Analysis of conserved motifs, gene structures and protein domain in the phylogenetic tree of 87 PsbZIP genes. A A phylogenetic tree was constructed using the NJ method. B Exons and introns are shown as yellow rectangles and gray lines, respectively. The bZIP domain region is clearly marked. 0, 1, and 2 indicate exon phase. C Ten conserved motifs predicted in bZIP proteins are shown as differently colored boxes. D bZIP protein conserved domains are shown as green boxes
