Conserved motifs and gene structures of GmPKs. a Phylogenetic tree based on protein sequences of PK genes in soybean. b Conserved motifs of GmPKs. The details of the motif were shown in Figure S2. c The gene structures of GmPK genes. CDS, introns, and untranslated regions (UTRs) are indicated by yellow boxes, black lines, and green boxes, respectively
