Flies expressing AxnEDDNmut.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4arm.PS exhibit a "denticle lawn" phenotype, followed by embryonic lethality. Generation of wing disc clones expressing AxnEDDNmut.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4vg.int2.1 results in the production of rudimentary wing stumps.
