Project description:We report here the release of a multi organ transcriptome developped for the Arctic char Salvelinus alpinus. This reference set was obtained using the 454 GS FLX+ technology. A pool of one-year-old, immature offspring of wild, anadromous Arctic charr originating from Lake Varflusjoen, Svalbard (79oN), including both lean and fat individuals, and three-years-old mature offspring of charr originating from Lake Vårflusjøen, North-Norway (70oN) was sampled. In order to maximize the diversity of expressed transcripts, we sampled a variety of organs and tissues; the whole brain, gill and head kidney and pieces of the liver, gonad, abdominal fat and muscle.

Project description:Environmental hypoxia typically induces phenotypic remodelling in animals, including bolstered oxygen transport and storage, and glycolytic enzyme activities, typically coordinated by the transcription factor hypoxia-inducible factor (HIF). The calanoid copepod Daphnia responds to hypoxia by a HIF-dependent increase in expression of extracellular hemoglobin (Hb), however little is known about the glycolytic response. We compared the Daphnia from 4 lakes in terms of transcriptome using RNASeq analysis of red versus pale animals. Cluster analysis showed that the impact of lake was much greater than the impact of colour. However, in each lake there were a series of colour dependent differences, including many of the known targets of HIF in mammals.
