Construction, complete sequence, and annotation of a BAC contig covering the silkworm chorion locus.

ABSTRACT: The silkmoth chorion was studied extensively by F.C. Kafatos' group for almost 40 years. However, the complete structure of the chorion locus was not obtained in the genome sequence of Bombyx mori published in 2008 due to repetitive sequences, resulting in gaps and an incomplete view of the locus. To obtain the complete sequence of the chorion locus, expressed sequence tags (ESTs) derived from follicular epithelium cells were used as probes to screen a bacterial artificial chromosome (BAC) library. Seven BACs were selected to construct a contig which covered the whole chorion locus. By Sanger sequencing, we successfully obtained complete sequences of the chorion locus spanning 871,711 base pairs on chromosome 2, where we annotated 127 chorion genes. The dataset reported here will recruit m
