Description

Insertion of a Tirant element in the Ser 3'UTR (coordinates 3R:27172910..27172913 , release 6 genome).

Insertion of a 5.5kb Tirant element in the 3' untranslated region of the last exon 81bp downstream of the translational stop codon, resulting in truncation of the Ser RNA eliminating putative RNA degradation signals.

5.5-kb insert at 0 to 3.0 kb.

Detailed Description
Statement
Reference

Ser1/+ adults display a wing-notching phenotype.

Ser1/+ wings have a notched phenotype.

Heterozygotes exhibit a wing notching phenotype.

Heterozygotes show slight scalloping of the wing blade along the tip and towards the posterior margin.

Wing margin phenotype not affected by Su(dx)sp.

Heterozygotes exhibit loss of distal wing margin material, phenotype is enhanced in homozygotes. SerBd-3/SerD transheterozygotes exhibit loss of distal wing margin material, similar to SerD heterozygotes.

Heterozygotes show notching of the wing, in particular in between the second and fifth wing veins.

Homozygotes and heterozygotes exhibit scalloping of the wing margin due to cell death during pupal stages.

Wings of Ser1/+ and hemizygous Ser1 notched at tip; deepest notch at second posterior cell. In triploids, one dose of Ser1 overlaps wild type. As with other Ser alleles expression suppressed by H and N. Dominant wing phenotype; homozygous viable.

Hemizygotes and homozygotes are viable. Notches on wing tip between the third and fifth vein. Penetrance and expressivity of phenotype in heterzygotes is slightly affected by temperature: fully penetrant at 18oC and weaker at 28oC.

Heterozygotes have wing notches in the adult: dominant wing-nicking phenotype. SerD/Nnd-1 transheterozygotes display a synergistic phenotype: loss of anterior and posterior wing margins and loss of distal wing blade tissue. SerD/Dp(1;2)51bV76e flies have wild type wings.

Ser1 is homozygous viable; initially thought to be homozygous lethal, but lethality removable by recombination; the closely linked lethal persists in many Ser1-bearing chromosomes. Homozygous Ser1 produces extreme incision of wing margins especially in second posterior cell.

Reference

The wing-notching phenotype characteristic for Ser1/+ adult flies is partially suppressed by combination with a single copy of trrK662X.

The Ser1/+ wing phenotype is suppressed by Scer\GAL4Bx-MS1096-mediated overexpression of NdfipScer\UAS.T:Ivir\HA1.

The wing notching phenotype of Ser1 heterozygotes is dominantly suppressed by Utx1, Utx2 and Utxf01321.

The wing notching phenotype seen in SerD/+ animals is enhanced by the addition of ebiE4.

Addition of fz3unspecified to SerD flies enhances the wing notching phenotype seen in these flies. A second copy of fz3unspecified enhances this phenotype further and results in additional posterior margin notching.

sdSG29.1/+ ; SerD/+ flies show an enhancement of wing scalloping with a total loss of sensory bristles along the posterior margin and the loss of some bristles along the anterior margin. Hemizygous sdSG29.1 in combination with SerD/+ results in a deeply scalloped posterior margin. Sensory bristles are completely lost from the posterior margin and there are very few bristles along the anterior margin.

The scalloping of the wing margin seen in SerD/+ heterozygotes is enhanced if the flies also carry kuz1405Rev4/kuzk01405.

hrgP1/hrgP1; SerD/+ flies show synergistic enhancement of the notched wing phenotype, with deeper wing notching than is seen in either hrgP1/hrgP1 or SerD/+ single mutant flies, and loss of most of the first wing vein. The notching is also not restricted to sites between the second and fifth wing vein. The 'delta' phenotype and wing confluence phenotype of Df(3R)Dl-FX3 flies is suppressed by SerD.
