Genome-wide landscape of genetic variation in Sorghum bicolor. Gene density of chromosomes is visualized by line darkness; the more genes on a chromosome region, the darker the color. The purple and blue colors in the CNV ring represent gain and loss of copy number variation, respectively. For PAVs, the green color stands for the absence of variation, whereas pink for the presence of variation.
