Table 4. Subset of overrepresented Gene Ontology (GO) terms linked to the biological processes mitosis/cell cycle and heart development.
Overrepresented GO terms were identified through enrichment analysis, conducted in Blast2GO, of the 808 genes differentially transcribed by juvenile Atlantic salmon reared in unenriched and enriched hatchery environments. The total number of genes (i.e. microarray features) associated with each of the GO terms is indicated. Significance of the Fisher’s exact test (FDR < 5%) of GO term overrepresentation is also shown.
