Maximum parsimony reconciliation in the DTLOR model [PDF]

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 ...

Hierarchical clustering of maximum parsimony reconciliations

open access: yesBMC Bioinformatics, 2019
Background Maximum parsimony reconciliation in the duplication-transfer-loss model is a widely-used method for analyzing the evolutionary histories of pairs of entities such as hosts and parasites, symbiont species, and species and genes. While efficient

Phylogenetic analysis of seven WRKY genes across the palm subtribe Attaleinae (Arecaceae) [corrected] identifies Syagrus as sister group of the coconut. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:The Cocoseae is one of 13 tribes of Arecaceae subfam. Arecoideae, and contains a number of palms with significant economic importance, including the monotypic and pantropical Cocos nucifera L., the coconut, the origins of which have been one ...

Feasibility of nuclear ribosomal region ITS1 over ITS2 in barcoding taxonomically challenging genera of subtribe Cassiinae (Fabaceae) [PDF]

open access: yesPeerJ, 2016
Premise of the Study The internal transcribed spacer (ITS) region is situated between 18S and 26S in a polycistronic rRNA precursor transcript. It had been proved to be the most commonly sequenced region across plant species to resolve phylogenetic ...

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 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 ...

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 ...
