    Detailed Description

    Reference

    Class I dendritic arborizing neurons in sw1/+ larvae raised at 25[o]C become bipolar, as compared to multipolar in wild type, but do not display a change in the number of dendritic branches.

    A low percentage of sw1 flies exhibit partial deletion of wing margins, particularly at the posterior, and defective wing venation.

    Dendritic arborization neurons show an altered distribution of Golgi outposts in sw1229/sw1 larvae compared to controls. Golgi outposts can be seen moving from the soma into the axon and travelling anterogradely and retrogradely within the axon.

    About 60% of the actin nuclear bundles and individualization complexes are disrupted in the testis of sw1 hemizygous males. The F-actin density in the investment cones is not significantly different from wild-type spermatids.

    swDic-2/sw1 flies have a mild wing phenotype at 28oC. Mutant flies have a variable wing phenotype, including defects in wing venation and incised margins, reduced fertility and rough eyes.

    Above 23oC, most sw1 flies have spread and incised wings with irregular veins; eyes reduced and roughened. Male expression more extreme than female. RK2 at 28oC.

    +/Df(1)mal10 and +/sw1 exhibit short-wing phenotype in presence of RpII215Ubl.

    15% of males eclose at 25oC; show wing and eye abnormalities; above 31oC, sw1 is lethal. At 17oC, most flies are wild type; at 14oC, all are wild type.

    Statement
    Reference

    The supernumerary dendrite phenotype seen in animals expressing dar1Scer\UAS.cYa under the control of Scer\GAL4eve.RN2 (in unipolar motor neurons) or Scer\GAL4P2.4.Pdf (in adult unipolar PDF neurons) is greatly reduced in sw1/+ mutants.

    The wing margin and wing vein defects of sw1 dop1 double mutants are more severe than either single mutant, sometimes resulting in 'crippled' wings.

    The defect in membrane growth in dop1 embryos is strongly enhanced by sw1.

    ctpexc39; sw1/Y mutants are viable at 25oC. The double mutants show a slight enhancement of the disruption of individualization complexes seen in both single mutants.

    Almost all ctpins1; sw1/Y and ctpDIIA82; sw1/Y males fail to emerge, at either 25oC or 18oC.
