design: Libraries (20-kb inserts) were sequenced using a single molecule real-time (SMRT) PacBio system. Libraries were prepared using a standard PacBio library preparation protocol (Pacific Biosciences, Menlo Park, CA, USA) followed by damage and end repair, blunt-end adaptor ligation, and SMRTbell library quality assessment (McCarthy, 2010). One SMRT cell was run for genome sequencing on the PacBio RS II sequencing platform.
