Database Description

TreeBASE is a relational database of phylogenetic information hosted by the State University of New York at Buffalo. TreeBASE is a community resource that stores phylogenetic trees and the data matrices used to generate them from published research papers. We encourage biologists to submit phylogenetic data that are either published or in press, especially if these data were not fully presented in the publication due to space limitations. TreeBASE accepts all types of phylogenetic data (e.g., trees of species, trees of populations, trees of genes) representing all biotic taxa. Presently TreeBASE is being mirrored at the San Diego Supercomputer Center at UCSD.

Recent Developments

TreeBASE development is now occurring under the auspices of the NSF-sponsored ITR project Cyberinfrastructure for Phylogenetic Research (CIPRES: As such, it is being redesigned from the ground up through a collaborative research effort by Computer Scientists, Biologists, and Database Developers. The redesigned, version of TreeBASE (codenamed Treebase2) is expected to be released in beta form in early 2006. It will feature a new schema that represents trees explicitly as nodes and edges, making complex tree comparisons possible. It will also permit more complex queries across all data, new administrative forms that simplify the submission process, and a commercial relational Database management system that is SQL compliant.

We are grateful to Drs Michael Donoghue, Junhyong Kim, Brent Mishler, Wayne Maddison, Shirley Cohen, and other members of CIPRES project for their expert advice. TreeBASE is currently supported by the National Science Foundation NSF EF 04-51824; EF 04-51657; and NSF EF 04-51721.
