Welcome to the Phylogenomics Laboratory of the Virginia Bioinformatics Institute (VBI) at Virginia Tech. This site provides an interface to databases and analysis methods designed to explore the global phylogenetic patterns of gene homology groups within and across species. GeneTrees consists of several databases of pre-compiled alignments and gene phylogenies for a variety of taxonomic groups. Within each taxonomic group, genome-scale sequences have been globally searched for mutually consistent conserved homology groups.

Taxon-Specific Databases

• Prokaryote 325 fully sequenced prokaryotic genomes.
• Viral Protein sequences from many complete viral genomes.
• Stramenopiles Protein sequences from several eukaryote organisms related to oomycetes.
