Table 3. Rescue of homozygous nobo^KO embryos by maternal sterol administration. The numbers of the first instar larvae that were offspring of nobo^KO/CyO Act-GFP mothers, which were fed standard cornmeal food with yeast pastes containing 0.5%(w/w) each sterol, are indicated. Genotype was assessed by the presence of a GFP signal and genomic PCR results (See Supplementary fig. S2).
