Detailed Description
Statement
Reference

Flies carrying axed2094 mutant somatic clones show defective injury-induced axon degeneration: severed axons (either in sensory neurons in the wing or in cholinergic olfactory receptor neurons) remain intact for a full week after an axotomy (or even 50 days in the latter case), instead of being cleared away. After axotomy of mechanosensory neurons in the Johnston's organ, the persisting severed axons can still elicit grooming behavior upon optogenetic stimulation of the neurons.

axed2094 is a non-suppressor of eye phenotype of hidGMR.PG

Additional Comments
Genetic Interactions
Statement
Reference

MARCM clones in sensory neurons in the adult wing expressing Ect4ΔARM.Scer\UAS.T:Hsap\MYC driven by Scer\GAL4VGlut-OK371 undergo spontaneous cell body and axon degeneration which can be suppressed by combination with axed2094.

The axon and cell body degeneration in sensory neuron clones in the adult wing mutant for NmnatΔ4790-1 or expressing NmnatGD8082 under the control of Scer\GAL4VGlut-OK371 can be fully rescued by combination with axed2094 or by axed2094 and Ect4896 together.

The NmnatΔ4790-1,axed2094 double mutant clones display defective injury-induced axon degeneration (severed axons remain intact following an axotomy, instead of being cleared away) which cannot be overcome by expressing Ect4ΔARM.Scer\UAS.T:Hsap\MYC under the Scer\GAL4VGlut-OK371 driver in the mutant clones.

The small eye phenotype resulting from the cell death induced by expression of hidGMR.PG is not suppressed by combination with axed2094.

Comments

The defective injury-induced axon degeneration observed in flies carrying axed2094 mutant neural clones (severed axons in sensory neurons in the adult wing remain intact following an axotomy, instead of being cleared away) can be rescued by clonal Scer\GAL4VGlut-OK371-driven expression of any of the following: axedScer\UAS.long, axedΔBTB.Scer\UAS, axedΔBACK.Scer\UAS or axedΔCterm.Scer\UAS.

Any of the following: axed0011, axedCrisprA, axedCrisprB, axedCrisprC, axedEx07, axedEx65 or axedEx96 fails to complement the lethality of axed2094 mutants, while Ect4896 fails to do so.
