Overexpression of sqaScer\UAS under the control of Scer\GAL4ptc-559.1 results in the disappearance of anterior crossveins in adult wings.
The anterior crossvein appears normal in wings co-expressing both sqaScer\UAS and sqadsRNA.Scer\UAS under the control of Scer\GAL4ptc-559.1.
The sqaScer\UAS-induced anterior crossvein defects can be suppressed by co-expressing sqhT20A.S21A.Scer\UAS under the control of Scer\GAL4ptc-559.1.
