Breakpoint in Ubx.
Ubx130 heterozygotes display slightly enlarged halteres compared to wild-type.
In Ubx130 mutant adults, halters are homogeneous in size and shape, being slightly larger than those in wild-type.
Ubx130 heterozygotes have normal halteres and nota.
Like Ubx1 as a dominant. RK1A.
Increases the frequency of the trx bithorax-variegated phenotype in heterozygous combination with Df(3R)red-P52.
Flies carrying both RpII215Ubl and Ubx130 show a greater transformation of haltere to wing than flies carrying RpII215Ubl alone.
T(2;3)T1-19/Ubx130 flies show reduced viability and fecundity.
The frequency of variegated bithorax transformations seen in Df(3R)red-P52 heterozygotes is increased in flies also containing a copy of Ubx130.
Heterozygotes have a slight transformation of haltere to wing at 29oC and 17oC. Ubx130/UbxCbx-1 flies show a temperature sensitive phenotype; flies grown at 29oC have a slight conversion of haltere to wing and strong transformation of wing to haltere, while those grown at 17oC have a strong haltere to wing transformation and a slight transformation of wing to haltere. The UbxCbx-1 transformation in the wing is generally reduced and the Ubx130 transformation in the haltere is generally enhanced in the transheterozygote, compared to heterozygous or homozygous UbxCbx-1 or Ubx130 flies respectively.
Ubx130 has haltere phenotype, enhanceable by Df(3L)Aprt-21
Trl13C, Ubx130 has haltere phenotype, enhanceable by Df(3L)Aprt-21
Ubx130/Ubxbx-3 has haltere disc anterior compartment phenotype, suppressible | partially by Scer\GAL4ptc-559.1/tkvUAS.cLa
Ubx130/Ubx[+] is a suppressor | partially of capitellum phenotype of dppd5/dppd12
2.48% of flies carrying one copy of TrlR85 and one copy of Ubx130 show a mild haltere to wing transformation.
Homozygous bip2Fa4a does not enhance the frequency of haltere to wing transformation seen in TrlR85/TM2, Ubx130 flies (2.73% of flies show transformations, compared to 2.48%), but it does enhance the severity of the transformation.
Double heterozygous lolalk02512 Ubx130 flies do not show significant increase in the expressivity of the Ubx phenotype. lolalk02512/+; Trl13C/Ubx130 flies display a higher frequency (18%) of strong haltere-to-wing transformations compared to Trl13C/Ubx130 siblings (6.3%). This increased transformation is often accompanied by a notal transformation.
56% of Ubx130, Trl13C double heterozygotes have halteres that quite heterogeneous in size and larger than Ubx130 alone. 63% of Ubx130, Df(3L)Aprt-21 double heterozygotes have halteres that quite heterogeneous in size and larger than Ubx130 alone. 78% of Ubx130, Df(3L)Aprt-21, Trl13C triple heterozygotes have halteres that quite heterogeneous in size and larger than Ubx130 alone, also exhibiting a stronger phenotype than any two of the alleles used. The haltere becomes a wing -like structure with wing veins and hairs on the wing margin.
Ubx130/TrlR85 flies have a low penetrance of haltere to wing transformations and notal transformations. The penetrance of these phenotypes is significantly enhanced by heterozygosity for Df(2R)Δ18, even though the phenotypes are present at a very low penetrance (<0.5%) in Ubx130, Df(2R)Δ18 double heterozygotes.
Heterozygotes have slightly enlarged halteres compared to wild type. Trl13C+/+Ubx130 double heterozygous flies have larger halteres than Ubx130 heterozygotes. Homeotic transformations include a low frequency of patches on the haltere and postnotum that develop like wing and notum tissues respectively.
Temperature-shift experiments show that the temperature sensitive period in Ubx130/UbxCbx-1 flies extends throughout embryonic and larval life.
The brm2 or trxE2 mutations greatly increase the frequency of haltere to wing transformation in double heterozygotes with Ubx130.
