Title Genome-wide profiling of nucleosomes (MNase-seq), total H3, H3K4me2, H3K4me3 and H3K36me3 (native ChIP-seq) in wild-type, fpa mutant and bdrs triple mutant
Organism Arabidopsis thaliana
Experiment type Genome binding/occupancy profiling by high throughput sequencing
Summary We used an MNase digestion of chromatin from Arabidopsis seedlings, combined or not with ChIP (native ChIP), to analyze by high-throughput sequencing the genome-wide profiles of nucleosomes (MNase-seq), and of total H3, H3K4me2, H3K4me3 and H3K36me3 (native ChIPs) in wild-type (Col-0), fpa mutant (fpa/AT2G43410, line fpa-7) and a triple mutant of all three BDR proteins (bdrs: cross of bdr1/AT5G25520 mutant SALK_142108C, bdr2/AT5G11430 mutant CS852350 and bdr3/AT2G25640 mutant SALK_059905). We found that BDR proteins occupy regions of low nucleosome density. We also observed that genes upregulated in bdrs triple mutant display high levels of RNA polymerase II on their gene bodies but low levels of H3K4me3 and H3K36me3 in wild-type seedlings. For genes with the highest levels of BDR occupancy in wild-type, increased mRNA expression in bdrs mutant is associated with reduced RNA polymerase II density profile and increased H3K4me3 and H3K36me3 levels.
Overall design Genome-wide profiles using native (non crosslinked) chromatin from 8-day old seedlings of nucleosomes (MNase-seq), total H3, H3K4me2, H3K4me3 and H3K36me3 (native ChIP) in wild-type, fpa single mutant (fpa-7) or bdrs triple mutant were generated by deep sequencing on an Illumina NextSeq500. MNase-seq corresponds to the input chromatin sample used for the immunoprecipitation.
