    Statement
    Reference
    Homozygotes develop more slowly, are smaller and less active that heterozygous siblings. Chie5.5/Chig1 transheterozygotes die as larvae.
    Heterozygotes have normal wings. Embryos derived from germ-line clones fail to hatch, cuticles exhibit normal dorsal-ventral polarity but severe segmentation defects. Phenotype is less severe at 25oC than 18oC. Wild type paternal Chi does not substantially alter development.
    Chie5.5 homozygotes show pathfinding errors in the neurons that normally express ap; the neurons are highly defasciculated, choosing inappropriate pathways within the connectives. The projections of tup-expressing intersegmental nerve motor neurons show no clear alterations compared to wild type in homozygous embryos.
    Clones in the wing disc induced in the second larval instar stage can cause a bifurcation and outgrowth of the dorsal wing pouch. Clones are comparable in size to their twin spots in both the dorsal and ventral compartments. Dorsal clones in the wing induced in the second larval instar stage induce ectopic wing margin structures along their borders and induce outgrowth of the dorsal compartment of the wing. Ventral clones produce no phenotype. Dorsal clones in the wing induced in early third larval instar stage (72 hours after egg laying) at or near the endogenous margin induce ectopic wing margin tissue. Clones at a distance from the wing margin induce blistering, without inducing ectopic wing margin. Mutant cells in clones in the dorsal compartment at the anterior wing margin differentiate ventral margin identity. Clones in the wing induced in mid third larval instar stage (96 hours after egg laying) do not induce ectopic margin.
    Heterozygotes are morphologically normal.
    Flies carry somatic clones homozygous for Chie5.5 in their legs have defects in all segments including fusion of tarsal segments 4 & 5 and loss of the unguis (claw).

    Chie5.5/ap56f transheterozygotes display wing margin defects: gaps in the posterior margin.
    Enhances wing scalloping of Bx3/+.
    Heterozygotes show a cut wing phenotype in combination with mutants in the 'Nipped' genes. Has no effect on the eye phenotype of Nspl-1.
    No increase in axon guidance defects is seen in apmd544/Chie5.5 transheterozygotes compared to apmd544/+ or Chie5.5/+ embryos. ap::ChiΔLID.ΔLIM.Scer\UAS.T:Hsap\MYC rescues the axon defects seen in Chie5.5 embryos when expressed under the control of Scer\GAL4ap-md544. The axon defects seen in Chie5.5 apmd544/apP44 double mutants are completely rescued by ap::ChiΔLID.ΔLIM.Scer\UAS.T:Hsap\MYC expressed under the control of Scer\GAL4ap-md544.
    Chie5.5 clones in the wing disc of animals expressing SerScer\UAS.cSa under the control of Scer\GAL4Bx-MS1096 cause axis bifurcation. Chie5.5 clones in the dorsal compartment of BxhdpR590 wing discs are much larger than their twin spots, whereas those in the ventral compartment are comparable in size to their twin spots.
    Double heterozygotes for Chie5.5 and SsdpKG03600, SsdpBG01663, Ssdpneo48, Ssdp31 or Ssdp11 have scalloped wings.
    Chie5.5/+; apUGO35/+ and Chie5.5/+; apmd544/+ flies have no visible leg phenotypes.

    In Chie5.5 a gypsy insertion that blocks the wing margin enhancer reduces ct expression more than deletion of the wing margin enhancer.
