Fig. 5: Comparison of dominance between subgenomes A and B.

a The counts of genes containing each Pfam domain are compared between subgenomes A and B. The Pfam domains are classified into “A ≈ B” (contained gene counts are not significantly different), “A specific” (only contained by subgenome A), “B specific” (only contained by subgenome B), and “A > B” (contained by more genes in subgenome A). b Comparison of chromosomal homologous gene numbers between subgenomes A and B. Scutellaria barbata was used as an outgroup. Wilcoxon test was performed with two-sided alternative hypothesis. c Comparison of Scutellaria barbata homologous gene expression between subgenomes A and B. Genes were classified into three groups according to their total expression value in 18 RNA-seq datasets. The percentage of each group was compared for each chromosome. FPKM is an abbreviation for Fragments Per Kilobase Million. d Comparisons of the expression of genes in each intersubgenome syntenic gene pair. T-test were performed with two-sided alternative hypothesis. Gene pairs are classified into “No significant expression difference”, “A > B” (genes from subgenome A highly expressed than corresponding genes from subgenome B), and “A < B” (genes from subgenome B highly expressed than corresponding genes from subgenome A). e Kernel density plot for the differences in genetic diversity between genes belonging to intersubgenome syntenic gene pairs.
