Analysis of conserved motifs, protein domains, and GpbHLH gene structures based on the phylogenetic relationships. A The phylogenetic tree of 111 GpbHLHs. B Conserved domains were identified in GpbHLH proteins, and their distributions were visualized using the TB tools software. C The conserved motifs distribution of GpbHLH proteins. The best matched sequences of each conserved motifs were provided in Supplementary Table S3. D Gene structure of GpbHLH genes. Green rectangles and yellow rectangles indicate the untranslated regions (UTRs) and exons, respectively. Introns are presented by black lines. The scale bar is indicated at the bottom of the diagram
