Figure 7From: A fitness assay for comparing RNAi effects across multiple C. elegans genotypesLoss of RNAi effects if the initial concentration of food is too low. Bristol or Hawaii worms were RNAi-treated with empty vector (ev), lin-31, pos-1 or mel-26, as indicated. Both pos-1(RNAi) and mel-26(RNAi) effects were lost if about half the initial concentration of food was used.Back to article page
