      The expression of fraΔC.UAS.Tag:HA under the control of Scer\GAL4Pdf.PU results in adult sLNv neurons exhibiting significantly shorter axons compared to controls.

      (Oliva et al., 2016)

      Expression of a weak transgene of fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu does not cause any defects in axon midline crossing.

      (O'Donnell and Bashaw, 2013)

      Expression of fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360 generates midline crossing defects, with most (approx. 90%) eg-axons mis-projecting.

      (O'Donnell and Bashaw, 2013)

      Neuronal expression of fraΔC.Scer\UAS.T:Ivir\HA under the control of Scer\GAL4eg-Mz360 leads to a dose dependent "commissureless" phenotype.

      (Yang et al., 2009)

      Overexpression of one copy of fraΔC.Scer\UAS.T:Ivir\HA under the control of Scer\GAL4elav.PLu causes commissures to become thin. Axon commissures are almost completely absent when two copies of fraΔC.Scer\UAS.T:Ivir\HA are expressed.

      The severity of the embryonic commissure phenotype resulting from the overexpression of one copy of fraΔC.Scer\UAS.T:Ivir\HA under the control of Scer\GAL4elav.PLu increases in fraunspecified heterozygotes. Homozygous fraunspecified mutants overexpressing one copy of fraΔC.Scer\UAS.T:Ivir\HA exhibit a near complete loss of axon commissures.

      Expression of fraΔC.Scer\UAS.T:Ivir\HA under the control of Scer\GAL4eg-Mz360 causes a decrease of EW attraction towards the midline, though in many segments the EW neurons cross normally. When fraScer\UAS.T:Myr1.T:Hsap\MYC is expressed in fraunspecified homozygous embryos, none of the EW neurons cross the midline. In some segments, EG axon guidance is also defective, a phenotype never observed in fraunspecified mutants.

      Expression of a weak transgene of fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360 has no effect on the number and severity of midline crossing defects found in Abl2 homozygous mutants. The presence of AblScer\UAS.T:Avic\GFP reduces the number of midline crossing defects (to a statistically significant level) in Abl2 homozygous mutants in a fraΔC.Scer\UAS.T:Ivir\HA1-expressing background. The presence of AblK417N.Scer\UAS.T:Avic\GFP reduces (although not to a statistically significant level) the number of midline crossing defects in Abl2 homozygous mutants in a fraΔC.Scer\UAS.T:Ivir\HA1-expressing background.

      Expression of AblΔFABD.Scer\UAS.T:Avic\GFP in EW neurons, under the control of Scer\GAL4eg-Mz360 fails to rescue EW midline-crossing defects in Abl2 neurons expressing fraΔC.Scer\UAS.T:Ivir\HA1.

      (O'Donnell and Bashaw, 2013)

      A Src42Ak10108 heterozygous background partially suppresses the eg-positive neuron midline crossing defects found upon expression of fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360.

      A Src64Bko heterozygous background partially suppresses the eg-positive neuron midline crossing defects found upon expression of fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360.

      A Src42Ak10108/+ ; Src64Bko/+ trans-heterozygous background partially suppresses the eg-positive neuron midline crossing defects found upon expression of fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360.

      Src42Ak10108/+;Src64Bko heterozygous background suppresses the eg-positive neuron midline crossing defects found upon expression of fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360.

      Co-expression of Src64BYF.Scer\UAS with fraΔC.Scer\UAS.T:Ivir\HA1 in eg-expressing neurons, under the control of Scer\GAL4eg-Mz360 enhances the midline crossing defects found when fraΔC.Scer\UAS.T:Ivir\HA1 alone is expressed under the control of Scer\GAL4eg-Mz360.

      A unc-52 heterozygous background increases the percentage of embryonic segments displaying eg-positive axon midline crossing defects in flies expressing fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360. However, this increase isn't considered statistically significant.

      A mys1/Y background increases the percentage of embryonic segments displaying eg-positive axon midline crossing defects in flies expressing fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360. However, this increase isn't considered statistically significant.

      A robo1 homozygous background increases the percentage of embryonic segments displaying eg-positive axon midline crossing defects in flies expressing fraΔC.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4eg-Mz360. However, this increase isn't considered statistically significant.

      (O'Donnell and Bashaw, 2013)

      The midline crossing defects of axons seen in Scer\GAL4eg-Mz360-driven fraΔC.Scer\UAS.T:Ivir\HA-expressing embryos are enhanced in a heterozygous communspecified/+ genetic background.

      (Yang et al., 2009)

      Expression of fraΔC.Scer\UAS.T:Ivir\HA driven by Scer\GAL4elav.PLu does not cause a commissureless phenotype in either Df(1)NP5 or Df(1)NetABΔ mutant background.

      Expression of fraΔC.Scer\UAS.T:Ivir\HA driven by Scer\GAL4elav.PLu still causes a commissureless phenotype in a fraunspecified unc-5unspecified double mutant background.

      Expression of fraΔC.Scer\UAS.T:Ivir\HA driven by Scer\GAL4elav.PLu in a fraunspecified sli2 double mutant background results in a phenotype similar to the phenotype observed for overexpression of fraΔC.Scer\UAS.T:Ivir\HA in a fraunspecified single mutant background, where many axons fail to cross the midline.

      Expression of fraΔC.Scer\UAS.T:Ivir\HA driven by Scer\GAL4elav.PLu in a fraunspecified robo1 double mutant background dramatically repels axons, though the defect is less severe than seen in a fraunspecified single mutant background.

      Expression of fraΔC.Scer\UAS.T:Ivir\HA driven by Scer\GAL4elav.PLu leads to a partial suppression of the robo1 single mutant phenotype.
