This study used multiomics to analyze Bombyx mori (silkworm) cocoon shells, revealing insights into species diversification. The findings offer a foundation for future research on silkworm cocoon shell applications.

Area of Science:

  • Zoology
  • Genomics
  • Biochemistry

Background:

  • Recent genomic findings highlight variability in Bombyx mori ancestry and cocoon shell color.
  • Historical and contemporary silkworm populations present an opportunity to study human-driven diversification.

Purpose of the Study:

  • To investigate the human-driven introduction and diversification of Bombyx mori in Europe.
  • To characterize the phenomic, proteomic, metabolomic, and lipidomic profiles of Bombyx mori cocoon shells.

Main Methods:

  • Combined phenomics, proteomics, metabolomics, and lipidomics analyses.
  • Optical and fluorescence imaging of 148 cocoon shells.
  • LC-MS/MS analysis of 80 cocoon shell samples.
  • Data validation using dimensionality reduction, clustering algorithms, and historical archives.
