Expression of apHA-B.Scer\UAS when driven by Scer\GAL4ap-md544, causes abnormalities in the wing in a small percentage of flies. For example, wing blistering and pointed shaped wing can be observed. apmd544/apts78j flies grown at 25oC have wings that lack most of the wing margin but have good proximo-distal growth. The addition of apHA-B.Scer\UAS severely reduces proximo-distal growth and wing size.
