From: Functional innovations of three chronological mesohexaploid Brassica rapa genomes
Three reconstructed periodical B. rapa genomes based on refined 24 GBs. The left bar represents 0.1 Mb scale of the B. rapa genome and A-X rectangles in the upper part represent 24 genomic blocks (GB). Each chromosome represents three periodical genomic segments distinguished by average synonymous substitution rates of genomic segments (from left, recent, young, and old). The red triangles (►) and arrows (↕) in the left side of the GB map represent newly identified GBs in this study and an inverted order of GBs compared to Cheng et al. (2013) [18], respectively. The structural difference between Cheng et al. (2013) [18] and our map may be arisen by using different version of the B. rapa genome.
