Detailed Description
Statement
Reference

Heterozygous adults show transformation of antenna to leg.

Partial transformation of antennae into legs. Flies exhibit diminished chemosensory jump behaviour to ethyl acetate but no change in the jump response to a visual stimulus.

Homeotic transformation of antennae to mesothoracic legs.

Enhanced by ph-d2.

Antennae to leg transformation.

Transformation of antenna to prothoracic leg identity.

Antenna are leg-like.

Antenna partially leglike but less extreme than AntpYu and may overlap wild type. Enhanced by Pc. Enhanced by Pc2. Enhanced by ssa. AntpB ssa/+ ssa has virtually complete antennal leg including coxa, tibia, femur, and tarsus but no sex comb in the male (B. Holloway, cited in FBrf0020044). RK3A.

Reference

The frequency of antenna-to-leg transformation seen in AntpB heterozygotes is increased by expression of Glut4EFd.Scer\UAS under the control of Scer\GAL4Glut4EF-NP7418.

Homeotic transformation of antennae to T2 leg seen in AntpB flies can be redirected by pbhs.PB from ectopic leg to maxillary palp.

Comments
Comments

The wing positioning defects in In(3R)AntpB flies were previously attributed to an effect on Antp (FBrf0107412 and FBrf0155711), however, FBrf0204343 demonstrates that these phenotypes are instead due to an effect on Glut4EF, which is also disrupted by the In(3R)AntpB chromosome.

FlyBase curator comment: FBrf0155711 attributes the wing positioning defects in In(3R)AntpB flies to an effect on Antp. However, FBrf0204343 demonstrates that the Glut4EF gene is also disrupted by the In(3R)AntpB chromosome, and that the wing positioning defects seen are instead due to an effect on Glut4EF.
