Loss of nhr-69 enhances the dauer phenotype of TGF-β signaling mutants.

Numbers represent percent dauer formation (average ± S.E.M.). N = population size. Three young adults of each genotype were placed on NG agar plates seeded with OP50, then removed after they laid 40–50 eggs. Dauer formation in the F1 generation was scored visually at:a20°C,b22.5°C, or,c25.5°C.Progeny reaching the L4 stage after 3–4 days (depending on the temperature) were counted and removed. Remaining progeny were scored as dauer larvae.*Compared to wild type.**Compared to single mutant.
