The east gene of Drosophila melanogaster is expressed in the developing embryonic nervous system and is required for normal olfactory and gustatory responses of the adult.

Abstract excerpt

Drosophila melanogaster larvae and adults respond to a wide range of chemosensory stimuli. We describe the genetics and developmental expression of the east gene, mutations which result in adult-specific chemosensory defects. The original isolate of east is semidominant for the behavioral phenotype. Several mutations have been generated, some of which are recessive lethals and others that are viable alleles that...
