Accounting for Gene Rate Heterogeneity in Phylogenetic Inference

newsdigg submitted, created time 1 year 8 months (www.informaworld.com)

Traditionally, phylogenetic analyses over many genes combine data into a contiguous block. Under this concatenated model, all genes are assumed to evolve at the same rate. However, it is clear that genes evolve at very different rates and that accounting for this rate heterogeneity is important if we are to accurately infer phylogenies from heterogeneous multigene data sets. There remain open questions regarding how best to incorporate gene rate parameters into phylogenetic models and which properties of real data correlate with improved fit over the concatenated model

Phylemon: a suite of web tools for molecular evolution, phylogenetics and phylogenomics

channel submitted, created time 1 year 8 months (nar.oxfordjournals.org)

The Phylemon web server is available at http://phylemon.bioinfo.cipf.es. Phylemon is an online platform for phylogenetic and evolutionary analyses of molecular sequence data. It has been developed as a web server that integrates a suite of different tools selected among the most popular stand-alone programs in phylogenetic and evolutionary analysis. It has been conceived as a natural response to the increasing demand of data analysis of many experimental scientists wishing to add a molecular evolution and phylogenetics insight into their research.
