Gene tree species tree reconciliation with gene conversion
Gene tree/species tree reconciliation is a recent decisive progress in phylogenetic methods, accounting for the possible differences between gene histories and species histories. Reconciliation consists in explaining these differences by gene-scale events such as duplication, loss, transfer, which translates mathematically into a mapping between gene tree nodes and species tree nodes or branche...
متن کاملDistributions of topological tree metrics between a species tree and a gene tree
In order to conduct a statistical analysis on a given set of phylogenetic gene trees, we often use a distance measure between two trees. In a statistical distance-based method to analyze discordance between gene trees, it is a key to decide “biological meaningful” and “statistically well-distributed” distance between trees. Thus, in this paper, we study the distributions of the three tree dista...
متن کاملReconciling Gene Trees to a Species Tree
In this paper we deal with the general problem of recombining the information from evolutionary trees representing the relationships between distinct gene families. First we solve a problem from [8] regarding the construction of a minimum reconciled tree by giving an efficient algorithm. Then we show that the exemplar problem, arising from the exemplar analysis of multigene genomes [2], is NP-h...
متن کاملBUCKy: Gene tree/species tree reconciliation with Bayesian concordance analysis
MOTIVATION BUCKy is a C++ program that implements Bayesian concordance analysis. The method uses a non-parametric clustering of genes with compatible trees, and reconstructs the primary concordance tree from clades supported by the largest proportions of genes. A population tree with branch lengths in coalescent units is estimated from quartet concordance factors. AVAILABILITY BUCKy is open s...
متن کاملecceTERA: comprehensive gene tree-species tree reconciliation using parsimony
UNLABELLED : A gene tree-species tree reconciliation explains the evolution of a gene tree within the species tree given a model of gene-family evolution. We describe ecceTERA, a program that implements a generic parsimony reconciliation algorithm, which accounts for gene duplication, loss and transfer (DTL) as well as speciation, involving sampled and unsampled lineages, within undated, fully ...
