HiC reads
We constructed a Hi-C library. Crosslinked and biotin-labeled DNA was obtained using the Arima High Coverage Hi-C Kit (Arima) following the manufacturers instructions for plant leaf tissues. We used the NEBNext Ultra Express DNA Library Prep Kit (New England Biolabs) to build the libraries and sequenced them on a NextSeq 2000 (Illumina) using a P3 Reagent 300 cycles (2 x 150 bp) flow cell (Illumina).
