Flies expressing Mul1miRNA.Scer\UAS.cYa under the control of Scer\GAL4Mef2.PU have slightly elongated mitochondria in the indirect flight muscles compared to wild type.
Expression of Mul1miRNA.Scer\UAS.cYa under the control of Scer\GAL4RapGAP1-OK6 results in a reduction in mitochondrial number and an increase in mitochondrial size in the larval salivary glands compared to wild type.
