Meta Microbes Online

As of October 2010, contained over 1600 genomes from bacterial, archaeal, and microeukaryotic isolates, offers combined phylogenetic gene tree analysis of millions of genes from over 150 ecological and organismal metagenomes. These trees are built using our FastTree program, which offers rapid highly accurate tree building, even for very large trees. Such combined analysis is superior to BLAST-based homology approaches in that trees offers the ability to place genes from environmental samples into an evolutionary context and permits more precise functional grouping within a gene family and may identify phylogenetic markers to aid in assigning the species for environmental sequence fragments, permitting the determination of which community members are responsible for which roles.
