Isolation of larval behavioral mutants in Drosophila melanogaster.
Genetic loci that influence behavior are often difficult to identify and localize in part due to the quantitative nature of behavioral phenotypes. Previous studies had found an association between pupal lethality and altered larval behavior for mutants of several genes. To facilitate the identification and localization of new mutants that influence larval foraging (movement in the presence of f...
متن کاملBehavioral Mutants of DROSOPHILA MELANOGASTER. I. Isolation and Mapping of Mutations Which Decrease Flight Ability.
A flight test box was developed and used in the isolation and initial characterization of Drosophila melanogaster mutants defective in flight behavior. Forty-eight mutants were isolated from F(1) progeny of ethyl methanesulfonate-treated males. Genetic mapping and complementation tests show that the mutations reside at thirty-four different sites on the X chromosome. Different mutants show diff...
متن کاملA method for fate mapping the foci of lethal and behavioral mutants in Drosophila melanogaster.
A new method of mosaic fate mapping, called focusing, is introduced. Its advantages are that it allows a mapping, on the blastoderm surface, of the site of action of functions defined by either pre-adult lethal or behavioral mutations. Moreover, it does not require that the mosaics used be 50% of one genotype and 50% of the other. Methods for quantitative evaluation of the results of focusing, ...
متن کاملSpectral analysis of courtship songs in behavioral mutants of Drosophila melanogaster.
Spectral analyses were applied to the courtship songs of the mutants cacophony (cac), dissonance (diss), fruitless (fru), and period (per), as well as to the double mutant cac diss. Aberrant intervals between song pulses were observed in diss, cac, cac diss, and fru songs. diss males displayed a defect in song hums manifested by an irregular sine wave, although the fundamental frequencies were ...
متن کاملSleep Restores Behavioral Plasticity to Drosophila Mutants
Given the role that sleep plays in modulating plasticity, we hypothesized that increasing sleep would restore memory to canonical memory mutants without specifically rescuing the causal molecular lesion. Sleep was increased using three independent strategies: activating the dorsal fan-shaped body, increasing the expression of Fatty acid binding protein (dFabp), or by administering the GABA-A ag...
