H3K4me3-ChIP-seq in Arabidopsis thaliana Col and hcr2 mutant

Col and hcr2 mutant from seedling and bud sample were harvested. Nuclei extracted using Honda buffer. Cross-linked chromatin was fragmented with mirococcal nuclease (MNase, NEB M0247S). After fragmentation, fragmented chromatin was incubated with H3K4me3 antibody (AbCam ab8580). TruSeq Prep Kit v2 (Illumina) were used for library construction.
