Improving silkworm genome annotation using a proteogenomics approach


ABSTRACT: We collected a total of 9.8 million mass spectra data generated in the laboratory from the proteomics analyses of different silkworm tissues, including the posterior silk gland 29, middle silk gland 30, ovary and testis 31, head 32, brain, prothoracic glands, subesophageal ganglion 33, hemolymph 34, fat body 35 and embryo 36,37 of domestic silkworm, and the posterior silk gland of wild silkworm 38.

The silkworm genome has been deeply sequenced and assembled, but accurate genome annotation, which is important for modern biological research, remains far from complete. To improve silkworm genome annotation, we carried out a proteogenomics analysis using 9.8 million mass spectra collected from different tissues and developmental stages of the silkworm. The results confirmed the translational products of 4307 existing gene models and identified 1701 novel genome search-specific peptides (GSSPs)  ...[more]
