Polytene chromosomes normal.
Deletion of intron 2.
Deletion of a major part of intron 2.
Deletion of DNA.
Deletes intronic regulatory element within intron 2.
Deletion of vg sequences. 5' end of the deletion maps at least 500bp from the 3' end of the upstream exon and the 3' end maps quite close to the 5' end of the downstream exon.
3kb deletion from + 5 to + 8; '+' values to right (distal); 0 coordinate assigned to insert position of vg21; Williams, Atkin and Bell (1990)
Co-expression of E2fScer\UAS.cNa, DpScer\UAS.cDa and BacA\p35Scer\UAS.cHa under the control of Scer\GAL4vg.int2.1 rescues wing appendage growth in vg83b27 flies; wing blade features such as bristles, wing veins and margin are often seen in the rescued appendages.
Partial, but significant rescue of the vg83b27 lack of wing phenotype is seen when Hsap\TDUScer\UAS.cVa is expressed under the control of Scer\GAL4vg.int2.1. The rescued wings have veins and wing margins.
