UASt regulatory sequences drive expression of an inverted repeat.
Scer\GAL4pnr-MD237-mediated expression of spdoKK103906 causes a large number of sensory organ precursor cells adopting a pIIb fate, resulting in a partially naked notum.
Scer\GAL4pnr-MD237, Usp12-46GD12106, spdoKK103906 has tormogen cell phenotype
Scer\GAL4pnr-MD237, Usp12-46GD12106, spdoKK103906 has mesonotum phenotype
When both spdoKK103906 and Usp12-46GD12106 are expressed using Scer\GAL4pnr-MD237, an intermediate phenotype is observed characterized by the production of double-bristles or even double-sockets.
