genomic data
Genomic DNA of M. mellinum was extracted using the Qiagen DNeasy kit (Qiagen, Hilden, Germany), the purified was fragmented and used to construct short-insert libraries (insert size 300 bp) using Illumina TruSeq Nano DNA Library Preparation Kit, and then sequenced on the Illumina HiSeq 4000 platform using 150 bp paired-end mode.
