  • Numbers in parentheses indicate the sample sizes. 

  • * The sample is significantly different from its respective siblings on OP50; P values = 0.05 according to the 2-tailed Student's t test. 

  • The sample is significantly different from the N2 sample on the same food source; P values = 0.01. ND, not done. The worms often flee from the GD1 food and migrate off the plate, perhaps in search of a more nutritious food source. Both types of Q-replete E. coli strains contain similar amounts of quinone; OP50 contains 117.9 ± 2.7 pmol of Q8 per mg wet wt, whereas GD1:pAHG produces 138.2 ± 3.4 pmol of Q8 per mg wet wt.
