<b><i>de novo</i></b><b> transcriptome assembly and annotation of </b><b><i>Gammarus pulex</i></b><b>: a valuable resource for ecotoxicogenomics</b>

This study presents the <i>de novo</i> transcriptome assembly and annotation of <i>Gammarus pulex</i>, a freshwater amphipod crucial to ecotoxicology due to its ecological significance and sensitivity to pollutants. Three distinct transcriptomes were generated from <i>G. pulex</i> collected at sites with varying levels of micropollutant exposure across Germany and Sweden. High-quality transcriptomes were assembled for each population (German, Swedish, and combined) using RNA sequencing (RNA-Seq). Functional annotation identified coding regions, signal peptides, transmembrane domains, and conserved protein domains within the transcripts. This comprehensive transcriptomic resource enhances our understanding of <i>G. pulex's</i> molecular responses to environmental stressors, particularly micropollutant stress. The identified genes and pathways provide potential biomarkers for ecological monitoring and facilitate future ecotoxicogenomic studies, further reinforcing <i>G. pulex</i> as a sentinel species for aquatic ecosystem health.Please refer to the "Readme.txt inside the directory to get an overview of the file structure and contents.<br>
