The female-virgin flies (w; Δ2,3) and male flies (yw) were collected for microinjection. The collected flies were kept in the 25℃ incubator separately.
In total 50 pairs were collected.

2. NaCl/Triton X-100, 10% Na-hypochloride, H2O were kept on ice.
3. The tape was placed on the cover glass (3M tape, Cot No. W-18 pastes on the center).
4. parafin oil is prepared.
5. 1mg/ml DNA in microinjection buffere is prepared.
6. glass needles for microinjection were prepared.
7. The early embryos were collected on the nylon mesh and washed 3-4 times with NaCl/Triton X-100. Then　 　　　embryos were dechorinated with 5 % Na-hypochloride. Then the dechorionated embryos were washed 7-8 times 　with H2O.
