Expression of a single copy of zip^{HMM.Scer\UAS.T:Avic\GFP} under the control of Scer\GAL4^en-e16E results in wing that generally appear wild type, with a mild expansion of the posterior crossvein in 33% of wings. Expression of two copies of zip^{HMM.Scer\UAS.T:Avic\GFP} under the control of Scer\GAL4^en-e16E results in a more severe phenotype; 30% of wings have blisters.

Expression of a single copy of zip^{HMM.Scer\UAS.T:Avic\GFP} under the control of Scer\GAL4^en-e16E in a zip¹/+ background results in a wing vein expansion phenotype in 41% of wings.
