Phylogenetic exhibition of gene structures and motif patterns of the identified GmPME members. a Phylogenetic clustering of the GmPME gene members. b Gene structures of GmPME members. Green boxes are untranslated 5′- and 3′- regions; yellow boxes indicate exons; pink boxes represent PME domains; blue boxes suggest PMEI (PME Inhibitor) domains. The gray lines are introns and the numbers (0, 1, 2) indicate intron phases. c Motif patterns of GmPME members. Totally ten distinct MEME-motifs were depicted in different colors, and their sequences were listed in Table S4 (Additional file 4). Besides, the length of relevant gene structures and motif components can be estimated with respective scales at the bottom of panels
