wrm-1 mutants were grown at the permissive temperature (15C), and then shifted to the restrictive temperature (25C) soon after the division of Z1/Z4. After the temperature shift, cki-1::GFP was expressed weakly in both daughters.
Over-expression of the end-1 gene from heat shock promoters (nearly) completely suppressed the "no intestine" phenotype induced by wrm-1 RNAi in embryos
