rho gene expression is driven by an Hsp70 promoter.
Homozygous insertions cause a moderate extra-vein phenotype at 25oC.
Flies carrying rhoMod have ectopic wing vein material.
One copy causes a short ectopic segment of vein between wing veins L3 and L4 near the margin and slight L3 and L4 deltas.
In the absence of heat induction individuals display a moderate constitutive excess vein phenotype. Homozygous phenotype is strongly suppressed by heterozygous rhove-1.
rhoMod has phenotype, non-enhanceable by btl::EgfrMod
rhoMod is a non-enhancer of phenotype of btl::EgfrMod
rhoMod/+; btl::EgfrMod/+ double heterozygotes show no enhancement of the extra vein phenotype.
Phenotype dependent on site of insertion of P{HS-rho} into the genome.
