Additional file 1: of Dynamics of nuclear receptor gene expression during Pacific oyster development

Gene expression of selected reference genes in Crassostrea gigas among different life stages. Three housekeeping genes selected as reference genes (centred Ct values): elongation factor-1ι: white bars; ribosomal protein S18: light grey bars; ribosomal protein L7: dark grey bars; mean of all reference genes including significantly different groups: black bars and letters. hpf: hour post fertilisation. dpf: days post fertilisation. E: unfertilised eggs. F: female. M: male. (DOC 43 kb)
