BMC Genomics, 2003 Background Non-coding DNA represents a high proportion of all metazoan genomes. Although an undetermined fraction of this DNA may be considered devoid of any function, it also contains important information residing in specific cis-regulatory sequences ...

High frequency of microsatellites in Drosophila pseudoobscura.
Genes & Genetic Systems, 2000 Using 30,000 bp of anonymous sequence data, we note that dinucleotide repeat arrays appear to be much more common in Drosophila pseudoobscura than in D. melanogaster or D. simulans. Repeat arrays bearing five or more units are situated on average once every 3000 bp in D. pseudoobscura, and repeat arrays bearing ten or more units are situated on average

Time in a bottle: the evolutionary fate of species discrimination in sibling Drosophila species. [PDF]
PLoS ONE, 2012 Disadvantageous hybridization favors the evolution of prezygotic isolating behaviors, generating a geographic pattern of interspecific mate discrimination where members of different species drawn from sympatric populations exhibit stronger preference for

Gene expression clines reveal local adaptation and associated trade-offs at a continental scale [PDF]
, 2016 Local adaptation, where fitness in one environment comes at a cost in another, should lead to spatial variation in trade-offs between life history traits and may be critical for population persistence.

Genome-wide tests for introgression between cactophilic Drosophila implicate a role of inversions during speciation [PDF]
, 2015 K.L. was funded by a junior research fellowship from the National Environmental Research Council, UK (NE/I020288/1, NBAF659).Models of speciation-with-gene-flow have shown that the reduction in recombination between alternative chromosome arrangements ...

Evolution of the sugar receptors in insects
BMC Evolutionary Biology, 2009 Background Perception of sugars is an invaluable ability for insects which often derive quickly accessible energy from these molecules. A distinctive subfamily of eight proteins within the gustatory receptor (Gr) family has been identified as sugar ...

Ancestral polymorphisms in Drosophila pseudoobscura and Drosophila miranda.
Genetics Research, 2011 Ancestral polymorphisms are defined as variants that arose by mutation prior to the speciation event that generated the species in which they segregate. Their presence may complicate the interpretation of molecular data and lead to incorrect phylogenetic

Comparative validation of the D. melanogaster modENCODE transcriptome annotation [PDF]
, 2014 Accurate gene model annotation of reference genomes is critical for making them useful. The modENCODE project has improved the D. melanogaster genome annotation by using deep and diverse high-throughput data.

Embryonic Heat Shock and its Effect on Larval and Adult Performance in Drosophila melanogaster [PDF]
, 2019 Drosophila melanogaster live across a wide latitudinal range, thus resulting in divergence in thermal adaptation between populations. Despite differences in thermal tolerances, the effects of an embryonic thermal stress on development have not been ...
