Welcome to mor


mor is an ongoing project based in the Hibbett lab of Clark University that seeks to produce continually updated phylogenetic trees and classifications for the homobasidiomycetes (mushroom-forming fungi) on an automated basis. In brief, mor retrieves, screens, aligns, and analyzes nuc-lsu rDNA sequences of homobasidiomycetes from GenBank, and then parses out the contents of individual clades using node-based phylogenetic taxon definitions. Thus, mor represents a step toward automated phylogenetic taxonomy. For more information about homobasidiomycete phylogeny, visit the Tree of Life Web Project page for homobasidiomycetes.

mor creates three phylogenetic trees each week: an unconstrained jacknife neighbor-joining tree, a topologically constrained consensus maximum parsimony tree and a topologically constrained maximum likelihood tree. The parsimony tree is used to delimit the clades. On the following pages, you can view the NJ, MP and ML trees, link to GenBank, search for images of fungi on the internet, view individual clade pages, download alignments and treefiles (for the entire dataset or individual clades), post comments, and create new clade definitions. Please note that some files are quite large (about 6 MB) and can take some time to load.

sequences in the database

Take a look at the sequences that mor has already analyzed. You can view either the accepted or rejected sequences organized by the species name, the accession number, or the date they were added.
