Hi-C sequencing assembly
For generating a chromosomal level assembly of the genome, we took advantage of sequencing data from the Hi-C library. The Hi-C library was sequenced on the Illumina NanoSeq 6000 (Illumina, CA, USA) and generated 495 million Hi-C read pairs. After filtering out low-quality sequences (quality scores  15), adaptor sequences and sequences shorter than 30 bp by fastp and the clean paired-end reads were mapped to the draft assembled sequence using bowtie2 (v.2.3.2) to get the unique mapped paired-end reads.
