| Summary: | Many organisms can generate alternative phenotypes from the same genome, enabling individuals to exploit diverse and variable environments. A prevailing hypothesis is that such adaptation has been favoured by gene duplication events, which generate redundant genomic material that may evolve divergent functions. Vertebrate examples of recent whole genome duplications are sparse, although one example is the salmonids, which have undergone a whole genome duplication event within the last 100 million years. The life-cycle of the Atlantic salmon, Salmo salar, depends on the ability to produce alternating phenotypes from the same genome, to facilitate migration and maintain its anadromous life history. Here we investigate the hypothesis that genome-wide and local gene duplication events have contributed to the salmonid adaptation. We used high throughput sequencing to characterise the transcriptomes of three key organs involved in regulating migration in S. salar: brain, pituitary and olfactory epithelium.
