Video 2. Calcium imaging of ISCs expressing trpA1 RNAi in response to paraquat.
Midguts expressing GCaMP6s reporter together with trpA1 RNAi in ISCs were dissected and imaged in AHL buffer. Z-stack images were acquired with 10 s interval. A maximal intensity z-projection was shown in the movie. A final concentration of 4 mM oxidant agent paraquat was added at 150 s (the 15th frame of the movie).
