UASt regulatory sequences drive expression of an inverted repeat.
Expression of bnlGD3070 in larval tracheal cell under the control of Scer\GAL4Nach.PL blocks migration and results in diminished or absent pupal abdominal tracheae.
Mosaic expression of bnlGD3070 in small patches along the tracheal migration path using Scer\GAL4prd.PU and Scer\GAL4Act5C.PI arrests migration, so long as the patch encompasses the full dorsal trunk circumference.
Adults expressing bnlGD3070 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.
bnlGD3070 is rescued by bnlUAS.cSa/Scer\GAL4Hand.Δ
