"In two models of mitochondrial stress, feeding of
spg-7(RNAi) as well as a previously characterized temperature-sensitive allele (
zc32) (Benedetti et al., 2006), GFP fluorescence increased over the course of postembryonic development. The increase in fluorescence and GFP levels was attenuated in
haf-1(
ok705) deletion animals (Figures 1A and 1B)."
