Evolutionary tree, conserved motif compositions, and gene structures of 70 wheat TALE genes. The unrooted neighbor-joining tree was constructed by MEGA7. The 20 motifs were identified by MEME Suite. Different conserved motifs are displayed in different colored boxes. Motif 5 represents KNOX domain, motif 4 represents KNOX domain, motif 6 represents ELK domain, motif 7 represents POX domain, and motif 1 represents HOX domain. The lengths of the exons and introns of each gene are shown proportionally. The yellow boxes represent exons, the black lines represent introns, and the green boxes represent 5′ and 3′ non-coding regions
