Abstract excerpt
Covalent modifications of histone-tail amino acid residues communicate information via a specific 'histone code'. Here, we report histone H3-tail lysine methylation profiles of several Arabidopsis genes in correlation with their transcriptional activity and the input of the epigenetic factor ARABIDOPSIS HOMOLOG OF TRITHORAX (ATX1) at ATX1-regulated loci. By chromatin immunoprecipitation (ChIP) assays, we compared...
