Fig. 3. Interference with genes that process mitochondrial proteins selectively activates mitochondrial chaperone genes. The top row of panels shows photomicrographs of wild-type (N2) animals exposed to the indicated RNAi; the panels below are photomicrographs of GFP fluorescence of hsp-6::gfp, hsp-60::gfp, hsp-4::gfp, hsp-70::gfp, cts-1::gfp and aco-2::gfp animals exposed to mock RNAi or RNAi of the indicated genes.
