Fig 3. Ptbb-6::GFP reporter expression defines a UPRmt independent pathway.
(A) Ptbb-6::GFP is less strongly induced by mutation of ETC subunits than by RNAi knockdown, whereas Pgst-4::GFP expression displays an opposite pattern. (B) Treatment of ctb-1(qm189) mutants with RNAi targeting complexes I, III, IV or V [nuo-2, isp-1, cco-1 and one-tenth strength atp-3, respectively], underscores the reciprocal relationship between Ptbb-6::GFP and Pgst-4::GFP reporter expression. Quantification data for both (A) and (B) is provided in S6 Fig.
