Chromatin was extracted from Arabidopsis seedlings. 100μg of Arabidopsis chromatin was immunoprecipiated with an anti-H3K4me3 antibody (Millipore, 07-473). The resulting DNA then was used for library preparation with NEBNext Ultra DNA Library Prep Kit for Illumina (NEB) . The ChIP libraries were sequenced in SE75 mode on a NextSeq500 Illumina machine.
