Detailed Description

Reference

Nnd-1 mutant flies exhibit significantly enhanced 24 hour long-term memory formation.

Nnd-1 hemizygous males have notched wings and thickened wing veins.

Nnd-1 mutant flies display a notched-wing phenotype.

At 18[o]C the eyes of Nnd-1 mutant adults are only slightly smaller and rougher than wild-type, moderate notching of the wing margin is also observed.

Male flies hemizygous for Nnd-1 show wings with minor margin nicking.

Mutants show gaps in the wing margin and reduced wing blade size.

Nl1N-ts1/Nnd-1 adults are produced at the permissive temperature.

Nnd-1 causes limited nicking in the margin of the adult wing.

Nnd-1/Y animals have extra joint material in the tarsal segment 4 but not in segment 3.

Nnd-1 mutants have notched wings.

Nnd-1 is a temperature-sensitive allele. In homozygous Nnd-1 mutants at 29[o]C, eyes are rough and reduced in size. They also exhibit extreme wing notching and thickened wing veins.

Nnd-1 mutants show significantly reduced mean character size for orbital bristles compared to Canton-S flies.

Wings show a cut phenotype, similar to that of ct53d.

Wing margin is scalloped. Wing veins are slightly thickened. Phenotype suggests loss of function effect in one context (wing margin formation) and gain of function effect in another (wing vein formation).

Homozygotes exhibit a weak N loss of function phenotype, having notched wings. This phenotype is fully penetrant but slightly variable.

Mutant flies show a weak loss of function phenotype and produce a slight excess of neural cells. Mutant cells in clones can influence their neighbours since fewer than expected wild type bristles are found along the mosaic borders.

Thickened wing veins with deltas and variably notched wing margins.

Thick wing veins, wing nicks along the apical, anterior and posterior margins.

Notching of the wing tip at 25oC.

The haplo-insufficient phenotype in the mesonotum is an increase in microchaetae density when Nnd-1 and Nnd-3 are in combination with N amorph alleles.

Wing notches in the adult. SerD/Nnd-1 transheterozygotes display a synergistic phenotype: loss of anterior and posterior wing margins and loss if distal wing blade tissue. Nnd-1/Df(3R)Bd males exhibit a significantly increased mutant wing phenotype compared to Nnd-1 alone.

Homozygous wing margins are excised. Wing phenotype can be enhanced in severity by vg and sca mutations. Phenotype can be suppressed by extra copies of sca+ and vg+.

Nnd-1/dxENU and Nnd-2/dxENU transheterozygous flies never reach adulthood, stage not determined. Enhance wing phenotype.

N/Nnd-1 heterozygotes are partially viable and relatively infertile.

Homozygotes have slightly small, rough eyes, extreme apical and marginal notches in the wing and thick wing veins at 29oC. At 25oC, the eyes are weakly rough, notches are seen in the wing and the wing veins are thick. At 18oC, the eyes are normal and the wings have weak nicks.

Similar to and phenotypically non-complementary with Nnd-3. Semilethal when heterozygous with dominant visible alleles of N : survivors are relatively infertile.

The wing nicking phenotype caused by expression of domdsRNA.Sym.Scer\UAS under the control of Scer\GAL4bbg-C96 is enhanced if the flies are also carrying Nnd-1/Y.

The wing nicking phenotype caused by expression of Rbf280.Scer\UAS under the control of Scer\GAL4bbg-C96 is enhanced if the flies are also carrying Nnd-1.

Heterozygosity for ebi2g1 enhances the notched wing margin and thickened wing vein phenotypes seen in Nnd-1 hemizygous males.

Nnd-1, Past160-4 double homozygous flies reach adulthood at a very low frequency, and die after 1 day. The wings are more severely notched compared to Nnd-1 mutant flies.

Nnd-1, Past1110-1 double homozygous flies reach adulthood at a very low frequency, and die after 1 day. The wings are more severely notched compared to Nnd-1 mutant flies.

The slightly reduced eye size and moderate wing margin nicking observed in the temperature-sensitive Nnd-1 homozygous adults at 18[o]C is enhanced by wgGla-1 heterozygosity: the ventral half of the adult eye is virtually completely lost and the wing notching phenotype is exacerbated too.

Wings from male flies hemizygous for Nnd-1 and heterozygous for RpL13AEP3614.A show a severe loss of wing material compared to Nnd-1/Y wings, whereas wings from RpL13AEP3614.A heterozygotes appear wild type.

Heterozygosity for Nipped-A323, Nipped-ANC96, Nipped-ANC106, Nipped-ANC186, Nipped-ANC194 or domk08108 further reduces the width of Nnd-1 wings.

Co-expression of Rtf1dsRNA.Sym.Scer\UAS under the control of Scer\GAL4hs.PB at 27[o]C significantly decreases the width of Nnd-1 wings relative to controls.

dom7 enhances the wing nicking phenotype of Nnd-1.

Nnd-1/Y, Su(dx)sp have extra, reversed polarity joints in tarsal segments three and four.

Wing notching in Nnd-1 mutants is enhanced by heterozygosity for Su(Tpl)s1, Su(Tpl)17, Su(Tpl)XS-706, Su(Tpl)10, or Su(Tpl)S-192.

The wing notching phenotype seen in hemizygous Nnd-1 animals is enhanced by the addition of ebiE4.

Wing vein thickening is enhanced by Su(dx)Scer\UAS.cCa driven by Scer\GAL4Bx-MS1096. Wing margin loss and wing size reduction are also evident.

Nnd-1/Y flies exhibit a minor wing nicking phenotype, and strongly enhance the wing nicking phenotype seen in mamN.Scer\UAS, Scer\GAL4C96 flies.

l(2)41Ae7, ap56f and Su(H)8 have little or no effect on the Nnd-1 cut wing phenotype.

Nnd-1/Y; vgs2/vgs2 flies show notching of the wing. Nnd-1/Y; hi22/+ flies have severe notching of the wings.

Notched wing phenotype dominantly enhanced by Su(H)16.

Synergistic interaction of phenotype with that of sno71e3 mutation.

The Nnd-1 wing phenotype is enhanced by one copy of RpL19P, Df(2R)ES1 or Df(2R)M60E. The wing notching phenotype is also enhanced by RpL19ex1, RpL19ex16, RpL19ex51 RpS5a2 and Df(3R)M86D, M(2)2011 and RpS174.

A 'N[nd-1]' stock obtained from Spyros Artavanis-Tsakonas (termed 'SAT N[nd-1]') was found to contain a mixture of two different chromosomes: (i) the Nnd-1-dse mutation alone (at relatively low frequency); and (ii) the Nnd-1-dse mutation together with the 41 bp deletion within the N coding region described by Harding-Theobald et al. 2007 (FBrf0195930). A 'N[nd-1]' stock obtained from the Drosophila Stock Center (termed 'DSC N[nd-1]') contains only the chromosome containing both lesions. The Nnd-1-dse lesion appears to have been the original mutation, with 'N[nd-1]' flies originally containing this mutation alone. However, the chromosome containing both the Nnd-1-dse lesion and the 41 bp deletion within the N coding region has almost completely displaced the original chromosome in the 'SAT N[nd-1]' stock and has completely displaced it in the 'DSC N[nd-1]' stock.

FlyBase curator comment: The 'N[nd-1]' stock has been found to have acquired a second mutation in N over time (see FBrf0209477 for details). The Nnd-1-dse lesion (mutation in the Downstream Sequence Element of the consensus polyadenylation site) appears to have been the original mutation, with a 41 bp deletion within the N coding region occurring later. Data in FlyBase curated from individual papers using 'N[nd-1]' have been retained under the N[nd-1] allele record (FBal0012890), which represents the double mutant chromosome, unless it is clear that the chromosome being studied contains only the original lesion, in which case the data has been moved to the Nnd-1-dse allele record (FBal0282136). It is thus possible that some of the papers and curated data listed under N[nd-1] in FlyBase (especially information from older papers) describe experiments carried out using the Nnd-1-dse chromosome, but there is insufficient information to be sure.
