Fig. 4From: Genome-wide identification, structural and gene expression analysis of the bZIP transcription factor family in sweet potato wild relative Ipomoea trifidaExon-intron structures of ItfbZIP genes. The phylogenetic tree on the left was constructed using MEGA 7 software based on the full length sequences of the ItfbZIP proteins.Yellow rectangles represent exons, blue rectangles represent the untranslated regions, black thin lines represent intronsBack to article page
