Williamsia faeni sp. nov., an actinomycete isolated from a hay meadow [PDF]

open access: yes, 2010
The taxonomic status of an actinomycete isolated from soil collected from a hay meadow was determined using a polyphasic approach. The strain, designated N1350T, had morphological and chemotaxonomic properties consistent with its classification in the ...

An efficient exact algorithm for computing all pairwise distances between reconciliations in the duplication-transfer-loss model

open access: yesBMC Bioinformatics, 2019
Background Maximum parsimony reconciliation in the duplication-transfer-loss model is widely used in studying the evolutionary histories of genes and species and in studying coevolution of parasites and their hosts and pairs of symbionts. While efficient

Inferring gene duplications, transfers and losses can be done in a discrete framework [PDF]

open access: yes, 2015
UMR AGAP : équipe GE2popInternational audienceIn the field of phylogenetics, the evolutionary history of a set of organisms is commonly depicted by a species tree – whose internal nodes represent speciation events – while the evolutionary history of a ...

Inferring Pareto-optimal reconciliations across multiple event costs under the duplication-loss-coalescence model

open access: yesBMC Bioinformatics, 2019
Background Reconciliation methods are widely used to explain incongruence between a gene tree and species tree. However, the common approach of inferring maximum parsimony reconciliations (MPRs) relies on user-defined costs for each type of event, which ...

DNA sequence evidence for speciation, paraphyly and a Mesozoic dispersal of cancellothyridid articulate brachiopods [PDF]

open access: yes, 2002
Because the classification of extant and fossil articulate brachiopods is based largely upon shell characters observable in fossils, it identifies morphotaxa whose biological status can, in practice, best be inferred from estimates of genetic divergence.

Joint amalgamation of most parsimonious reconciled gene trees. [PDF]

open access: yes, 2014
MOTIVATION Traditionally, gene phylogenies have been reconstructed solely on the basis of molecular sequences; this, however, often does not provide enough information to distinguish between statistically equivalent relationships.

Third-codon transversion rate-based _Nymphaea_ basal angiosperm phylogeny -- concordance with developmental evidence [PDF]

open access: yes, 2007
Flowering plants (angiosperms) appeared on Earth rather suddenly approximately 130 million years ago and underwent a massive expansion in the subsequent 10-12 million years.

Inferring Species Trees from Incongruent Multi-Copy Gene Trees Using the Robinson-Foulds Distance [PDF]

open access: yes, 2012
We present a new method for inferring species trees from multi-copy gene trees. Our method is based on a generalization of the Robinson-Foulds (RF) distance to multi-labeled trees (mul-trees), i.e., gene trees in which multiple leaves can have the same ...

The Most Parsimonious Reconciliation Problem in the Presence of Incomplete Lineage Sorting and Hybridization Is NP-Hard [PDF]

open access: yes, 2021
The maximum parsimony phylogenetic reconciliation problem seeks to explain incongruity between a gene phylogeny and a species phylogeny with respect to a set of evolutionary events.

Gene duplicability of core genes is highly consistent across all angiosperms [PDF]

open access: yes, 2016
Gene duplication is an important mechanism for adding to genomic novelty. Hence, which genes undergo duplication and are preserved following duplication is an important question. It has been observed that gene duplicability, or the ability of genes to be
