RNA-Seq of hypo- and hyper-salinity stress-response transcriptome in the brain of greater amberjack (Seriola dumerili) juveniles

Salinity is an important abiotic stress, has significant effect on the physiological and metabolism activities, reproduction, growth, survival and development of marine fish. The greater amberjack (Seriola dumerili) is a large, fast-growing species with high commercial value in aquaculture worldwide. We performed RNA-seq analysis of the brain to identify the genes and molecular biological processes involved in response to salinity changes. The candidate genes identified in this study provide a basis for further research on the molecular mechanisms of salinity adaptation and transcriptional plasticity of marine fish.
