Expression stability of candidate reference genes in the different tissues. Stability of the reference genes was evaluated in Gills (A), Digestive Gland (B), Gonads (C), Mantle (D), Foot (E) of M. galloprovincialis based on geNorm (red circle), NormFinder (blue square) and Bestkeeper (green triangle) analyses of the RT-qPCR experiments. Data is arranged in descending order of comprehensive stability from left to right
