Movie 5

Myotubes at 36 h APF are under mechanical tension Single plane spinning disc confocal movie of two myotubes labelled by Mef2-GAL4, UAS-GFP-Gma at 36 h; the lower one is partially severed by a UV laser at the right side (see Supplementary Figure 2). Note the recoil of the wound indicating tension. Time is indicated in seconds and starts at the cut. Movie plays with 5 frames per second.

Mechanical tension and spontaneous muscle twitching precede the formation of cross-striated muscle in vivo
