DNA repair in N2, glp-1, and xpa-1 starved L1 larvae. Repair was not detected in xpa-1 larvae, and not detectably different from wild-type N2 larvae in glp-1 larvae. Time and strain had a significant effect on lesion frequency (P = 0.007 and 0.003, main effects of time and strain, respectively), and the effect of time was different for different strains, indicating differential repair for some strains (P = 0.04, time × strain interaction). Among the different strains, xpa-1 was different from N2 and glp-1 (P = 0.002 in both cases) but N2 and glp-1 were not different from each other (P = 0.87). n = 2 to 3 per point; error bars represent standard errors of the mean.
