Different genetically sensitized backgrounds did not reveal a function for agr-1.

Agr-1 mutants were tested in different genetic backgrounds and the following phenotypes were analyzed: a, locomotion; b, response to touch on head and tail; c, sensitivity to levamisole; d, sensitivity to aldicarb; e, muscle integrity by DIC; f, muscle integrity by rhodamine-phalloidin staining; g, muscle integrity (myosin fibers) in worms expressing MYO-3::GFP (stEx30); h growth rate; i, paralysis progression; m, brood size, n, thrashing assay; p, egg laying; q, gonad displacement; r, gonad arm migration; s, pharynx pumping-rate in feeding worms. *, tested at 15°C and at 20°C.
