Overexpression of sup-18 in body-wall muscles enhances the defects of sup-10(n983gf) but not unc-93(e1500gf) mutants.

Locomotion rate, mean for 12 animals. Brood size, mean for 10 animals. Four extrachromosomal arrays (nEx) were generated, two containing lin-15(+) alone and two containing both lin-15(+) and sup-18(+), and were introduced into the different genetic backgrounds by mating to ensure consistent gene dosage among experiments. ND, not determined. LR: locomotory rate (bodybends/min).
