Additional file 4: of Genome-wide identification, structural and gene expression analysis of the bZIP transcription factor family in sweet potato wild relative Ipomoea trifida

Figure S1. The sequence alignment of the conserved domain (bZIP domain) in ItbZIP transcription factors. The primary structure of the bZIP domain and highly conserved residues of the bZIP domain consensus sequence [N-X7-R/K-X9-L-X6-L-X6-L] are shown at the top of the picture. Vertical bars with different colors on the left show different subfamilies. The black and gray shades in the picture present the same and similar amino acids, respectively. (XLSX 23 kb)
