Detailed Description
Statement
Reference

Animals lacking endogenous N (Df(1)N-54l9/Y) and rescued by one copy of N+t40 do not exhibit a loss of wing veins.

Flies that carry a single copy of N+t40 in a wild-type genetic background display extra veins in the wing. This phenotype is dosage sensitive as animals carrying two copies of N+t40 show an enhancement of the extra and expanded wing vein phenotypes with occasional blisters in the wing.

Additional Comments
Genetic Interactions
Statement
Reference

The wing blistering phenotype seen in the posterior compartment of wings in flies expressing EogtGD5084 under the control of Scer\GAL4en.PU in the presence of Dcr-2Scer\UAS.cDa is dominantly partially suppressed if the flies also carry N+t40.

Comments

The wings of flies that carry a single copy of N+t40 in a N55e11/+ genetic background appear normal compared to wild-type. The lethality of N55e11 in hemizygous males can be rescued with by a single copy of N+t40. The rescued flies resemble wild-type animals.
