      Reference
      Metathoracic outpushing is a uniform, narrow, hairy band. Balancers depressed, inflated, with elongated pointed tip and heavy line of costal bristles. Base of third leg shows sternopleural bristles like those of normal second leg. Metathoracic development of Ubxbx-34e/Ubxbx-34e > Ubxbx-34e/Ubxbx-W > Ubxbx-34e/Ubxbx-1. Ubxbx-34e/Ubx1 has round, flat, wing-like halteres; Ubxbx-34e Ubx1/+ + = Ubx1/+ (Lewis). Complements Ubxbxd-1. Reasonable viability and fecundity. Highly constant expression and easy separability. Expression increased slightly at 29oC, decreased at 15oC. RK2.
      Homozygotes show homeotic transformation of anterior haltere to anterior wing.
      The frequency of variegated bithorax transformations seen in Df(3R)red-P52 heterozygotes is not increased in flies also heterozygous for Ubxbx-34e.
      Moderate transformation of anterior third thoracic segment to second thoracic segment.
      Ubxbx-34e shows the "ppx" transformation at 17oC: ventral regions of T2p and T3p are affected.
      Flies usually have normal transversal fascicles in the adult CNS, although the anterior dorsal T3 fascicle is sometimes slightly malformed.
      Haltere are transformed to wing and are 10-15% of wing size, dorsal tissue of T3 is incompletely transformed to metanotum, hypopleural plates are incompletely transformed to sternopleural plates, 8-9 hypopleural bristles are still present and the anterior third leg displays a strong transformation to anterior second leg, as seen by the bristle pattern. Phenotype can be suppressed by su(Hw) mutations.
      Different genetic combinations of Pc alleles and Ubx alleles suggest that the products of the bx region of Ubx are responsible for the "cbx" phenotype of the Pc mutations and in the absence of Pc the overexpression of bx gene products suppresses the pbx insufficiency phenotype in the posterior segments.
      Homozygotes and transheterozygotes of Ubx alleles demonstrate a significant enhancement of the bx phenotype when in combination with E(bx)2. Haltere to winglike and metanotum to mesonotumlike transformations are enhanced.
      Ubx1/Ubxbx-34e flies have very little transformed dorsal metanotum.
      Does not affect the frequency of the trx bithorax-variegated phenotype in heterozygous combination with Df(3R)red-P52.
      Ubxbx-34e/Ubx1 flies do not have a T3a to T2a notal transformation. In the presence of a transvection suppressing chromosome rearrangement (TSR) the notum is strongly transformed.
      The Ubxbx-34e phenotype is not suppressed in flies carrying su(Hw)wt or su(Hw)Δ656-705 in a su(Hw)7/su(Hw)V background, partly suppressed in flies carrying su(Hw)Δ706-736 or su(Hw)Δ881-944 in a su(Hw)7/su(Hw)V background, and strongly or completely suppressed in flies carrying su(Hw)Δ673-943, su(Hw)Δ2-203.673-943, su(Hw)Δ738-780, su(Hw)Δ2-203, su(Hw)Δ853-880 or su(Hw)Δ782-944 in a su(Hw)7/su(Hw)V background.
      Ubx6.28/Ubxbx-34e mutant combinations cause a homeotic transformation of the third thoracic segment to the anterior second thoracic segment. The haltere (T3) is also transformed toward wing fate (t2), manifested by increases in size and the development of bristles.
      Homozygotes have an enlarged haltere, with long, dark costal bristles. Heterozygotes have wild-type halteres.
      Ubx61d, Ubxpbx-1/Ubxbx-34e mutants show a haltere-to-wing transformation.
      Ubxbx-34e flies show a haltere to wing transformation.

      zae(bx) enhances the development of the dorsal metanotum in Ubxbx-34e/Ubx1 from a few hairs to a broad band of hairy tissue somewhat like that seen in Ubxbx-34e homozygotes.
      Double heterozygotes for ash128 at 27oC exhibit haltere to wing transformation and third to second leg transformation. No transformation phenotype is seen at 20oC. Double heterozygotes for ash218 at 27oC exhibit haltere to wing transformation.
      The halteres of z1-35/Y Ubx1/Ubxbx-34e or z1-42/Y Ubx1/Ubxbx-34e males are larger than those of their z+ counterparts, and males have dorsal mesothoracic tissue on their metathorax. This effect is stronger for z1-35 than for z1-42.
      The frequency of transformation of halteres into wings seen in Dsp11/Y flies is enhanced by Ubxbx-34e/+. The enhancement is dramatically reduced if the female parents are heterozygous rather than homozygous for Dsp11.
      The addition of E(bx)Nurf301-2, E(bx)ry122 or Df(3L)3643 to Ubxbx-34e/Ubx6.28 animals enhances the anterior transformation seen in both the third thoracic segment and the haltere.
      Ubxbx-34e Abd-BMc double heterozygous females show a significant increase in the level of monoene cuticular hydrocarbons and a significant decrease in the level of 7,11-diene cuticular hydrocarbons compared to wild-type females.
      Ubxbx-34e/+ flies carrying Dp(1;Y)y+mal106 have a punctate line of short, dark bristles on the capitellum and a denser cluster of bristles at the distal tip. Ubxbx-34e/+ flies expressing DIP1c.Scer\UAS under the control of Scer\GAL4Bx-MS1096 have long bristles along the entire surface of the haltere.
      Df(2R)ED3921 fails to suppress the haltere to wing transformation of Ubxbx-34e flies.

      The sensitivity of the metanotal transformation of the Ubxunspecified/Ubxbx-34e genotype to chromosomal rearrangements has been studied in the presence and absence of za.
      Partial revertant has been obtained that provides evidence that the gypsy element is responsible for the mutant phenotype.
      Ubx mutants have been classified into "transvection groups", on the basis of transvection tests with Ubxbx-34e, Ubxpbx-2, and UbxCbx-1 Ubx1 mutants.
      Source of the gypsy element.
      The phenotype of a number of combinations of Ubx mutations has been investigated to determine the role of the bxd regulatory region in the modulation of Ubx expression.
