In a recent study, Okada et al. screened a library created in the CopyControl™ BAC Cloning Kit (Hind III cloning-ready vector) to study the mechanics of self-incompatibility (inhibiting self-fertilization) in the Japanese pear (Pyrus pyrifolia). The work focused on a DNA contig that contained a 649-kb region around the S-RNase genes. After creation of the BAC library, the selected clones were sequenced using standard ABI BigDye 3.1 sequencing techniques and “old-fashioned” chromosome walking. However, BAC library screening services are increasing turning to next-generation sequencing technologies, due to the ease of rapidly generating large amounts of sequence data with better depth and coverage than traditional Sanger sequencing.
