Detailed Description
	Statement Reference ds[UAO71]/ds[38k] flies have abnormally shaped wings, but wing area is not much altered compared to controls. The flies have a planar polarity phenotype in the wing. Flies expressing ds[Act5C.T:Avic\GFP-EGFP] in a ds[UAO71]/ds[38k] background show a reduction in wing area compared to wild type. Flies expressing ds[SAx3.Act5C.T:Avic\GFP-EGFP] in a ds[UAO71]/ds[38k] background show a reduction in wing area compared to wild type. (Brittle et al., 2010) ds[38k]/ds[UAO71] wings show a planar cell polarity phenotype; reverse orientation and swirling of wing hairs is seen in the proximal region of the wing with high penetrance. ds[38k]/ds[UAO71] animals show defects in the directional preferences of growing microtubules in mutant wing cells compared to wild type; growing microtubules fail to converge along the proximodistal axis as strongly as in wild type. The distally biased asymmetry of microtubule growth that is seen in the wild-type is substantially weakened in the mutant at the anterior crossvein and at the L3-1 location (position of the most proximal dorsal campaniform sensillum on vein L3) at 24 hours after puparium formation (APF). In addition, plus end-proximal microtubules are more abundant at the L3-3 location (position of the most distal dorsal campaniform sensillum on vein L3) in the mutants at 24 hours APF (microtubule polarity is symmetrical at this position in wild-type flies at this stage). (Harumoto et al., 2010) In approximately 5% of ds^38k homozygous escapers the wing is replaced by a winglet and, posterior to it, a lateral protuberance that looks like an scutum and scutellum. The winglet is composed of proximal anterior structures arranged in a mirror-image duplication. The smallest examples of these winglets consist of a mirror image duplication of anterior hinge structures - the tegula and humeral sclerite. Larger examples also have a rudimentary wing blade consisting of a mirror image duplication of anterior structures - the costa and anterior wing margin. This phenotype is also seen occasionally in ds^38k/ds^33k flies (3 out of 72 heminota), ds^38k/ds⁰⁵¹⁴² (approximately 2% of heminota) and ds^38k/ds^UAO71. In late third instar discs of ds^38k homozygotes with a reduced wing pouch, marker expression indicates that the pouch is entirely within the anterior compartment. This absence of posterior cells in the wing territory can be seen as early as the mid second instar. ds^38k/ds¹ flies have legs with reduced segment size and fusion of the tarsal segments and partial elimination of the tarsal joints. (Rodriguez, 2004) ds^38k/ds^UAO71 flies have disorganised ommatidial polarity; no obvious equator is present. Flies expressing ds^{Scer\UAS.P\T.cSa} under the control of Scer\GAL4^αTub84B.PL in a ds^38k/ds^UAO71 background have a normal overall pattern of polarisation in the eye; an equator can easily be discerned. 97.6% of ommatidia are correctly constructed and rotated in these animals. Expression of ds^{Scer\UAS.P\T.cSa} under the control of Scer\GAL4^fj-VG1 in a ds^38k/ds^UAO71 background results in eyes with disorganised ommatidial polarity. (Simon, 2004) When homozygous somatic clones are made in the eye, approximately 29% of ommatidia display dorsal ventral inversions, while fewer than 1% of genetically mutant ommatidia display anterior posterior inversions. Inverted equators also occur in 83% of clones. These arise along the equatorial border of the clone rather than within the clone. Also ectopic equators are seen, albeit rarely. In homozygous mutant eyes (generated by mitotic recombination using the "EGUF/hid method"), 31% of ommatidia display dorsal ventral inversions. The endogenous equator is stil evident. When ommatidia are examined that are mosaic (with respect to ds^38k) in the pair of photoreceptor cells, R3 and R4, 77% of the time the mutant cell is R3 and the wild-type cell R4. When the pair R2 and R5 are examined, 65% of the time the mutant cell is R2 and the wild-type cell R5. When the pair R1 and R6 are examined, 73% of the time the mutant cell is R1 and the wild-type cell R6. (Rawls et al., 2002) The dorsal-ventral polarity of ommatidia in ds^38k/ds^UAO71 flies is partially randomised. Defects in anterior-posterior ommatidial polarity or rotation are not seen. Somatic clones of ds^38k in the eye: about 45% of ommatidia inverted on their dorsoventral axes. The clones also show directional nonautonomy, with most ommatidia on the equatorial boundary being inverted (78% in total), but few ommatidia being inverted on the polar boundary (10% total). (Strutt and Strutt, 2002) The eyes of ds^UAO71/ds^38k escapers have eyes with ommatidia that randomly adopt either dorsal or ventral polarity. (Yang et al., 2002) ds^38k clones in a M(2)24F¹ background are large like the controls, but cell density is increased. In ds^38k,ft^k07918 clones only epistatic effects of ft^k07918 are seen. (Garoia et al., 2000) 40% eclosion rate. In addition to 100% penetrant defects in leg, wing and thorax, rough patches in the eye appear at low frequency. Anterior crossvein is displaced posteriorly. Legs are stubby with a reduced number of tarsal joints. There are duplicated bristles on the notum and the wings are held out stiffly with duplicated crossveins. Flies have difficulty walking, cannot jump or fly, do not reproduce and die within a few days of eclosion. (Clark et al., 1995) ds^38k/ds¹ flies have an extreme ds phenotype. (Curry, 1939) ds^38k/ds¹ has close crossveins; fly short and thick bodied. Homozygote probably like ds^d. RK2.

Additional Comments
Genetic Interactions
Statement Reference ds[38k]/+ enhances the ommatidial rotation defects induced by the overexpression of dgo[Scer\UAS.cFa] under the control of Scer\GAL4[hs.2sev]. (Weber et al., 2012) Adding fj[p1]/fj[d1] has little effect on the wing area of ds[UAO71]/ds[38k] flies. Adding fj[p1]/fj[d1] dramatically reduces the wing area of flies expressing ds[Act5C.T:Avic\GFP-EGFP] in a ds[UAO71]/ds[38k] background. Adding fj[p1]/fj[d1] has no effect on the wing area of flies expressing ds[SAx3.Act5C.T:Avic\GFP-EGFP] in a ds[UAO71]/ds[38k] background. Adding fj[p1]/fj[d1] has no effect on the wing area of flies expressing ds[SDx3.Act5C.T:Avic\GFP-EGFP] in a ds[UAO71]/ds[38k] background. (Brittle et al., 2010) wg^{l-12.Scer\UAS}; Scer\GAL4^dpp.blk1 suppresses duplication of the wing pouch and prospective notum in ds^38k homozygous wing discs, although the hinge domain is expanded compared with the wild type. Normal anterior-posterior subdivision is also restored in these discs. These animals die before reaching adulthood. dpp^Scer\UAS.cCa; Scer\GAL4^bi-omb-Gal4 does not suppress duplication of the wing pouch and prospective notum in ds^38k homozygous wing discs. However, the resulting discs have an expanded, rather than a reduced wing pouch, and anterior-posterior subdivision of the wing pouch is restored. nkd²/+ partially suppresses the leg phenotype of ds^38k/ds¹ flies: tarsal joint formation is completely rescued and the size of the tarsal segments is recovered almost to that of wild type. (Rodriguez, 2004) ds^38k fj^N7/ds^UAO71 fj^d1 flies have disorganised ommatidial polarity; no obvious equator is present. Flies expressing both fj^Scer\UAS.cZa and ds^{Scer\UAS.P\T.cSa} under the control of Scer\GAL4^αTub84B.PL in a ds^38k fj^N7/ds^UAO71 fj^d1 background have a disorganised ommatidial polarity; no obvious equator is present. Flies expressing ds^{Scer\UAS.P\T.cSa} under the control of Scer\GAL4^αTub84B.PL in a ds^38k fj^N7/ds^UAO71 fj^d1 background have a disorganised ommatidial polarity; no obvious equator is present. Flies expressing fj^Scer\UAS.cZa under the control of Scer\GAL4^αTub84B.PL in a ds^38k fj^N7/ds^UAO71 fj^d1 background have a disorganised ommatidial polarity; no obvious equator is present. Flies expressing ds^{Scer\UAS.P\T.cSa} under the control of Scer\GAL4^fj-VG1 in a ds^UAO71 fj^VG1/ds^38k fj^N7 background have a disorganised ommatidial polarity; the eye contains a clearly perceptible equator in which most of the nearby ommatidia are reversed in polarity and thus point away from the equator. Flies expressing both fj^Scer\UAS.cZa and ds^{Scer\UAS.P\T.cSa} under the control of Scer\GAL4^αTub84B.PL in a ds^38k fj^N7/ds^UAO71 fj^d1 background have normal polarity throughout the wing blade with the exception of a small region along the anterior proximal margin of the wing, where a small swirl is often present. Flies expressing ds^{Scer\UAS.P\T.cSa} under the control of Scer\GAL4^αTub84B.PL in a ds^38k fj^N7/ds^UAO71 fj^d1 background have normal polarity throughout the wing blade with the exception of a small region along the anterior proximal margin of the wing, where a small swirl is often present. (Simon, 2004) The wing shortening phenotype of fj^d1 homozygotes is enhanced by ds^38k/+. Reduction in the distance between anterior and posterior cross-veins in fj^{t14.T:Hsap\GALNT3} flies is enhanced by ds^38k/+. Like ds^38k/ds^UAO71 flies, ds^38k/ds^UAO71; fj^{109-583.Scer\UAS.T:Hsap\GALNT3} ; Scer\GAL4^bi-omb-Gal4 flies have inverted ommatidia scattered throughout their eyes. (Strutt et al., 2004) Wing discs from l(2)gd1¹, ds^38k double mutants are large and have variable morphology, often with a series of frill-like folds on the edges of the discs. Leg discs are larger and thicker than for l(2)gd1¹ alone. The haltere disc duplicates, triplicates or quadruplicates. The eye antenna disc shows a pair of knob-like structures in the anterior of the antenna field that probably represent presumptive antennae. Animals usually die in the larval or early pupal stage, and never reach the pharate adult stage. Clones double mutant for l(2)gd1¹ and ds^38k form protrusions due to abnormal morphogenesis that might result from an excess of cells. Imaginal discs from ds^38k l(2)gd1¹/l(2)gd1¹ larvae resemble those of ft⁸ l(2)gd1¹/l(2)gd1¹ rather than l(2)gd1¹/l(2)gd1¹ in that wing, haltere, second and third leg discs are duplicated.
