Influence of HGQ on the survival rate of paraquat-stressed N2 nematodes. Synchronized nematodes were treated with or without HGQ at indicated concentrations at 20°C for 24 h prior to exposure to 60mM paraquat, and the live/dead nematodes (~100 for each treatment) were scored every 12 h until all dead. The representative Kaplan-Meier survival curves are shown from three independent experiments, and data are compared for significance by the log-rank test.
