A transcriptome resource for the Arctic Cod (Boreogadus saida)

Abstract

Arctic Cod ( Boreogadus saida ) serve as an important link in Arctic food webs and are thus considered an important species for environmental monitoring. RNA-Seq was conducted on samples from wild-collected individuals representing various age classes and tissue types to obtain as complete a transcriptome as possible on an Illumina MiSeq, which resulted in a total of 64,457 transcripts with an average length of 295 bp. We identified well-known genes that are associated with temperature change or response to pollutants. This RNA-Seq effort provides the first insight into the B. saida transcriptome, which can be a starting point for investigations identifying genes for local adaptation and genomic responses to future environmental change.
