Comparison analysis between C. neglecta and hexaploidy C. sativa. a Collinear synteny blocks between C. neglecta and C. sativa genomes. Synonymous substitutions rate (Ks) from dark to light indicates that genetic divergence from small to large. b Macrosynteny relationship between C. neglecta and C. sativa subgenomes. c Density distributions of the Ks values for homologous genes between C. neglecta and C. sativa subgenomes. d The phylogenetic tree of C. neglecta, C. sativa subgenomes and other closely related plants. The phylogenetic tree is constructed on the basis of 200 single-copy orthologous genes. The values on the branch are the substitutions between species and the nearest ancestor
