A hybrid sub-lineage of Listeria monocytogenes comprising hypervirulent isolates [PDF]

open access: yesNature Communications, 2019
Listeria monocytogenes isolates are highly heterogeneous and exhibit different levels of virulence. Here, the authors identify hypervirulent isolates that represent a hybrid sub-lineage of the major lineage II harbouring virulence factors from Listeria ...

Revealing the Detailed Lineage of Script Outputs Using Hybrid Provenance [PDF]

open access: yesInternational Journal of Digital Curation, 2018
We illustrate how combining retrospective and prospectiveprovenance can yield scientifically meaningful hybrid provenancerepresentations of the computational histories of data produced during a script run.

Ancient hybridization underlies tuberization and radiation of the potato lineage

open access: yesCell
Interspecific hybridization may trigger species radiation by creating allele combinations and traits. Cultivated potato and its 107 wild relatives from the Petota lineage all share the distinctive trait of underground tubers, but the underlying mechanisms for tuberization and its relationship to extensive species diversification remain unclear.

Sex chromosome turnover in hybridizing stickleback lineages

open access: yesEvolution Letters, 2023
Abstract Recent discoveries of sex chromosome diversity across the tree of life have challenged the canonical model of conserved sex chromosome evolution and evoked new theories on labile sex chromosomes that maintain less differentiation and undergo frequent turnover.

Disentangling Population History and Character Evolution among Hybridizing Lineages [PDF]

open access: yesMolecular Biology and Evolution, 2020
AbstractUnderstanding the origin and maintenance of adaptive phenotypic novelty is a central goal of evolutionary biology. However, both hybridization and incomplete lineage sorting can lead to genealogical discordance between the regions of the genome underlying adaptive traits and the remainder of the genome, decoupling inferences about character ...

Natural hybridization generates mammalian lineage with species characteristics [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Most diploid species arise from single-species ancestors. Hybrid origins of new species are uncommon (except among polyploids) and are documented infrequently in animals. Examples of natural hybridization leading to speciation in mammals are exceedingly rare.

Using supernetworks to distinguish hybridization from lineage-sorting [PDF]

open access: yesBMC Evolutionary Biology, 2008
A simple and widely used approach for detecting hybridization in phylogenies is to reconstruct gene trees from independent gene loci, and to look for gene tree incongruence. However, this approach may be confounded by factors such as poor taxon-sampling and/or incomplete lineage-sorting.Using coalescent simulations, we investigated the potential of ...

Repeated Reticulate Evolution in North American Papilio machaon Group Swallowtail Butterflies. [PDF]

open access: yesPLoS ONE, 2015
Hybridization between distinct populations or species is increasingly recognized as an important process for generating biodiversity. However, the interaction between hybridization and speciation is complex, and the diverse evolutionary outcomes of ...

First cytogenetic register of an allopolyploid lineage of the genus Aeschynomene (Leguminosae, Papilionoideae) native to Mexico

open access: yesCaryologia, 2021
A conventional cytogenetics analysis revealed for first time an allopolyploid lineage of the genus Aeschynomene in Mexico. The hybrid condition is confirmed after all the prometaphase and metaphase nuclei of the hybrids exhibited only one pair of SAT ...

Beyond clines: lineages and haplotype blocks in hybrid zones [PDF]

open access: yesMolecular Ecology, 2016
Abstract Hybrid zones formed between recently diverged populations offer an opportunity to study the mechanisms underlying reproductive isolation and the process of speciation. Here, we use a combination of analytical theory and explicit forward simulations to describe how selection against hybrid genotypes ...
