  2. Epigenetics – Stable, but expression-related changes in gene function • Methylation of DNA & Histones is involved in epigenetic transcriptional regulation • Correlation between DNA methylation and histone modification • Correlation between gene expression changes and DNA Methylation • Transposable elements are regulated by DNA Methylation • Correlation between DNA Methylation and TE transposition • How is DNA methylation mediated? • Enzymology known • Transposable elements part of repeat-associated/heterochromatic DNA in the genome • Repeat associated DNA methylation controls “transposase” function that mediates transposition, and thus, epigenetic “inheritance”

  3. Plant Biotic and Abiotic Stress Responses • Old time work • Epigenetic stuff • State of the Art
