Functional Evolution of cis-Regulatory Modules at a Homeotic Gene in Drosophila [PDF]
It is a long-held belief in evolutionary biology that the rate of molecular evolution for a given DNA sequence is inversely related to the level of functional constraint.

Revealing posttranscriptional regulatory elements through network-level conservation. [PDF]
We used network-level conservation between pairs of fly (Drosophila melanogaster/D. pseudoobscura) and worm (Caenorhabditis elegans/C. briggsae) genomes to detect highly conserved mRNA motifs in 3' untranslated regions.

Krüppel Expression Levels Are Maintained through Compensatory Evolution of Shadow Enhancers
Many developmental genes are controlled by shadow enhancers—pairs of enhancers that drive overlapping expression patterns. We hypothesized that compensatory evolution can maintain the total expression of a gene, while individual shadow enhancers diverge ...

RepeatOBserver: Tandem Repeat Visualisation and Putative Centromere Detection
ABSTRACT Tandem repeats play an important role in centromere structure, subtelomeric regions, DNA methylation, recombination and the regulation of gene activity. Analysis of their distribution in genomes offers a potential means for predicting putative centromere locations, which continues to be a challenge for genome annotation.

Determinants of mating success in a lek‐mating species
Abstract Leks are male‐biased aggregations formed for mating, where sperm is the only resource acquired by visiting females. One of the many advantages of leks is the possibility to efficiently assess the quality of potential mates by comparing aggregated individuals of the same sex with one another. When direct mate choice occurs in a lekking species,

Complex Evolutionary History of the Y Chromosome in Flies of the Drosophila obscura Species Group. [PDF]
The Drosophila obscura species group shows dramatic variation in karyotype, including transitions among sex chromosomes. Members of the affinis and pseudoobscura subgroups contain a neo-X chromosome (a fusion of the X with an autosome), and ancestral Y ...

We have sequenced the genome of a second Drosophila species, Drosophila pseudoobscura, and compared this to the genome sequence of Drosophila melanogaster, a primary model organism. Throughout evolution the vast majority of Drosophila genes have remained

A recombinational portrait of the Drosophila pseudoobscura genome
Drosophila pseudoobscura has been intensively studied by evolutionary biologists for over 70 years. The recent publication of the genome sequence not only permits studies of comparative genomics with other dipterans but also opens the door to identifying genes associated with adaptive traits or speciation or testing for the signature of natural ...
