Adult wings containing homozygous Klp64Dk1 mutant clones show severe wing margin notches. Although mutant clones are found away from the wing margin, no loss of wing tissue is seen in non-margin areas.
Heterozygous Klp64Dk1 mutant flies do not exhibit any wing phenotypes.
About 17.7% of null mutant Klp64Dk1 embryos show severe segment polarity phenotypes. Ectopic denticles are formed in the space between normal denticle belts.
The average peak electroantennogram response is reduced in Klp64Dk1/Klp64Dl4 and Klp64Dk5/Klp64Dk1 adults compared to controls (in response to ethyl acetate, n-butanol, benzaldehyde or propionic acid).
The average cilia volume is reduced in mutant adults compared to wild type in sensilla basiconica and sensilla trichodea of the antennae.
The outer segments of the basiconic cilia of the sensilla basiconica of the antenna are less branched than normal in Klp64Dk5/Klp64Dk1 adults.
The length and volume expansions of both the basiconic and trichoid cilia are reduced at the second stage of cilia growth in Klp64Dk1/Klp64Dk1 and Klp64Dk1/Klp64Dl4 antennae compared to wild type.
In mutant animals, accumulation of microtubules is seen at the cilia base of ciliated cells.
Klp64Dk1/Klp64Dn123 mutants lack cilia in the chordotonal organs.
Klp64Dk1/Klp64Dk5 homozygotes have a reduced auditory response, producing a severely reduced sound evoked potentials from the Johnston's organ neurons. In Klp64Dk1/Klp64Dn123 mutant animals, the sensory cilia from Johnston's organ are absent, but inner-dendritic segment and desmosomal junctions appear normal.
Homozygotes die at or before the early third larval instar stage in a typical crowded culture. If the homozygotes are raised in low density conditions without competition from wild-type larvae, a few mutant animals survive to be pharate pupae and occasionally eclose as fully formed adults. The adults show an acutely uncoordinated walk, are unable to stand and die in a few hours. Mutant third instar larvae show slight to severe sluggishness and roll abnormally from side to side during crawling.
Klp64Dk1/Klp64Dn123 has lethal phenotype, suppressible by Mmus\Kif3aUAS.cRa/Scer\GAL4elav.PLu
Klp64Dk1, arm1/arm[+] has wing margin phenotype
Klp64Dk1, arm1/arm[+] has wing margin bristle phenotype
Klp64Dk1, dsh3/dsh[+] has wing margin phenotype
Klp64Dk1, dsh3/dsh[+] has wing margin bristle phenotype
One copy of Klp64Dk1 is unable to enhance the wing notching seen in Nnd-3 heterozygotes.
One copy of Klp64Dk1 is unable to enhance the wing notching seen in N264-40 heterozygotes.
In contrast to either mutation alone, more than 50% of flies heterozygous for Klp64Dk1 and arm1 show significant loss of wing bristles and wing margin notching.
In contrast to either mutation alone, flies heterozygous for Klp64Dk1 and dsh3 show loss of wing bristles and wing margin notching.
The lethality of Klp64Dk1/Klp64Dn123 flies is completely rescued by Mmus\Kif3aScer\UAS.cRa expressed under the control of Scer\GAL4elav.PLu.
Klp64Dk1 is rescued by Klp64DUAS.GFP/Scer\GAL4SG18.1
Klp64Dk1 is rescued by Klp64DUAS.GFP/Scer\GAL4ChAT.7.4
Klp64Dk5/Klp64Dk1 is rescued by Scer\GAL4da.G32/Klp64DUAS.cRa
Klp64Dk1/Klp64Dn123 is rescued by Klp64DUAS.cRa
Klp64Dk1 is rescued by Klp64DUAS.cRa
Expression of Klp64DScer\UAS.cRa under the control of Scer\GAL4da.G32 rescues the reduced electroantennogram response of Klp64Dk5/Klp64Dk1 adults in response to ethyl acetate, n-butanol, benzaldehyde or propionic acid.
Expression of Klp64DScer\UAS.T:Avic\GFP under the control of either Scer\GAL4SG18.1 or Scer\GAL4Cha.7.4 rescues the reduced electroantennogram response of homozygous Klp64Dk1 adults in response to ethyl acetate, n-butanol, benzaldehyde or propionic acid.
Klp64DScer\UAS.cRa rescues the lethality and uncoordinated behaviour of Klp64Dk1, either in homozygous condition or in transheterozygous combination with Klp64Dn123, in the absence of a Scer\GAL4 driver.
