Total DNAs were extracted from with DNeasy PowerSoil Pro Kit (QIAGEN, GER) following the standard protocols. For library construction, total DNA was randomly fragmented to an average size of 500 bp. Paired-end Illumina libraries were prepared using a NovaSeq 6000 S4 Reagent Kit (San Diego, CA, USA), and sequencing was performed using Illumina NovaSeq 6000 platform (150 bp paired-end) (Illumina Inc., San Diego, CA, USA).
