Phylogenomics with Paralogs
Marc Hellmuth, Nicolas Wieseke, Marcus Lechner +3
Phylogenomics heavily relies on well-curated sequence data sets that consist, for each gene, exclusively of 1:1-orthologous. Paralogs are treated as a dangerous nuisance that has t…
Reconstructing Gene Trees From Fitch's Xenology Relation
Manuela Geiß, John Anders, Peter F. Stadler +2
Two genes are xenologs in the sense of Fitch if they are separated by at least one horizontal gene transfer event. Horizonal gene transfer is asymmetric in the sense that the trans…
Partial Homology Relations - Satisfiability in terms of Di-Cographs
Nikolai Nøjgaard, Nadia El-Mabrouk, Daniel Merkle +2
Directed cographs (di-cographs) play a crucial role in the reconstruction of evolutionary histories of genes based on homology relations which are binary relations between genes. A…
From event labeled gene trees to species trees
Maribel Hernandez-Rosales, Marc Hellmuth, Nicolas Wieseke +3
Background: Tree reconciliation problems have long been studied in phylogenetics. A particular variant of the reconciliation problem for a gene tree T and a species tree S assumes…
Forbidden Time Travel: Characterization of Time-Consistent Tree Reconciliation Maps
Nikolai Nøjgaard, Manuela Geiß, Peter F. Stadler +3
In the absence of horizontal gene transfer it is possible to reconstruct the history of gene families from empirically determined orthology relations, which are equivalent to event…
