Expression of Hsap\SRFScer\UAS.T:Hsim\VP16 under the control of Scer\GAL4prd.RG1 in embryos induces myosin accumulation without changing epidermal cell shape.
Expression of Hsap\SRFScer\UAS.T:Hsim\VP16 under the control of Scer\GAL4c381 has no effect on amnioserosal cell shape.
When expressed under the influence of Scer\GAL4tracheal, extra cytoplasmic processes, which go on to form lumens, and terminal branches form. Outgrowth occurs earlier than usual and in an unregulated fashion. The extra cytoplasmic processes do not grow towards their usual targets, but in random directions.
