de novo transcriptome assembly and annotation of Gammarus pulex: a valuable resource for ecotoxicogenomics

This repository contains RNA sequencing (RNA-Seq) data used for the de novo transcriptome assembly of Gammarus pulex, a key freshwater amphipod in ecotoxicology due to its ecological role and sensitivity to pollutants. The transcriptomes were generated from individuals collected at sites in Germany and Sweden with varying micropollutant exposure. High-quality assemblies were produced for each population (German, Swedish, and combined), followed by functional annotation to identify coding regions, signal peptides, transmembrane domains, and conserved protein domains. This dataset provides a valuable resource for studying the molecular responses of G. pulex to environmental stressors, supporting its use as a sentinel species in ecotoxicogenomics and ecological monitoring.
