Relationships of variations in gene expression and histone modifications between organs and between genotypes. (a) Frequencies of concurrence between variations in gene expression and histone modifications between shoots and roots. R, root; S, shoot. Numbers indicate the percentage of differentially modified genes that were also differentially expressed. (b) Correlations between differential gene expression (P<0.01 and fold change >2.0) and histone modifications (P<0.01 and fold change >1.5) between shoots and roots. (c) A typical maize gene showing differential gene expression and epigenetic modifications in shoots and roots. DNA methyl, DNA methylation. (d) Correlations between differential gene expression (P<0.01 and fold change >2.0) and histone modifications (P<0.01 and fold change >1.5) between hybrids and parents.
