Phylogenetic analysis, gene structures and conserved motifs of GmGRFs. a The phylogenetic relationship of GmGRFs. A neighbor-joining phylogenetic tree was constructed by MEGA7.0 software with the Poisson model and 1000 bootstrap replications. b Conserved motif arrangements of GmGRFs. Ten conserved motifs labeled with different colors were found in the GmGRF sequences using the MEME program. Among them, motif 1 and motif 2 are the QLQ and WRC conserved domains. c Exon-intron organizations of GmGRFs. The green boxes represent 5’or 3′ untranslated regions, yellow boxes represent the coding sequences, and black lines represent the introns. The lengths of the exons and introns can be determined by the scale at the bottom
