Expression of TspScer\UAS.AD.cSa in the embryonic glia that cover all peripheral nerves (under the control of Scer\GAL4repo) does not lead to any somatic muscle pattern defect.
Scer\GAL4repo, TspUAS.AD.cSa, slowUAS.Tag:HA has larval somatic muscle cell phenotype
Scer\GAL4repo, TspUAS.AD.cSa, slowUAS.Tag:HA has muscle attachment site phenotype
Ectopic expression of TspScer\UAS.AD.cSa and slowScer\UAS.T:Ivir\HA1 together, under the control of Scer\GAL4repo results in a clear change in the directionality of somatic muscles; in addition, the morphology of the muscle ends is affected, and the edge of the muscles appears pointed. In some cases, the pointed muscle end is directed towards an ectopic site of Tsp and slow accumulation, whereas other muscles are associated with the correct attachment site at the segmental border, but their morphology is abnormally pointed.
Ectopic expression of TspScer\UAS.AD.cSa and slowScer\UAS.T:Ivir\HA1 together in muscle 12 during its migration, under the control of Scer\GAL45053A results in a morphological alteration of the muscle ends. Overexpression of TspScer\UAS.AD.cSa or slowScer\UAS.T:Ivir\HA1 alone does not affect muscle morphology.
Third-instar larvae overexpressing both TspScer\UAS.AD.cSa and slowScer\UAS.T:Ivir\HA1 driven by Scer\GAL4Mef2.PR exhibit torn muscles.
