We developed selective conditions for long-lived mutants of the nematodeCaenorhabditis elegansby subjecting the first larval stage (L1) to thermal stress at 30° for 7 days. The surviving larvae developed to fertile adults after the temperature was shifted to 15°. A total of one million F2progeny and a half million F3progeny of ethyl-methanesulfonate-mutagenized animals were treated in three separate experiments. Among the 81 putative mutants that recovered and matured to the reproductive adult, 63 retested as thermotolerant and 49 (80%) exhibited a >15% increase in mean life span. All the known classes of dauer formation (Daf) mutant that affect longevity were found, including six new alleles ofdaf-2, and a unique temperature-sensitive, dauer-constitutive allele ofage-1. Alleles ofdyf-2andunc-13were isolated, and mutants ofunc-18, a gene that interacts withunc-13, were also found to be long lived. Thirteen additional mutations define at least four new genes.
