Abstract Background The diversity of metazoan cell shapes is influenced by the dynamic cytoskeletal network. With the advent of RNA-interference RNAi technology it is now possible to screen systematically for genes controlling specific cell-biological processes including those required to generate distinct morphologies. Results We adapted existing RNAi technology in Drosophila cell culture for use in high-throughput screens to enable a comprehensive genetic dissection of cell morphogenesis. To identify genes responsible for the characteristic shape of two morphologically distinct cell lines we performed RNAi screens in each line with a set of double-stranded RNAs dsRNAs targeting 994 predicted cell shape regulators. Using automated fluorescence microscopy to visualize actin filaments microtubules and DNA we detected .
