The rosy locus in Drosophila melanogaster: xanthine dehydrogenase and eye pigments.

Genetics - 1 Dec 1991

Reaume A G, Knecht D A, Chovnick A

Abstract excerpt

The rosy gene in Drosophila melanogaster codes for the enzyme xanthine dehydrogenase (XDH). Mutants that have no enzyme activity are characterized by a brownish eye color phenotype reflecting a deficiency in the red eye pigment. Xanthine dehydrogenase is not synthesized in the eye, but rather is transported there. The present report describes the ultrastructural localization of XDH in the Drosophila eye. Three...
