The three identified wing specific enhancers ap-RXa, Dad-Int52 and Dad-4 are inserted into the attP site in apattPΔEnh.
wing blade (with apDG3)
wing margin (with apDG3)
Most of the apRXaDad52.4/+ flies display normal wings. However, approximately 2 % of them show the loss of distal wing tissue.
apRXaDad52.4/apDG3 flies have tube-like wing stumps which lack wing margin completely except for the occasional occurrence of a few margin hairs at the very tip.
