Study TitleLipidomics Analysis of the Silkworm Cocoon Shell
Study TypeLipidomics
Study SummaryIn this study we conducted lipidomics analyses of historical and contemporary Bombyx mori cocoon shells to case-study the human-driven introduction and diversification of this species in Europe. We employed LC-MS/MS analyses protocols for 80 cocoon shell samples to identify that the cocoon shell of this species contains 981 lipids in 80% of the samples. Our lipidomics datasets provide a valuable foundation for advancing further exploitations of silkworm cocoon shells in multiple scientific perspectives.

Project Title:Multiomics Coalescent Analyses Delineates the Complex Anthropogenic Evolution of Silkworm Races in Europe
Project Type:Metabolomics and Lipidomics
Project Summary:Employing phenomics, proteomics, metabolomics and lipidomics, this study identifies the introduction routes and anthropogenic evolution of European silkworm races, a clade of silkworm races with unresolved and obscure ancestry. Prompted by recent findings on the genomic variability that underlies the ancestry and cocoon shell colour of the silkworm, Bombyx mori, we carried out a large-scale analysis of historical and contemporary cocoon shells of this species. By taking our datasets through a series of dimensionality reduction and clustering algorithms, in conjunction with narratives from historical archives that attest to continuous familial interbreeding and constant influx of silkworm races in Europe, we identify three regional hotspots of diversification of these European silkworm races. Furthermore, and in agreement with recent genomic analyses which show an early evolutionary divergence of European silkworm races, we show that these races exhibit human-driven phenotypic innovations, during their domestication in Europe, caused by continuous familial breeding, selection for a limited number of traits and limited regional segregation. Our multiomics datasets provide a valuable foundation for advancing further exploitations of silkworm cocoon shells and show that the European silkworm races are lineages of races that evolved in Central Asia and the Middle East before arriving in Europe and then continuously interbred and improved through introduction of Chinese and Japanese silkworm races.

Collection:

Collection ID:CO003969
Collection Summary:A set of 80 of the 148 cocoon shell samples were selected for metabolomics and lipidomics analysis. The set of the 80 selected samples is shown in Supplementary File s1. A pilot study was carried out with 4 additional samples to validate every step of the sample analysis and assess its feasibility. The results of the pilot study are not included in the analysis of the 80 samples. A careful selection of the 80 cocoon shell samples was carried out aiming to avoid as much as possible ambiguously-labelled B. mori mutants (see Supplementary File s1) as well as samples with known parental-sibling relationships (i.e. samples 141-147, see Supplementary File s1) that would skew the analysis results. Purposefully, samples of the same name or similar geographic location were used in the analysis to assess the effect of the place of origin and sample freshness on the obtained results.

Sample Preparation:

Sampleprep ID:SP003982
Sampleprep Summary:For biphasic extraction of lipids and polar metabolites, cocoons were cut into small pieces and placed in 5 mL centrifuge tubes. Three (3) mL of MeOH (containing internal standards) were initially added to the cocoon samples. After vortexing and ultrasonic bath extraction for 10 min, 1.8 mL of supernatant were collected and transferred to clean 15 mL centrifuge tubes. Subsequently, 4.5 mL of MTBE were added and the monophasic mixture was vortexed for 60 s and incubated at -20 °C for 20 min. For phase separation, 1.2 mL water were added, followed by another vortexing and incubation step (see previous conditions). The biphasic solvent system was then centrifuged for 15 min at 5000 rpm and 4 °C with a 5810R centrifuge (Eppendorf, Germany). For lipidomics analysis, 4 mL of the upper organic phase were transferred, dried under a stream of nitrogen, and reconstituted in 100 µL IPA:MeOH (50:50, v/v). For metabolomics analysis, 2.4 mL of the lower aqueous phase were transferred, dried under a stream of nitrogen, and reconstituted in 75 µL 80% MeOH (v/v). The final samples were vortexed for 10 min, centrifuged (see previous conditions) and the supernatants were transferred to analytical glass vials for LC-MS/MS analysis.
