Expression of org-1Scer\UAS.cSa under the control of Scer\GAL4twi.2PE leads to thickening of alary and thoracic alary-related muscles and formation of one extra muscle with alary muscle-like morphology in embryos.
Expression of org-1Scer\UAS.cSa under the simultaneous control of both Scer\GAL4how-24B and Scer\GAL4twi.2PE causes severe disruption of the somatic muscle pattern in 100% of segments. The number of twi-positive lateral adult muscle precursor cells is increased compared to wild type.
