MGIseq of Spiraea crenata
We randomly sheared 500 ng of genomic DNA using the Bioruptor Plus (Diagenode, Lige, Belgium) and adenylated the 3 ends of the 200-500 base pair (bp) long fragments after size selection using magnetic beads (SPRI SureSelect Kit, Beckman Coulter, Brea, CA, USA). We then prepared the sequencing library using MGIEasy Universal DNA Library Prep Set v1.0 (MGI Tech Co., Ltd., Shenzhen, China) according to the manufacturers instructions. We sequenced the library on a DNBSEQ-G400RS platform (FCL PE150).
