Differential Gene Expression in Liver, Gill and Olfactory Tissues of Coho Salmon (Oncorhynchus kisutch) after Acclimation to Salinity.

ABSTRACT: Most Pacific salmonids undergo smoltification and transition from freshwater to saltwater. Saltwater acclimation requires salmonids to make various adjustments in color, shape, size, metabolism, catabolism, and osmotic and ion regulation. The molecular mechanisms underlying this transition are largely unknown. The present study acclimated coho salmon (Oncorhynchus kisutch) to four different salinities (<0.5, 8, 16, and 32 ppth) and assessed gene expression through microarray analysis of gill, liver and olfactory tissues. Gills are involved in osmotic regulation, liver plays a role in energetics, and olfactory tissues are involved in behavior. Between all salinity treatments, liver had the highest number of differentially expressed genes at 1,616. Gills had 1,074 differentially expressed ge
