genomes sequencing were performed with a pair and reads library with an average insert size (125 bp + 125 bp) on a HiSeq 2500 sequencer (Illumina, CA, USA). The paired-end raw reads were corrected as the clean reads utilizing FASTX-Toolkit (http://hannonlab.cshl.edu/fastx_toolkit/) and then the corrected clean reads were assembled using the software velvet V1.2.03.
