Dorsal view of a pupa that carries hand-GFP and org-1-RFP and in which RNAi against italic>yki was induced ( org-1>>UAS-dsRNA-yki). The video starts at late stage P3 and shows that knockdown of yki prevents dedifferentiation of the AMs into mononucleate myoblasts, suggesting that Yki function is crucially required for the induction of this essential process during AM transdifferentiation. Frame rate is 4 frames per second.
