Fig. 6. Effect of feeding sterols at different concentrations on dauer arrest at 25°C. Sterols were at 12.9 µM (1x), the standard concentration for cholesterol in NGM, unless indicated otherwise. (A) hsd-1(mg433); ncr-1(nr2022) with increasing sterol concentrations. (B) hsd-1(mg433); ncr-1(nr2022) with decreasing sterol concentrations. (C) ncr-2(nr2023); ncr-1(nr2022). Total numbers scored are above the corresponding columns with the error bars representing the s.d. based on at least three replicates. Number in parentheses indicate average population density (worms/plate) ±s.d.
