Heritable epigenetic variation among maize inbreds

ABSTRACT: Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. Methylation of cytosine residues provides a mechanism for the inheritance of epigenetic information. We have profiled the distribution of DNA methylation in the large, complex genome of Zea mays (ssp. mays). DNA methylation levels are higher near the centromeres and are generally inversely correlated with recombination and gene expression levels. However, genes that are located in non-syntenic genomic positions relative to species related closely to maize exhibit higher levels of DNA methylation independent of expression state. A comparison of the DNA methylation levels in two different inbred genotypes, B73 and Mo17, allowed for the identification of approximately 700 differenti
