Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
Homozygous neuroblast clones result in a 50% reduction in the number of projection neurons compared to wild type. The mutant cells show a reduced dendritic mass and the dendrites do not target their correct glomeruli.
Homozygous single-cell DL1 projection neuron clones mistarget their dendrites towards dorsomedial (47% of clones) or ventromedial regions (44% of clones) of the antennal lobe (normally the dendrites of this projection neuron project to the dorsolateral glomerulus DL1).
Homozygous DL1 projection neuron clones show an axon overbranching phenotype in the lateral horn, regardless of where the dendrites mistarget.
HDAC112-37 has abnormal neuroanatomy | somatic clone phenotype, suppressible | partially | somatic clone by prosL.UAS/Scer\GAL4GH146

The dendrite targeting and axon arborisation defects seen in Rpd312-37 single-cell DL1 projection neuron clones are not rescued by expression in the mutant clone of Hdac3Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4GH146.
The reduction in cell number seen in Rpd312-37 projection neuron neuroblast clones is not rescued by expression in the mutant clone of Hdac3Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4GH146.
Expression of prosL.Scer\UAS under the control of Scer\GAL4GH146 in DL1 projection neuron clones which are mutant for Rpd312-37 rescues the dendrite mistargeting defects seen in these mutant clones. In addition, the axon overbranching phenotype seen in Rpd312-37 clones is partially but significantly rescued.
HDAC112-37 is partially rescued by HDAC1UAS.Tag:V5/Scer\GAL4GH146
Expression of Rpd3Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GH146 in single-cell DL1 projection neuron clones which are mutant for Rpd312-37 significantly rescues the dendrite mistargeting defects seen in these clones.
Expression of Rpd3Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GH146 in single-cell DL1 projection neuron clones is sufficient to rescue the axon overbranching phenotype in the lateral horn which is seen in these clones.
Expression of Rpd3Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GH146 in projection neuron neuroblast clones which are homozygous for Rpd312-37 does not rescue the reduced cell number seen in these clones.
