Extended Data Fig. 7: Allelic H3K27me3 enrichment of MEGs.
From: Multilayered epigenetic control of persistent and stage-specific imprinted genes in rice endosperm
a, Metagene plots showing allelic Z-scores for H3K27me3 levels in MEGs. Differently colored lines represent different classes of genes: gray, all genes; blue, persistent imprinted genes; green, stage-specific imprinted genes. Solid lines indicate paternal alleles, and broken lines indicate maternal alleles. b, Differences in average allelic Z-scored H3K27me3 levels between paternal and maternal alleles (maternal – paternal). All data are from eight independent crosses, each consisting of two biological replicates of two combinations of reciprocal crosses between NIP-KAS and NIP-9311. The box plots show the median (line within the box), the lower and upper quartiles (box), margined by the largest and smallest data points that are still within the interval of 1.5 times the interquartile range from the box (whiskers); outliers are not shown. Significant differences were not detected in MEGs. c, Proportions of different epigenetic marks in the gene body region of each class of MEGs. Different colors indicate different combinations of epigenetic marks. Significant enrichment for combinations of epigenetic marks was tested using a hypergeometric test. P values were adjustment by Bonferroni methods, *P < 1.0E-08.
