved motifs of DREB proteins were identified, and 10 predicted motifs were represented by distinct colored boxes, in which the black lines indicated non-conserved regions. Seventeen cis-acting elements were detected in each species, in which they are represented by distinct colored boxes. Gene structure was analyzed, and green and orange boxes represented untranslated region (UTR) and coding sequence (CDS)
