(A,B) Poly(A) tail length in individually sequenced clones after 3′RACE analysis of ND1 transcripts in dmpnpaseKD, dmpnpaseKD/dmsuv3KD, dmsuv3OE, dmpnpaseOE, dmpnpaseOE/dmsuv3OE, and control (w;;) larvae at 4 days AEL. (C) Quantification of mitochondrial mRNA steady-state levels of dmpnpaseOE (dmmtpapKO/FM7;;UAS-dmpnpase/daGAL4 or FM7;;UAS-dmpnpase/daGAL4 or FM7/Y;;UAS-dmpnpase/daGAL4), dmmtpapKO (dmmtpapKO/Y;;) dmpnpaseOE/dmmtpapKO (dmmtpapKO/ Y;;UAS-dmpnpase/daGAL4), and control (w;;) larvae at 4 days AEL. Histone was used as loading control. (D) Mitochondrial mRNA steady-state levels in dmlrpprc1KD, dmlrpprc1KD/dmsuv3KD, dmlrpprc1KD/dmpnpaseKD, and control (w;;) larvae at 4 days AEL, as determined by qRT-PCR. RP49 was used as an endogenous control. (E) 3′RACE analysis of poly(A) tails of ND1 transcripts in dmlrpprc1KD (w;;UAS-bsfRNAi#1/daGAL4), dmlrpprc1KD/dmsuv3KD (w;UAS-dmsuv3RNAi/+;UAS-bsfRNAi#1/daGAL4), dmlrpprc1KD/ dmpnpaseKD (w;UAS-dmpnpaseRNAi/+;UAS-bsfRNAi#1/daGAL4), and control (w;;) larvae at 4 days AEL. All data are represented as mean +/- SEM (***p < 0.001, **p< 0.01, *p< 0.05, n = 5).
