Article Title: Stable Patterns of CENH3 Occupancy Through Maize Lineages Containing Genetically Similar Centromeres
Figure Lengend Snippet: Genes and repetitive DNA in centromeres. (A) Overlap between CENH3 enrichment and genetic elements. Within the centromere, we assigned each 20-kb locus into one of two categories, “low CENH3 loci” and “high CENH3 loci,” based on whether it exhibited less than or greater than the median CENH3 enrichment. Results are shown for three methods of measuring CENH3 enrichment. The first two are relative to a total nucleosome control produced by MNase digestion of total chromatin and relative to a randomly sheared naked DNA control produced by NEBNext dsDNA Fragmentase ( Gent et al. 2014 ). In both cases, only uniquely mapping reads were considered. In the third method, no control was used, and enrichment was defined by raw read counts, including nonuniquely mapping reads. Errors bars are standard errors of the means for each set of loci. (B) Comparison of genetic elements in centromeric 20-kb loci and whole-genome 20-kb loci, but without regard to relative CENH3 enrichment within centromeres
