An Hsp70 promoter drives expression of the complete rl coding sequence, tagged at the N-terminal end with a nuclear localisation signal (Tag:NLS(SV40-largeT)) and tagged at the C-terminal end with Tag:HSV-1-gD.
Ectopic expression of rlhs.T:SV40\nls2,T:Hsim\gD for 1 hour at various times during development has no effect on the pattern of veins in the adult wing. Similarly, when rlhs.T:SV40\nls2,T:Hsim\gD flies are raised continuously at 29oC, no effects are seen in wing vein patterning. Ectopic expression of rlhs.T:SV40\nls2,T:Hsim\gD produces blisters in 1-5% of adult wings when rlhs.T:SV40\nls2,T:Hsim\gD is transiently expressed between late L3 and mid pupation (96-168 hours after egg deposition), in addition to an increase in the number of cells within the wing.
