The period gene of Drosophila carries species-specific behavioral instructions.
We have analyzed and compared the circadian locomotor activity rhythms of Drosophila melanogaster and D.pseudoobscura. The rhythms of D.pseudoobscura are stronger and the periods shorter than those of D.melanogaster. We have also transformed D.melanogaster flies with a hybrid gene containing the coding region of the D.pseudoobscura period (per) gene. Behavioral assays of flies containing this h...
متن کاملThe nonA gene in Drosophila conveys species-specific behavioral characteristics.
The molecular basis of species-specific differences in courtship behavior, a critical factor in preserving species boundaries, is poorly understood. Genetic analysis of all but the most closely related species is usually impossible, given the inviability of hybrids. We have therefore applied interspecific transformation of a single candidate behavioral locus, no-on-transient A (nonA), between D...

PER is a nuclear protein dian clock, we screened chemically mutagenized flies and enters the nuclei of lateral neurons, putative pacefor suppressors or enhancers of the long periods charmaker cells in the brain (Liu et al., 1992; Zerr et al., 1990; acterist...
متن کاملThe timSL Mutant of the Drosophila Rhythm Gene timeless Manifests Allele-Specific Interactions with period Gene Mutants
To identify new components of the Drosophila circadian clock, we screened chemically mutagenized flies for suppressors or enhancers of the long periods characteristic of the period (per) mutant allele perL. We isolated a novel mutant that maps to the rhythm gene timeless (tim). This novel allele, timSL, alters the temporal pattern of perL protein nuclear localization and restores temperature co...
متن کاملNew short period mutations of the Drosophila clock gene per.
Earlier work has indicated that the period length of Drosophila circadian behavioral rhythms is dependent on the abundance of the period (per) gene product. Increased expression of this gene has been associated with period shortening for both the circadian eclosion (pupal hatching) rhythm and circadian locomotor activity rhythms of adult Drosophila. In this study it is shown that a wide variety...
