Title:  Contribution of Genetic and Epigenetic Variation to Diversity in Maize

Geneticists often think of different individuals of the same species as having highly similar genomes. However, there is evidence that the structure, and modifications, of the genomes of different individuals can highly vary. I will describe evidence that shows the dynamic nature of the maize genome and extensive variation in gene content among different maize genotypes. I will also describe the studies of several chromatin modifications in maize including DNA methylation and histone methylation (H3K27me3). There is evidence that variation in these chromatin modifications is controlled by both genetic and epigenetic factors. We have been studying the stability and heritability of these marks to understand how the epigenome is inherited and how it is influenced by environmental factors.
