TranscriptomicsPopulation- and sex-biased gene expression in the excretion organs of Drosophila melanogaster
We used RNA-seq to investigate gene expression variation in Malpighian tubules, which have a function analogous to that of human kidneys. In order to characterize population differentiation, we sequenced the Malpighian tubule transcriptomes of flies derived from two populations, one from sub-Saharan...

TranscriptomicsPopulation and sex differences in Drosophila melanogaster brain gene expression
Background: Changes in gene regulation are thought to be crucial for the adaptation of organisms to their environment. Transcriptome analyses can be used to identify candidate genes for ecological adaptation, but can be complicated by variation in gene expression between tissues, sexes, or individua...

TranscriptomicsGene expression variation in African and European populations of Drosophila melanogaster
Background: Differences in levels of gene expression among individuals are an important source of phenotypic variation within populations. Recent microarray studies have revealed that expression variation is abundant in many species, including Drosophila melanogaster. However, previous expression su...
