Phylogeny reconstruction using duplicate genes.
In this paper, we propose a new method (uninode coding) for coding duplicate (paralogous) genes to infer species trees. Uninode coding incorporates data from duplicated and unduplicated gene copies in phylogenetic analyses of taxa. Uninode coding utilizes global parsimony through the inclusion of both duplicated and unduplicated gene copies, allows one to code all data sources from a taxon into...
متن کاملThe root of angiosperm phylogeny inferred from duplicate phytochrome genes.
An analysis of duplicate phytochrome genes (PHYA and PHYC) is used to root the angiosperms, thereby avoiding the inclusion of highly diverged outgroup sequences. The results unambiguously place the root near Amborella (one species, New Caledonia) and resolve water lilies (Nymphaeales, approximately 70 species, cosmopolitan), followed by Austrobaileya (one species, Australia), as early branches....
متن کاملExpression divergence between duplicate genes.
A general picture of the role of expression divergence in the evolution of duplicate genes is emerging, thanks to the availability of completely sequenced genomes and functional genomic data, such as microarray data. It is now clear that expression divergence, regulatory-motif divergence and coding-sequence divergence all increase with the age of duplicate genes, although their exact interrelat...
متن کاملStratigraphy in Phylogeny Reconstruction
Beginning with this issue, the Journal of Paleontology will be publishing an occasional section entitled ‘‘View from the Field’’. ‘‘View from the Field’’ will provide a forum for concise commentary on current issues in paleontology, including but not limited to discussion of methods, important new discoveries, and major conceptual advances. Contributions should be brief (no more than 12 double-...
متن کاملMolecular Phylogeny Reconstruction
Molecular phylogenetics deals with the inference of evolutionary relationships among individuals, populations, species and higher taxonomic entities using molecular data. Bymodelling patterns ofmolecular change in protein anddeoxyribonucleic acid (DNA) sequences over time, scientists now routinely reconstruct evolutionary histories of species and evaluate confidence levels of the inferences. Mo...
