Unifying Parsimonious Tree Reconciliation

open access: yes, 2013
Evolution is a process that is influenced by various environmental factors, e.g. the interactions between different species, genes, and biogeographical properties.

Actinopolyspora saharensis sp. nov., a novel halophilic actinomycete isolated from a Saharan soil of Algeria [PDF]

open access: yes, 2012
A novel halophilic actinomycete, strain H32T,was isolated froma Saharan soil sample collected in El-Oued province, south Algeria. The isolate was characterized by means of polyphasic taxonomy. Optimal growth was determined to occur at 28–32°C, pH 6.0–7.0

Inferring duplications, losses, transfers and incomplete lineage sorting with nonbinary species trees

open access: yesBioinform., 2012
Motivation: Gene duplication (D), transfer (T), loss (L) and incomplete lineage sorting (I) are crucial to the evolution of gene families and the emergence of novel functions. The history of these events can be inferred via comparison of gene and species

Halorubrum chaoviator sp. nov., a haloarchaeon isolated from sea salt in Baja California, Mexico, Western Australia and Naxos, Greece [PDF]

open access: yes, 2009
hree halophilic isolates, strains Halo-G*T, AUS-1 and Naxos II, were compared. Halo-G* was isolated from an evaporitic salt crystal from Baja California, Mexico, whereas AUS-1 and Naxos II were isolated from salt pools in Western Australia and the Greek ...

Inference of Ancient Whole-Genome Duplications and the Evolution of Gene Duplication and Loss Rates.

open access: yesMolecular biology and evolution, 2019
Gene tree-species tree reconciliation methods have been employed for studying ancient whole-genome duplication (WGD) events across the eukaryotic tree of life.

Genome-scale phylogenetic analysis finds extensive gene transfer among Fungi [PDF]

open access: yes, 2015
Although the role of lateral gene transfer is well recognized in the evolution of bacteria, it is generally assumed that it has had less influence among eukaryotes.

Maximum Parsimony Inference of Phylogenetic Networks in the Presence of Polyploid Complexes

open access: yesbioRxiv, 2020
Phylogenetic networks provide a powerful framework for modeling and analyzing reticulate evolutionary histories. While polyploidy has been shown to be prevalent not only in plants but also in other groups of eukaryotic species, most work done thus far on

Maximum likelihood models and algorithms for gene tree evolution with duplications and losses

open access: yesBMC Bioinformatics, 2011
Background The abundance of new genomic data provides the opportunity to map the location of gene duplication and loss events on a species phylogeny. The first methods for mapping gene duplications and losses were based on a parsimony criterion, finding ...

Multiple Optimal Reconciliations Under the Duplication-Loss-Coalescence Model

open access: yesIEEE/ACM Transactions on Computational Biology & Bioinformatics, 2019
Gene trees can differ from species trees due to a variety of biological phenomena, the most prevalent being gene duplication, horizontal gene transfer, gene loss, and coalescence.

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
