UASt regulatory sequences drive expression of an inverted repeat.
Expression via Scer\GAL4da.G32 has no effect on development when flies are reared in normoxia or in 5% oxygen (hypoxic) conditions, compared to controls.
Adults expressing uifGD139 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.
Expression under the control of Scer\GAL4Mef2.PR results in a weak flyer phenotype.
Expression under the control of Scer\GAL4pnr-MD237 may result in lethality or semi-lethality at the pupal stage, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in extra bristles on the notum in 0% or 30-40% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 10-20% or 50-60% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
Expression under the control of Scer\GAL4pnr-MD237 results in the absence of 0% or 90-100% of the Scer\GAL4pnr-MD237-expressing area of the notum, depending on the insertion line used.
Expression of uifGD139 under the control of Scer\GAL4btl.PS results in 5% embryonic lethality and 87% larval lethality. The mutant larvae show a growth defect.
Larvae expressing uifGD139 under the control of Scer\GAL4btl.PS spend very little time in the food and instead wander around the plate, even if they appear to have mostly inflated trachea (a behaviour that has been shown to be a response to hypoxia).
Expression of uifGD139 under the control of Scer\GAL4da.G32 results in 18% embryonic lethality and 86% larval lethality.
Expression of uifGD139 under the control of either Scer\GAL4btl.PS or Scer\GAL4da.G32 results in a nearly completely penetrant tracheal defect in newly hatched larvae. The expressivity of the phenotype is variable.
Expression of uifGD139 under the control of Scer\GAL4en-e16E results in almost no embryonic lethality and animals have completely inflated tracheae.
