Figure 3: — Genome evolution analysis of C. heterophylla. (A) Summary of gene family clustering of C. heterophylla and 7 related species. Single-copy orthologs: 1-copy genes in ortholog group. Multiple-copy orthologs: multiple genes in ortholog group. Unique orthologs: species-specific genes. Other orthologs: the rest of the clustered genes. Uncluster genes: number of genes out of cluster. (B) Phylogenetic relationship and divergence time estimation. The O. sativa was considered as outgroup in phylogenetic tree construction. The red dots indicate the fossil correction time of O. sativa vs P. trichocarpa (152–160 Mya) and crown nodes of family Betulaceae (51.2–66.7 Mya), respectively.
