Expression of a single copy of zip^Rod.Scer\UAS under the control of Scer\GAL4^en-e16E results in most wings having blisters. These are mostly confined to the posterior compartment, although sometimes a blister may extend into regions of the anterior compartment adjacent to the compartment boundary. Cells in the posterior wing show a multiple wing hair and branched hair phenotype. Expression of two copies of zip^Rod.Scer\UAS under the control of Scer\GAL4^en-e16E results in a more severe phenotype; 74% of wings show loss of posterior compartment tissue.

Expression of a single copy of zip^Rod.Scer\UAS under the control of Scer\GAL4^en-e16E in a zip¹/+ background results in loss of posterior compartment tissue in 100% of wings.
