'The All-Species Living Tree' Project

From Wikipedia, the free encyclopedia
Jump to: navigation, search

'The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB, SILVA rRNA database project, and LPSN, with the aim of assembling a database of 16S rRNA sequences of all validly published species of Bacteria and Archaea.[1] At one stage, 23S sequences were also collected,[2] but this has since stopped.[3]

Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species.

Tree[edit]

See also: Bacterial phyla

The tree was created by ML without bootstrap: consequently accuracy is traded off for size and many phylum level clades are not correctly resolved (such as the Firmicutes). (Eukaryotes not present in analysis). This 16S rRNA-based phylogenetic tree is based on the ARB-SILVA release LTPs 121 (June 2015)[4][5] and contains all type species with validly published names.
