Figure 3  dbl-1 genetically interacts with mua-3 mutants. (A) RNAi of TGFβ2 homolog (dbl-1) rescued the mua-3 lethality at 25°. The numbers are average percent survival ± SEM. (B) A mutation in dbl-1 did not rescue the mua-3 lethality at 25°. (C) A mutation in dbl-1 reduces the survival of mua-3 at 15°.
