Identification of genes associated with heat tolerance in Arctic charr exposed to acute thermal stress

Abstract: Arctic charr is an especially attractive aquaculture species given that it features the desirable tissue traits of other salmonids and is bred and grown at inland freshwater tank farms year round. It is of interest to develop upper temperature tolerant (UTT) strains of Arctic charr to increase the robustness of the species in the face of climate change and to enable production in more southern regions. We used a genomics approach that takes advantage of the well-studied Atlantic salmon genome to identify genes… Show more

“…We recently identified genes putatively associated with tolerance and intolerance to acute thermal stress in Arctic charr (16). Specifically, we used a combination of quantitative trait locus (QTL) association and expression analysis to examine genes differentially expressed in fish that were more and less tolerant to acute exposure to upper lethal temperature (ϳ25°C).…”

“…These resources, which are collectively referred to as the GRASP (Genomic Research on All Salmon Project) arrays, have been used extensively for gene expression studies throughout the salmonid genomics world. For example, recent studies have used the GRASP arrays to look for genetic markers of immune responses in Atlantic salmon (LeBlanc et al, 2010), as well as of thermal stress in rainbow trout (Lewis et al, 2010) and Arctic charr (Quinn et al, 2011a(Quinn et al, , 2011b, and to predict spawning failure in wild sockeye populations (Miller et al, 2011).…”

“…The use of transcriptspecific oligonucleotide arrays may overcome some of these challenges. For these reasons, profiling using microarrays is sometimes described as an exploratory tool, for which the data must be interpreted with a caution, or which must be followed up or correlated with other types of analysis (Lewis et al, 2010;Quinn et al, 2011a).…”
