The male
P. simonii seeds provided by Luoning Bureau of Forest, Henan Province, China and planted at the Xiashu Forest Farm of Nanjing Forestry University, Jurong, Jiangsu Province, China. Fresh leaves were collected and immediately frozen in liquid nitrogen, followed by preserving the leaves at –80°C in the laboratory prior to DNA extraction. The total genomic DNA was extracted from leaves using the CTAB protocol (Arseneau et al., 2017 (
link)), and a library with an insert size of 20 kb was constructed using a BluePippin DNA size selection instrument (Sage Science, Beverly, MA, United States) with a lower size limit of 10 kb. The prepared library was sequenced on the
PacBio Sequel platform (Pacific Biosciences, United States) at Frasergen Technologies Corporation, Wuhan, China. After the removal of adapter sequences using SMRTlink (v7.0.1
2), the remaining sequences were used for genome assembly and error correction. Additionally, to collect the contigs assembled by the PacBio sequencing data, we also sequenced the same genomic DNA afore-described on the
Illumina HiSeq 2000 sequencing platform at Biomarker Technologies Corporation, Beijing, China.
