The identification of parent-of-origin-dependent nucleosomes. (A) Pipeline for identifying parent-of-origin-dependent nucleosomes. (B) Allele-specific analysis of nucleosomes in maize endosperm. The x-axis and y-axis represent the log2 of maternal reads divided by paternal reads for the allelically analyzed nucleosomes in endosperm from BM (blue lines) and MB (read lines). (C) Regions around maternal/paternal specifically positioned nucleosomes. Green lines indicate the levels of nucleosomes. The black, light blue, and pink lines indicate the center position of endosperm nucleosomes, allelically analyzed nucleosomes, and high-stringency allele-specific nucleosomes. The percentages of allelic reads of MNase-seq data for specific SNP sites are shown; red lines represent the paternal alleles, and blue lines represent the maternal alleles.
