Diaphanous Is Required for the Formation of the Mitotic Actin Cortex
(A–C) Apical and intermediate views (xy) of Lifeact::GFP in control (A), Dia RNAi (B), and Arp3 RNAi epithelia (C). Yellow asterisks mark mitotic cells. Scale bars, 5 μm.
(D) Comparison of cortical/cytoplasmic filamentous actin at several time points before anaphase for control, Arp3, and Dia RNAi conditions. (Mean ± SD, n ≥ 30 cells from at least 3 different pupae.)
