    Compared with wild-type, the larval fat body of homozygous Ets97D613 mutants show reduced mitochondrial abundance. The morphology of mitochondria appear normal in Ets97D613 mutants.

    Mitochondrial DNA content (normalised to nuclear DNA) in Ets97D613 mutants is increased compared to that of controls.

    Ets97D613 mutants pupate with a one- or two-day delay compared with wild-type.

    Ets97D613/Df(3R)ro80b mutant fat body cells from third instar larvae contain a similar number of mitochondria to controls, but these mitochondria are strongly reduced in size. Despite the small size the morphology is unaffected. Levels of oxygen consumption, cytochrome c oxidase activity and cytochrome c protein levels are unaffected and the mitochondria have an increased mitochondrial membrane potential. The drop in oxygen consumption seen in controls in response to low-yeast food is still observed in Ets97D613/Df(3R)ro80b mutants. In contrast to wild type, in which the mitochondrial area drops in response to low yeast food, no difference is seen between normal-fed Ets97D613/Df(3R)ro80b mutants larvae and those on low-yeast food. No changes in mitochondrial abundance or morphology are seen in the gut, salivary gland, trachea or imaginal discs.

    Ets97D613/Df(3R)ro80b and Ets97D613/Ets97D902 flies die as pharate adults. Ets97Dtne-1 is viable but female sterile in transheterozygous combination with Ets97D613. Ets97Dtne-1/Ets97D613 females show abnormalities in oogenesis, including problems with nurse cell chromosome decondensation, follicle cell migration and chorion formation. Eggs obtained from these females show no obvious development.

    srlKG08646, Ets97D613 double mutants show a more severe mitochondrial phenotype in the fat body. The abundance of mitochondria in the fat body is further reduced compared with Ets97D613 single mutants. In contrast to the phenotype in the single mutants, the mitochondria in double mutants are rounded in shape and the inner-mitochondrial cristae are either missing or strongly reduced in size.

    Mitochondrial DNA content (normalised to nuclear DNA) in srlKG08646, Ets97D613 double mutants is further increased compared to that of Ets97D613 single mutants.

    The delay in pupation is increased to four days in srlKG08646, Ets97D613 double mutants.

    Ets97D613/Df(3R)ro80b does not significantly affect the increase in cell size seen in fat body clones expressing InRScer\UAS.cHa under the control of Scer\GAL4αTub84B.PP.

    Ets97D613/Df(3R)ro80b partially suppresses increase in cell size seen in fat body clones expressing MycScer\UAS.cSAa under the control of Scer\GAL4αTub84B.PP.

    Ets97D613/Df(3R)ro80b suppresses the increase in cell size seen in fat body clones co-expressing CycDScer\UAS.cDa and Cdk4Scer\UAS.cMa under the control of Scer\GAL4αTub84B.PP.

    The reduced mitochondrial abundance seen in Cdk43 or Ets97D613/Df(3R)ro80b mutants alone is not enhanced in the double mutants.
