Indirect Identification of Horizontal Gene Transfer
David Schaller, Manuel Lafond, Peter F. Stadler +2
Several implicit methods to infer Horizontal Gene Transfer (HGT) focus on pairs of genes that have diverged only after the divergence of the two species in which the genes reside.…
Complete Edge-Colored Permutation Graphs
Tom Hartmann, Max Bannach, Martin Middendorf +3
We introduce the concept of complete edge-colored permutation graphs as complete graphs that are the edge-disjoint union of "classical" permutation graphs. We show that a graph $G=…
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…
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…
The Mathematics of Xenology: Di-cographs, Symbolic Ultrametrics, 2-structures and Tree-representable Systems of Binary Relations
Marc Hellmuth, Peter F. Stadler, Nicolas Wieseke
The concepts of orthology, paralogy, and xenology play a key role in molecular evolution. Orthology and paralogy distinguish whether a pair of genes originated by speciation or dup…
