Total genomic DNA was extracted from the fresh leaves of P. bellatulum using the DNeasy Plant Mini Kit (Qiagen, Valencia, CA, USA). After DNA isolation, 1g of purified DNA was fragmented and used to construct short-insert libraries (insert size ~350bp) according to the manufacturers instructions (BGISEQ) detailed in the previous literature (Huang et al. 2017). Then DNA libraries were sequenced by Hefei Bio&Data Biotechnologies Inc. (Hefei, China) on the BGISEQ-500 platform with PE150 read lengths.
