'The All-Species Living Tree' Project

Collaborative academic project February 2021 June 2025 thumb|right|'The All-Species Living Tree' Project logo The All-Species Living Tree' Project (LTP) 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.

Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea.Wu Dongying Hugenholtz Philip Mavromatis Konstantinos Pukall Rüdiger Dalin Eileen Ivanova Natalia N.
