a
The genome coverage was calculated via the Coverage/Read Count Calculator (http://apps.bioconnector.virginia.edu/covcalc/) (9).
b
The N50 value is the size of the shortest contig in the set of longest contigs that together cover at least 50% of the total genome size.
c
ncRNA, noncoding RNA; CDS, coding sequence.
