GATC: a genetic algorithm for gene tree construction under the Duplication-Transfer-Loss model of evolution [PDF]

open access: goldBMC Genomics, 2018
Background Several methods have been developed for the accurate reconstruction of gene trees. Some of them use reconciliation with a species tree to correct, a posteriori, errors in gene trees inferred from multiple sequence alignments. Unfortunately the

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

open access: goldBMC 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

A Probabilistic Model for Gene Content Evolution with Duplication, Loss, and Horizontal Transfer [PDF]

open access: green, 2006
We introduce a Markov model for the evolution of a gene family along a phylogeny. The model includes parameters for the rates of horizontal gene transfer, gene duplication, and gene loss, in addition to branch lengths in the phylogeny. The likelihood for

The complete mitochondrial genome of Hyotissa sinensis (Bivalvia, Ostreoidea) indicates the genetic diversity within Gryphaeidae [PDF]

open access: yesBiodiversity Data Journal, 2023
Different from the true oyster (family Ostreidae), the molecular diversity of the gryphaeid oyster (family Gryphaeidae) has never been sufficiently investigated.

Improved Duplication-Transfer-Loss Reconciliation with Extinct and Unsampled Lineages

open access: yesAlgorithms, 2021
Duplication-Transfer-Loss (DTL) reconciliation is a widely used computational technique for understanding gene family evolution and inferring horizontal gene transfer (transfer for short) in microbes.

xenoGI 3: using the DTLOR model to reconstruct the evolution of gene families in clades of microbes

open access: yesBMC Bioinformatics, 2023
To understand genome evolution in a group of microbes, we need to know the timing of events such as duplications, deletions and horizontal transfers. A common approach is to perform a gene-tree / species-tree reconciliation.

The impact of gene duplication, insertion, deletion, lateral gene transfer and sequencing error on orthology inference: a simulation study. [PDF]

open access: yesPLoS ONE, 2013
The identification of orthologous genes, a prerequisite for numerous analyses in comparative and functional genomics, is commonly performed computationally from protein sequences. Several previous studies have compared the accuracy of orthology inference

Maximum parsimony reconciliation in the DTLOR model

open access: yesBMC Bioinformatics, 2021
Background Analyses of microbial evolution often use reconciliation methods. However, the standard duplication-transfer-loss (DTL) model does not account for the fact that species trees are often not fully sampled and thus, from the perspective of ...

Origin and evolution of the sodium -pumping NADH: ubiquinone oxidoreductase. [PDF]

open access: yesPLoS ONE, 2014
The sodium -pumping NADH: ubiquinone oxidoreductase (Na+-NQR) is the main ion pump and the primary entry site for electrons into the respiratory chain of many different types of pathogenic bacteria. This enzymatic complex creates a transmembrane gradient
