Expression of cv-2Scer\UAS.cBa under the control of Scer\GAL4en-e16E causes a reduction in wing size and loss of the posterior crossvein.
Scer\GAL4en-e16E, cv-2UAS.cBa has wing vein L4 phenotype
Co-expression of ltlScer\UAS.cSa and cv-2Scer\UAS.cBa under the control of Scer\GAL4en-e16E results in additive effects on wing size reduction and synergistic effects on wing patterning, including deletions of vein L4 in the proximity of the presumptive posterior crossvein.
