English: Peristalsis in a Midgut Junction region missing the Midgut Junction DH31 expressing cells. The movie shows the peristalsis within the anterior midgut junction region over the course of 50 seconds (total run time ~1.5 minute). The movie has been looped three times, and the rate increased to 4 frames per second from 2. The anterior midgut junction region is noted by the remains of the muscular tethers which come into view when the midgut rotates during play. In this example, the Midgut Junction DH31 expressing cells were ablated by expression of UASricin via the DJ752 Gal4 driver. Although there are no contractions during this period, the midgut does rotate due to gut motility further down the intestine.
