Collinearity relationships of SsR2R3-MYB genes on the S. spontaneum genome. SsR2R3-MYB collinear gene pairs were mapped to their respective locus in the S. spontaneum genome in a circular diagram. Genes located on the same chromosome (e.g., Chr1, Chr2, Chr3, Chr4, Chr5, Chr6, Chr7, Chr8) shared one line, and the inter-chromosomal collinear genes pairs were linked with the former linear color
