Lifespan curves of N2 wildtype animals grown on agar plates with E. coli as a food source in comparison to those measured in liquid axenic medium is shown in (a). Lifespans of CL2070 in axenic liquid medium either in the absence (control) or presence of 100 or 250 μM juglone are given in (b). P-values for significances of differences of survival curves were P = 0.7907 for 100 μM juglone and P < 0.0001 for 250 μM juglone versus the untreated CL2070 nematodes
