ry1/ry[+] is an enhancer of chemical sensitive phenotype of Gk1dsRNA.UAS, Scer\GAL4c564
ry1 has phenotype, non-suppressible by su(Hw)2
The glycerol hypersensitivity of flies expressing GykdsRNA.Scer\UAS under the control of Scer\GAL4c564 (seen as a reduction in survival on a glycerol only food source) is enhanced if the flies are also heterozygous for ry1.
