Schematic diagrams for motif compositions of GmBBX proteins and their gene structures. A Motif compositions of the 59 GmBBX proteins. The online software, MEME, was used with the maximum number of motifs being set at 20. The left panel represents phylogenetic tree of GmBBXs, and the Roman numerals (I-V) indicate the five groups; the right panel refers to the schematic diagram of motif compositions, and each motif is represented by a number in a colored box; the sequence logos of 20 motifs were shown in the right-most position. B Exon-intron structures of GmBBX genes in soybean. Exons and UTR are represented by yellow boxes and green boxes, respectively, and grey lines between exons represents introns. The sequence lengths of each protein and gene are represented by grey bars at the bottom
