Journal ArticleDOI
Broadly sampled multigene trees of eukaryotes.
Hwan Su Yoon,Hwan Su Yoon,Jessica R. Grant,Yonas I. Tekle,Min Wu,Benjamin C Chaon,Jeffrey C. Cole,John M. Logsdon,David J. Patterson,Debashish Bhattacharya,Laura A. Katz +10 more
TL;DR: The analytical approach substantiates the power of increased taxon sampling in placing diverse eukaryotic lineages within well-supported clades and indicates that the six supergroup hypothesis of higher-level eucaryotic classification is likely premature.
Journal ArticleDOI
Barcoding ciliates: a comprehensive study of 75 isolates of the genus Tetrahymena.
Chitchai Chantangsi,Denis H. Lynn,Maria T. Brandl,Jeffrey C. Cole,Neil D. Hetrick,Pranvera Ikonomi +5 more
TL;DR: The feasibility of using the mitochondrial cox1 gene as a taxonomic marker for 'barcoding' and identifying Tetrahymena species and some other ciliated protists is demonstrated.
Journal ArticleDOI
Phylogenetic placement of diverse amoebae inferred from multigene analyses and assessment of clade stability within 'Amoebozoa' upon removal of varying rate classes of SSU-rDNA.
Yonas I. Tekle,Jessica R. Grant,O. Roger Anderson,Thomas A. Nerad,Jeffrey C. Cole,David J. Patterson,Laura A. Katz +6 more
TL;DR: Bayesian analysis of the concatenated data of the four genes sequenced, including diverse representatives of eukaryotes, indicates that all seven taxa group within the 'Amoebozoa' supergroup are valid and SSU-rDNA has a limited signal for deep relationships within the '.
Journal ArticleDOI
Molecular phylogeny of phyllopharyngean ciliates and their group I introns.
Oona Snoeyenbos-West,Jeffrey C. Cole,Anna Campbell,D. Wayne Coats,Laura A. Katz,Laura A. Katz +5 more
TL;DR: Analysis of small subunit ribosomal DNA sequences provides strong support for the monophyly of the ciliate class Phyllopharyngea, and exogenous budding appears to be basal to evaginative and endogenous budding.
Journal ArticleDOI
A multigene analysis of Corallomyxa tenera sp. nov. suggests its membership in a clade that includes Gromia, Haplosporidia and Foraminifera.
Yonas I. Tekle,Jessica R. Grant,Jeffrey C. Cole,Thomas A. Nerad,O. Roger Anderson,David J. Patterson,Laura A. Katz +6 more
TL;DR: A morphological description and multigene analysis are combined to assess the phylogenetic placement of a poorly known amoeboid taxon Corallomyxa within the eukaryotic tree of life and identify a novel stem in the predicted SSU-rDNA secondary structure that supports this relationship.
