Therefore, we hypothesized that fatty acid profiles in pigeon muscle are regulated by gene co-expression modules identifiable via weighted gene co-expression network analysis (WGCNA). To test this, we analyzed pectoral muscles from pigeons at five developmental stages (28 days to 48 months) using gas chromatography–mass spectrometry (GC–MS) and transcriptomic sequencing.

In this study, calcium sulfide (CaS) was used as a slow-release H₂S donor that gradually releases H₂S through reactions with airborne moisture and carbon dioxide to treat bananas. CaS treatment significantly downregulated key ethylene biosynthetic genes and corresponding enzymes (ACO and ACS), thereby reducing ethylene production.
