Expression of salrIKEA.IKVA.Scer\UAS.T:Avic\GFP-EYFP under the control of Scer\GAL4salm.EPv results in ectopic wing vein material in the L2-L3 intervein region and a general reduction in wing size (the phenotype is stronger than that caused by expression of salrScer\UAS.T:Avic\GFP-EYFP under the control of Scer\GAL4salm.EPv).
