title: WGS of Rosa beggeriana: GXF19018-3 sample
design: Genomic DNA extracted from silica-dried Rosa leaf tissue using a CTAB protocol was processed with the BGI Optimal DNA Library Prep Kit: genomic DNA fragmentation, magnetic-bead size selection, end repair, 3 A-tailing, adaptor ligation and PCR amplification; double-stranded libraries were denatured, circularised, residual linear DNA removed, and phi29 rolling-circle amplification generated DNA nanoballs (~300 copies) that were loaded onto a patterned nanoarray and sequenced on a DNBSEQ-T7 (BGI-Shenzhen, China) to produce 2  150 bp paired-end reads; raw reads were filtered and quality-controlled using SOAPnuke v2.2.6 with parameters as follows: -n 0.001 -l 10 -q 0.5 -Q 2.
