A Framework for Representing Reticulate Evolution [PDF]

open access: yesAnnals of Combinatorics, 2005
In biology it is a very important task representing the evolution of the living world. Generally rooted trees are used to display the evolutionary relations. It is well known, however, that the real-world evolution is ``reticulate'' (= non-tree like) as a consequence of ``hybridizations'' and ``horizontal gene transfers''.

Reticulate Evolution of the Rye Genome [PDF]

open access: yesThe Plant Cell, 2013
Rye (Secale cereale) is closely related to wheat (Triticum aestivum) and barley (Hordeum vulgare). Due to its large genome (~8 Gb) and its regional importance, genome analysis of rye has lagged behind other cereals. Here, we established a virtual linear gene order model (genome zipper) comprising 22,426 or 72% of the detected set of 31,008 rye genes ...

Nightmare or delight: taxonomic circumscription meets reticulate evolution in the phylogenomic era

open access: yesbioRxiv, 2023
Phylogenetic studies in the phylogenomics era have demonstrated that reticulate evolution greatly impedes the accuracy of phylogenetic inference, and consequently can obscure taxonomic treatments.

Phylogeny reconstruction and hybrid analysis of populus (Salicaceae) based on nucleotide sequences of multiple single-copy nuclear genes and plastid fragments. [PDF]

open access: yesPLoS ONE, 2014
Populus (Salicaceae) is one of the most economically and ecologically important genera of forest trees. The complex reticulate evolution and lack of highly variable orthologous single-copy DNA markers have posed difficulties in resolving the phylogeny of

A Molecular Phylogeny of Stylodipus (Dipodidae, Mammalia): A Small Genus with a Complex History

open access: yesDiversity, 2023
A range-wide phylogenetic/phylogeographic study of the three-toed jerboas of the genus Stylodipus is conducted using the mitochondrial cytb gene and fragments of several nuclear genes. The genus has been believed to include three species: S.

Reticulate evolution is favored in influenza niche switching. [PDF]

open access: yesProc Natl Acad Sci U S A, 2016
Significance Are the processes that result in the exchange of genes between microbes quantitatively advantageous for those microbes when switching between ecological niches? To address this question, we consider the influenza A virus as a model microbe, with its ability to infect multiple host species (ecological niches) and undergo ...

Taxonomy of the Crematogaster degeeri-species-assemblage in the Malagasy region (Hymenoptera: Formicidae) [PDF]

open access: yes, 2013
We revise the species-level taxonomy of the Crematogaster (Crematogaster) degeerispecies-assemblage, a group of related ants occuring in Madagascar and the wider Malagasy region, and further provide an identification key to all species-groups of the ...

QS-Net: Reconstructing Phylogenetic Networks Based on Quartet and Sextet

open access: yesFrontiers in Genetics, 2019
Phylogenetic networks are used to estimate evolutionary relationships among biological entities or taxa involving reticulate events such as horizontal gene transfer, hybridization, recombination, and reassortment.

Which phylogenetic networks are merely trees with additional arcs? [PDF]

open access: yes, 2015
A binary phylogenetic network may or may not be obtainable from a tree by the addition of directed edges (arcs) between tree arcs. Here, we establish a precise and easily tested criterion (based on `2-SAT') that efficiently determines whether or not any ...

Reconstructible phylogenetic networks: do not distinguish the indistinguishable. [PDF]

open access: yesPLoS Computational Biology, 2015
Phylogenetic networks represent the evolution of organisms that have undergone reticulate events, such as recombination, hybrid speciation or lateral gene transfer. An important way to interpret a phylogenetic network is in terms of the trees it displays,
