Phenotypic Data

Phenotypic Class

abnormal neuroanatomy | adult stage | male, with Scer\GAL4^Poxn.14

(Mellert et al., 2010)

Phenotype Manifest In

prothoracic leg taste bristle chemosensory neuron | male, with Scer\GAL4^Poxn.14

(Mellert et al., 2010)

Detailed Description

Statement

Reference

The expression of robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^Pdf.PU does not significantly affect the length of sLNv axons compared to controls.

(Oliva et al., 2016)

Females expressing robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^Poxn.14 do not show midline crossing by foreleg gustatory receptor neuron (GRN) axons (this phenotype is the same as in wild-type females). Males expressing robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^Poxn.14 show reduced midline crossing by foreleg GRNs compared to that seen in control males.

(Mellert et al., 2010)

Expression of a single copy of robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^elav-C155 or Scer\GAL4^sca-375.1 has no effect on visual system development.

Statement

Reference

The co-expression of robo3^{dsRNA.Scer\UAS} and robo2^{dsRNA.Scer\UAS}, but not of robo3^{dsRNA.Scer\UAS} and robo1^{dsRNA.Scer\UAS}, under the control of Scer\GAL4^Pdf.PU results in adult sLNv neurons exhibiting significantly longer axon projections compared to controls.

(Oliva et al., 2016)

Males and females simultaneously co-expressing robo^{dsRNA.Scer\UAS}, lea^{dsRNA.Scer\UAS} and robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^Poxn.14 show severe disruption of foreleg gustatory receptor neuron axon morphology, with axons collapsing onto the midline.

(Mellert et al., 2010)

Simultaneous co-expression of robo^{dsRNA.Scer\UAS}, lea^{dsRNA.Scer\UAS} and robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^elav-C155 results in defects in visual system development; distal cell neurons invade the developing lamina. Simultaneous co-expression of robo^{dsRNA.Scer\UAS}, lea^{dsRNA.Scer\UAS} and robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^sca-375.1 results in distal cell neurons invading the developing lamina. The distal cell neurons and lamina glia are intermingled in these animals. In addition defects in photoreceptor axon targeting are seen, with the regions of mistargeting correlating with the regions where the distal cell neurons enter the lamina. Co-expression of two copies of robo^{dsRNA.Scer\UAS} and two copies of robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^sca-375.1 results in modest defects in the visual system. Simultaneous co-expression of robo^{dsRNA.Scer\UAS}, lea^{dsRNA.Scer\UAS} and robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^αTub84B.PL results in many photoreceptor axons extending through the lamina and too many photoreceptor axons entering the medulla. Simultaneous co-expression of robo^{dsRNA.Scer\UAS}, lea^{dsRNA.Scer\UAS} and robo3^{dsRNA.Scer\UAS} under the control of Scer\GAL4^GMR.PF does not result in any defects in photoreceptor axon targeting.
