microchaeta & wing
prothoracic leg & sex comb
wing vein L3 & macrochaeta
60% of flies carrying pbhs.PB that are also heterozygous for taraL4 show partial truncation of the distal part of wing vein L4. This phenotype is not seen in either pbhs.PB single mutant or taraL4/+ single mutant flies. Deletions of wing vein L5 are also seen in the double mutant flies.
The addition of Scr4 suppresses and the addition of skdpap-53 enhances the ectopic distal sex comb phenotype. The addition of Scr4 to pbhs.PB, skdpap-53 flies also suppresses the distal sex comb phenotype.
pbhs.PB HE31/Ras85De1F triple heterozygotes have deletions of the distal portions of wing veins L4 and L5, up to and including the posterior crossvein. The spacing and position of the campaniform sensilla along the proximo-distal axis of wing vein L3 is altered.
Shows a dose-sensitive interaction with Df(2L)net-PMF, Df(2L)30A-C, Df(2L)TW50, Df(2R)en30, Df(2R)PC4, Df(3L)GN24, Df(3L)AC1, Df(3R)by10, Df(3R)by416, Df(3R)GB104, Df(3R)P115 and Df(3R)L127. Does not interact with Df(3R)by62. Df(3R)by10, Df(3R)by416 and Df(3R)GB104 reduce the antennal to maxillary transformation caused by pbhs.PB. pbhs.PB Ras85De1B double heterozygotes have a partially penetrant truncation of wing veins L4 and L5, and the frequency of ectopic bristle formation on the distal end of wing vein L3 (seen in pbhs.PB heterozygotes) is increased to 90% for females and 50% for males. pbhs.PB Df(3L)AC1 double heterozygotes show a very weak modification of the pbhs.PB wing phenotype. Gap1sxt-BJ61 enhances the antenna to maxillary transformation in pbhs.PB/+ Gap1sxt-BJ61/Gap1sxt-BJ61 flies. This enhancement is reduced if the flies also carry one copy of Ras85De1B. Enhances the ectopic wing vein phenotype seen in Gap1sxt-BJ61 homozygotes. This enhancement is reduced if the flies also carry one copy of Ras85De1B.
