Gene structure, motifs, conserved structural domains, compositions and multiple sequence alignment analysis of the PeBBX gene family. a. Intron-exon structure of the PeBBX genes. Yellow boxes represent exons (CDS), black lines represent introns and green boxes represent the 5’ and 3’ untranslated regions. b. Distribution of conserved motifs in PeBBX proteins. The scale bar at the bottom indicates the protein lengths, and sequence logos for each conserved motif are shown on the right. c. Conserved domain predictions for the 27 PeBBX proteins. The length of each protein sequence is represented by the grey bars, and colored boxes represent conserved domains. Green boxes represent CCT domains, light purple boxes indicate BOX1 domains and yellow boxes indicate BOX2 domains. d Multiple sequence alignment of PeBBX protein sequences. The number above the sequence indicates the location of the amino acids in the BBX proteins. The key domains are highlighted, and the domain names are shown at the top of the sequence. Protein sequence names are shown on the left
