Genetic analysis of chemosensory pathway
- 103 Downloads
Some olfactory and gustatory mutants ofDrosophila melanogaster are described. Theolf mutants are insensitive to the repellent, benzaldehyde or the attractant ethyl acetate or simultaneously to both. Thegust mutants are unable to taste quinine or NaCl or sucrose. Electrophysiological tests show that one of the sugar non-tasters has an altered primary chemoreceptor response to sucrose.
