Parallel reorganization of protein function in the spindle checkpoint pathway through evolutionary paths in the fitness landscape that appear neutral in laboratory experiments. [PDF]
Regulatory networks often increase in complexity during evolution through gene duplication and divergence of component proteins. Two models that explain this increase in complexity are: 1) adaptive changes after gene duplication, such as resolution of ...

Gene duplication and an accelerated evolutionary rate in 11S globulin genes are associated with higher protein synthesis in dicots as compared to monocots [PDF]
Background: Seed storage proteins are a major source of dietary protein, and the content of such proteins determines both the quantity and quality of crop yield.

Background: Very few reports are available on human XX ovotesticular disorder of sex development involving SOX3 gene duplication. Here we aim to present a rare case of SOX3 gene duplication in a person from the Chinese population who exhibits XX ...

Complexity Insights of the Minimum Duplication Problem [PDF]
International audienceThe Minimum Duplication problem is a well-known problem in phylogenetics and comparative genomics. Given a set of gene trees, the Minimum Duplication problem asks for a species tree that induces the minimum number of gene ...

The multiple gene duplication problem revisited [PDF]
Motivation: Deciphering the location of gene duplications and multiple gene duplication episodes on the Tree of Life is fundamental to understanding the way gene families and genomes evolve.

Mitochondrial targeting adaptation of the hominoid-specific glutamate dehydrogenase driven by positive Darwinian selection [PDF]
Many new gene copies emerged by gene duplication in hominoids, but little is known with respect to their functional evolution. Glutamate dehydrogenase (GLUD) is an enzyme central to the glutamate and energy metabolism of the cell.

Altered patterns of gene duplication and differential gene gain and loss in fungal pathogens
Background Duplication, followed by fixation or random loss of novel genes, contributes to genome evolution. Particular outcomes of duplication events are possibly associated with pathogenic life histories in fungi.

Tandem duplications lead to novel expression patterns through exon shuffling in Drosophila yakuba. [PDF]
One common hypothesis to explain the impacts of tandem duplications is that whole gene duplications commonly produce additive changes in gene expression due to copy number changes.

Almost all human genes resulted from ancient duplication [PDF]
Results of protein sequence comparison at open criterion show a very large number of relationships that have, up to now, gone unreported. The relationships suggest many ancient events of gene duplication. It is well known that gene duplication has been a

Efficient Exploration of the Space of Reconciled Gene Trees [PDF]
Gene trees record the combination of gene level events, such as duplication, transfer and loss, and species level events, such as speciation and extinction.
