The Illumina HiSeq X Ten platform was used for genome sequencing (Macrogen Inc., Seoul, Korea). After quality control inspection, library construction was completed as described by Tenea et al. (2020). The raw data obtained from sequencing were processed and used for analysis. FastQC (v0.11.5, http://www.bioinformatics.babraham.ac.uk/projects/fastqc) was used to calculate the overall quality of the reads, the total base, the total reads, the GC content, and the basic statistics. Using SPAdes v3.15.5, different k-mers performed de novo assembly (Prjibelski et al., 2020). The best assembled sequence set was identified, and the best kmer was chosen based on the statistics from the assembly results (contig count, total base of contigs, N50, etc.). BUSCO version 3.0 analysis was carried out to assess the completeness of genome assembly (Simo et al., 2015). By default, analyses were carried out using the bacterial or eukaryote database.  In addition, BLAST analysis was performed to  determine the species to which each scaffold showed similarity.
