"To further confirm this genetic pathway for dauer regulation by epistasis analysis, we constructed
csu60;
daf-12(
tu389) double mutants and found that they resembled the Daf-d phenotype of
daf-12(
tu389) (Ogawa et al. 2009) (Supplementary Table S1), consistent with the expected position of
csu60 acting upstream of the nuclear hormone receptor."
