Building the Tree of Life, Genome by Genome

Phylogenetic studies have gone 'omic. Whereas researchers used to be satisfied comparing one gene, or a few, to sort out the branching of the tree of life, the push now among those building phylogenies is to consider whole genomes--at the very least, dozens of genes and thousands of DNA bases--in establishing kinships among flora and fauna. In this way, evolutionary biology is joining the bandwagon of data-intensive studies pioneered by genomics

Cophenetic correlation analysis as a strategy to select phylogenetically informative proteins

007RA submitted, created time 1 year 3 months (www.biomedcentral.com)

"This study provides candidate protein sequences to be considered as phylogenetic markers in different branches of fungal TOL. The selection procedure described here will be useful to select informative protein sequences to resolve branches of TOL that contain few or no species with completely sequenced genomes. "
