Developmental stage of animals was scored 72 and 48 hr after eggs were laid at 20° and 25°, respectively. All developmental distributions are shown in cumulative form. Is alleles indicate integrated transgenes. Transgenes shown in brackets. Transgenes were driven by the apl-1 promoter unless otherwise noted; the encoded protein is indicated; DAF-16::GFP is driven by the daf-16 promoter. ynIs106 carries a transgene that contains the apl-1(yn32) missense mutation in the region encoding the extracellular domain; this transgene does not rescue apl-1(yn10) null lethality and is considered a nonfunctional APL-1EXT control. N = number of animals observed. T = number of independent times experiment was performed. L4440 RNAi, empty vector control. Note that Gems et al. (1998) reported that daf-2(e1370); daf-12(m20) animals at 25.5° were found as L1 (43%) and L2 or L3 (57%), but no dauers or adults were observed. SUR-5::GFP was used as a co-injection marker for ynIs71 and ynIs86, Pmyo-2::GFP for ynIs106, and rol-6(su1006) for ynIs79 and ynIs100. For statistical analysis: P-values were determined by one-way ANOVAs with Tukey post-test (95% confidence intervals) for survival rate and χ2 (4 d.f.) for developmental progression and are only indicated when P < 0.001. For P-values against controls at the indicated temperature, see footnotes a–f and i. STE, standard error.
