ABSTRACT

We identified the causal genetic variation for the difference in the thoracic trident pigmentation intensity between two wild-derived strains of Drosophila melanogaster. It was found to be the difference in expression level of ebony, which codes for an enzyme in the melanin-synthesis pathway and has pleiotropic effects on vision and behavior.

INTRASPECIFIC variation in the pattern and intensity of pigmentation exists widely in diverse insect taxa (reviewed in True 2003;...

Single-Locus Latitudinal Clines and Their Relationship to Temperate Adaptation in Metabolic Genes and Derived Alleles in Drosophila melanogaster
Genetics ; ABSTRACT We report a study in Drosophila melanogaster of latitudinal clines for 23 SNPs embedded in 13 genes (Pgi, Gapdh1, UGPase, Pglym78, Pglym87, Eno, Men, Gdh, Sod, Pgk, Mdh1, TreS, Treh) representing various metabolic enzymes. Our samples are from 10 populations spanning latitude from southern
Triglyceride Pools, Flight and Activity Variation at the Gpdh Locus in Drosophila melanogaster
Genetics ; ABSTRACT We have created a set of P-element excision-derived Gpdh alleles that generate a range of GPDH activity phenotypes ranging from zero to full activity. By placing these synthetic alleles in isogenic backgrounds, we characterize the effects of minor and major activity variation on two

Evidence of Spatially Varying Selection Acting on Four Chromatin-Remodeling Loci in Drosophila melanogaster
Genetics ; ABSTRACT The packaging of DNA into proper chromatin structure contributes to transcriptional regulation. This packaging is environment sensitive, yet its role in adaptation to novel environmental conditions is completely unknown. We set out to identify candidate chromatin-remodeling loci that are
Expression Level of sarah, a Homolog of DSCR1, Is Critical for Ovulation and Female Courtship Behavior in Drosophila melanogaster
Genetics ; ABSTRACT To better understand the genetic bases of postmating responses in Drosophila melanogaster females, we screened a collection of P{GS} insertion lines and identified two insertions in sarah (sra), whose misexpression in the nervous system induced high levels of ovulation in virgins. The gene
Natural Genetic Variation in Cuticular Hydrocarbon Expression in Male and Female Drosophila melanogaster
Genetics ; ABSTRACT Cuticular hydrocarbons (CHCs) act as contact pheromones in Drosophila melanogaster and are an important component of several ecological traits. Segregating genetic variation in the expression of CHCs at the population level in D. melanogaster is likely to be important for mate choice and
A cis-regulatory Sequence Within the yellow Locus of Drosophila melanogaster Required for Normal Male Mating Success
Genetics ; ABSTRACT Drosophila melanogaster males perform a courtship ritual consisting of a series of dependent fixed-action patterns. The yellow (y) gene is required for normal male courtship behavior and subsequent mating success. To better characterize the requirement for y in the manifestation of innate
Genomic Analysis of Adaptive Differentiation in Drosophila melanogaster
Genetics ; ABSTRACT Drosophila melanogaster shows clinal variation along latitudinal transects on multiple continents for several phenotypes, allozyme variants, sequence variants, and chromosome inversions. Previous investigation suggests that many such clines are due to spatially varying selection rather
Quantitative Trait Loci With Age-Specific Effects on Fecundity in Drosophila melanogaster
Genetics ; ABSTRACT Life-history theory and evolutionary theories of aging assume the existence of alleles with age-specific effects on fitness. While various studies have documented age-related changes in the genetic contribution to variation in fitness components, we know very little about the underlying
