Fig. 2: Genome structure and gene collinearity.

From: A chromosome-scale assembly of the quinoa genome provides insights into the structure and dynamics of its subgenomes

Fig. 2

Each colored link represents a block of collinear genes between orthologous chromosomes; black links represent collinearity between non-orthologous chromosomes. a Structure of quinoa chromosomes and collinearity relationships between quinoa subgenomes. From outside to inside, tracks represent chromosome names, positions (Mb), chromosome ideograms (blue, A subgenome; green, B subgenome), gene density in 1-Mb windows (with lowest to highest density expressed as a gradient of intensity from white to red), and TE density in 1-Mb windows (with lowest to highest density expressed as a gradient of intensity from white to purple). b, c Chromosome structure and collinearity between the quinoa A subgenome and C. pallidicaule (b) and between quinoa B subgenome and C. suecicum (c). From outside to inside, tracks represent chromosome names, positions (Mb), chromosome ideograms (blue, A genomes; green, B genomes), C. suecicum short-reads mapping rate in 1-Mb windows, and C. pallidicaule short-reads mapping rate in 1-Mb windows.
