Structural variation affects many genes. The average log2(other/B73) is plotted for all 2767 genes on chromosome 6 (A) or for 293 genes within a 20-Mb region of chromosome 1 (B) for eight genotypes. (Blue data points) UpCNV with more copies in the other inbred line relative to B73; (red data points) genes with significantly lower signal in the other line relative to B73 and are examples of DownCNV or PAV; (red arrows) several multigene structural variants that are observed in multiple genotypes; (black arrows) the position of several single gene structural variants that are observed in multiple genotypes.
