Intergenerational effects of early life-stage temperature modulation on gene expression and DNA methylation in Atlantic cod (Gadus morhua)
After suffering several collapses, the cod farming industry is now in the process of trying to re-establish itself. We have used material from Norway’s National Cod Breeding Program to study how different early life-stage temperature regimes affect DNA methylation and gene expression. Long-term effe...
