Predicted exon-intron structures of walnut LACs and conserved motifs of walnut LAC protein. A. The phylogenetic tree was constructed based on the full-length protein sequences of 37 walnut LAC proteins using MEGA V7.0.21 software. B. Location of conserved motifs in walnut JrLAC proteins. Motifs, 1–12, are displayed by differently colored boxes. C. Exon-intron structure of walnut LAC genes. The exons and introns are indicated by yellow boxes and single lines, respectively
