Figure S1. Sliding window analysis of Ka/Ks for the orthologous (Pe-Do) and paralogous (Pe-Pe, Do-Do) gene pairs. The window size was 150â bp, and the step size was 9â bp. Figure S2. Gene structures analysis of the BBXs in both D. officinale and P. equestris. The exons and introns are indicated by green rectangles and thin lines, respectively. Figure S3. Comparison of the exon-intron structure between homologous genes (Pe-Pe, Do-Do and Pe-Do). The exons and introns are indicated by green rectangles and thin lines, respectively. Table S1. The 19 DoBBX gene primer sequences. Table S2. The Ka, Ks and Ka/Ks values of orthologous (Pe-Do) and paralogous (Pe-Pe, Do-Do) gene pairs. Table S3. Plant genomes used in this analysis. (DOCX 391 kb)
