Transcriptome of the tick Ixodes uriae. Ticks were collected on three different sites in the arctic region (Grimsey, Gull Island, Hornoya) and in colonies of three different species of sea-birds (common guillemot, kittiwake, puffin). Ticks samples included nymphs (unfed or fed), adult females (unfed or fed) and adult males, for which RNAs were extracted separately. Twelve libraries (characterized by a combination Site x Host x Condition) were obtained, by pooling between 5 and 30 individuals. Five RNA-Seq de novo assemblies were obtained with Trinity (corresponding to five different Site x Host combinations. Then a meta-assembly was obtained with the runMeta program (DRAP software, SIGENAE). This meta-assembly was annotated with Trinotate.
