Figure 6.
Differential gene expression (A) between three subgenomes and (B) between different copy genes. Expressed genes were collected into lowly (≤ 5), medium (5 < RPKM ≤ 50) and highly (> 50) groups according to RPKM value. Superscript a, b, c indicated the significance of gene expression level with different copies or within different subgenomes.
