Usly described [10]. Data analysis was performed using qbasePLUS (Biogazelle) and reference gene stability was tested using geNorm [81]. The three most stable reference genes chosen for the current analysis in all species and all tissues were dynein light chain 1 cytoplasmic, U6 snRNA-associated Sm-like protein lsm8, and mRNA turnover protein 4 homolog with collective M (and CV) values for Atlanti
