An ITS-based phylogenetic framework for the genus Vorticella: finding the molecular and morphological gaps in a taxonomically difficult group.
Vorticella includes more than 100 currently recognized species and represents one of the most taxonomically challenging genera of ciliates. Molecular phylogenetic analysis of Vorticella has been performed so far with only sequences coding for small subunit ribosomal RNA (SSU rRNA); only a few of its species have been investigated using other genetic markers owing to a lack of similar sequences ...
متن کاملPhylogenetic relationships and taxonomy of the Leptogium lichenoides group (Collemataceae, Ascomycota) in Europe
Leptogium (Ach.) Gray is a cosmopolitan genus of lichen-forming ascomycetes classified in the Collemataceae and represented by c. 250 species with about 40 infrageneric taxa found in Europe (Aragón & al., 2005). Several complexes have been studied within this morphologically and anatomically heterogeneous genus by different authors (Jørgensen, 1975, 1994, 1997; Jørgensen & James, 1983; Jørgense...
متن کاملA phylogenetic study of the Lecanora rupicola group (Lecanoraceae, Ascomycota).
A molecular phylogeny of the Lecanora rupicola group is presented, based on ITS sequence analyses. The study includes saxicolous and corticolous members of the Lecanora rupicola group as well as other Lecanora species with pruinose apothecia. A phylogenetic hypothesis for species in Lecanora s. lat. and various other genera in Lecanoraceae, based on an alignment-free distance estimation techniq...
متن کاملTowards a Taxonomically Intelligent Phylogenetic Database
This note outlines some of the key intellectual obstacles that stand in the way of creating a usable phylogenetic database. These challenges include the need to accommodate multiple taxonomic names and classifications, and the need for tools to query trees in biologically meaningful ways. Until these problems are addressed, and a taxonomically intelligent phylogenetic database created, much of ...
متن کاملCharacterisation and phylogenetic relationships of Anisogramma virgultorum and A. anomala in the Diaporthales (Ascomycota).
The two diaporthalean fungi Anisogramma virgultorum and A. anomala are biotrophic parasites. A. virgultorum causes stromatal cankers on young shoots of birch whereas A. anomala infects young branches of Corylus avellana. Although previous classifications based on morphological characteristics placed both species in the Gnomoniaceae, Diaporthales, their taxonomic position within the order and th...
