Meiotic recombination initiation hotspots in Arabidopsis genes and transposons (H3K4m3 ChIP-seq). Meiotic recombination initiation hotspots in Arabidopsis genes and transposons (H3K4m3 ChIP-seq)

To investigate the relationship between meiotic recombination initiation and H3K4m3 in Arabidopsis, we generated and sequenced H3K4m3 ChIP libraries from meiotic stage floral buds in wild type, arp6 and met1. To produce high-resolution of H3K4m3 mapping, we used micrococcal nuclease (MNase) to digest chromatins that were cross-linked by formaldehyde for ChIP. This experiment provides for H3K4m3 maps with the resolution of mononucleosomal DNA level (~150 bp).
