Phylogeny: Rewriting evolution

Query Rewriting Under Ontology Evolution

One of the most prominent reasoning techniques for query answering is query rewriting. The last years a wide variety of query rewriting systems has been proposed. All of them accept as input a CQ Q and a fixed ontology O and produce a rewriting for Q, O. However, in many real world applications ontologies are very often dynamic—that is, new axioms can be added or existing ones removed frequentl...

Brassicaceae phylogeny and trichome evolution.

To estimate the evolutionary history of the mustard family (Brassicaceae or Cruciferae), we sampled 113 species, representing 101 of the roughly 350 genera and 17 of the 19 tribes of the family, for the chloroplast gene ndhF. The included accessions increase the number of genera sampled over previous phylogenetic studies by four-fold. Using parsimony, likelihood, and Bayesian methods, we recons...

Eumetazoan Cryptochrome Phylogeny and Evolution

Cryptochromes (Crys) are light sensing receptors that are present in all eukaryotes. They mainly absorb light in the UV/blue spectrum. The extant Crys consist of two subfamilies, which are descendants of photolyases but are now involved in the regulation of circadian rhythms. So far, knowledge about the evolution, phylogeny, and expression of cry genes is still scarce. The inclusion of cry sequ...

Evolution of Sleep (Sleep Phylogeny)

Apolipoprotein E phylogeny and evolution.

Among apolipoproteins, apolipoprotein E (Apo E) plays a pivotal role in lipid transport and is proposed to be involved in neural repair. Because of a long divergence history of apolipoproteins, it is unclear how Apo E evolved in time. To investigate relationships among Apo E proteins, we used the information from molecular data and analysed the phylogeny of Apo E proteins from various species. ...
