UASt regulatory sequences drive expression of an inverted repeat.
Expression of Rcd-1rGD17713 under the control of either Scer\GAL4Act5C.PU or Scer\GAL4tub.PU results in an approximately 70% reduction in male fertility. Female fertility is unaffected.
Expression of Rcd-1rGD17713 in the germline under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 produces male fertility defects, producing approximately 60% of the offspring in controls.
Expression of Rcd-1rGD17713 in the accessory gland under the control of Scer\GAL4Acp26Aa.PC has no effect on male fertility.
Testes from flies expressing Rcd-1rGD17713 under the control of Scer\GAL4Act5C.PU show specific defects in structure, including disorganised cysts, tumor formation and/or misoriented sperm bundles. Motile sperm are produced but they either fail to fertilize wild-type female eggs, or the fertilised eggs fail to develop.
Adults expressing Rcd-1rGD17713 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.
Rcd-1rGD17713, Scer\GAL4VP16.nanos.UTR has male semi-fertile phenotype, non-suppressible by Rcd-1UAS.cCa, Scer\GAL4VP16.nanos.UTR
Expression of Rcd-1Scer\UAS.cCa fails to suppress the male fertility defects seen when Rcd-1rGD17713 is expressed under the control of Scer\GAL4nos.UTR.T:Hsim\VP16.
