UASt regulatory sequences drive expression of an inverted repeat.
Expression of watGD343 under the control of Scer\GAL4btl.PS leads to a complete lack of tracheal liquid clearance during embryonic development. The embryos hatch but die during the first instar larval stage. Expression under the control of Scer\GAL4salm.TE or Scer\GAL4kni.TE results in normal gas filling and viable flies.
Adults expressing watGD343 under the control of the cardioblast-specific Scer\GAL4tin.CΔ4 driver show significantly reduced survival on day 6 after a shift to 29[o]C compared to control flies.
Adults expressing watGD343 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.
