Movie 1

Embryogenesis of maternal mutant embryo of DE-CadS4A::GFP. The movie is recorded by time-laps from starting stage 7 at 5min interval. The total recording time is 9 hours, with GFP channel at left and DIC channel at right. The genotype the embryo (ovo-FLP w / +; FRT-G13 DE-CadS4A::GFP) was confirmed by the absence of twi-Gal4 UAS-GFP expression. DE-CadS4A::GFP is too weak to be seen in this recording. Note the failed germ-band retraction starting 06:30 in DIC channel. Time stamp in “hh:mm” format.
