Figure 4.

Graphical view of syntenic relationship between white clover, red clover, M. truncatula, and L. japonicus. Homologous regions were identified by BLASTX searches with a cutoff E-value ≤ 1e−10. Synteny blocks were defined as the region where three or more conserved homologs were located within a 10-cM region in the white and red clover linkage maps, and a 500-kb DNA stretch in the reference genomes. Syntenic regions between the two clover species and model legumes are connected by colored lines. Line colors represent white clover homeologous linkage groups and red clover linkage groups of orthologous loci. (A) Syntenic relationships between two clover species and M. truncatula. (B) Syntenic relationships between two clover species and L. japonicus.
