The PacBio libraries were constructed using approximately 10 µg of genomic V. dahliae DNA that was mechanically sheared to a size of ~22 kb, using g-TUBES (Covaris, Inc., Woburn, MA) according the manufacturer’s instructions. PacBio SMRTbell libraries were prepared by ligation of hairpin adaptors at both ends of the DNA fragment (52 (link)) using the PacBio DNA template preparation kit 2.0 (Pacific Biosciences of California, Inc., Menlo Park, CA) for SMRT sequencing on the PacBio RS II machine (Pacific Biosciences of California, Inc.) according to the manufacturer’s instructions. Libraries were purified using Agencourt AMPure beads (Beckman Coulter, Inc., Brea, CA) to remove short inserts of <1.5 kb. Libraries were size selected using the BluePippin preparation system (Sage Science, Beverly, MA) with a minimum cutoff of 7 kb. The sheared DNA and final library were characterized for size distribution using an Agilent Bioanalyzer 2100 (Agilent Technology, Inc., Santa Clara, CA) along with a DNA12000 chip (Agilent Technology, Inc.).
