Mutational analysis and genetic cloning of the agnostic locus, which regulates learning ability in Drosophila.
P-insertion mutations were obtained and localized by in situ methods at the agnostic gene (agn: 1-38.9; 11AB) in Drosophila. All agn mutants showed a wide spectrum of pleiotropic effects: an EMS-induced mutation of the agn-ts398 improved the ability to develop a conditioned defensive response and increased the activity of cAMP metabolic enzymes; spontaneous mutation of agnX1 showed morphological defects of the brain. P-insertion mutations were used to clone the gene; a restriction map of 80 kb in length was determined, and the insertion was localized to a fragment of 9 kb.
