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

Sex chromosome turnover in hybridizing stickleback lineages
Evolution 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.

Natural hybridization generates mammalian lineage with species characteristics [PDF]
Proceedings 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.

DNA hybridization evidence for the principal lineages of hummingbirds (Aves:Trochilidae) [PDF]
Molecular Biology and Evolution, 1997 The spectacular evolutionary radiation of hummingbirds (Trochilidae) has served as a model system for many biological studies. To begin to provide a historical context for these investigations, we generated a complete matrix of DNA hybridization distances among 26 hummingbirds and an outgroup swift (Chaetura pelagica) to determine the principal ...

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

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

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

Parsimonious Inference of Hybridization in the Presence of Incomplete Lineage Sorting [PDF]
Systematic Biology, 2013 Hybridization plays an important evolutionary role in several groups of organisms. A phylogenetic approach to detect hybridization entails sequencing multiple loci across the genomes of a group of species of interest, reconstructing their gene trees, and taking their differences as indicators of hybridization. However, methods that follow this approach

Global Analysis of Dynamic Epigenetic Marking and Transcriptional Regulation Underlying T-Cell Lineage Commitment [PDF]
, 2012 T-cell lineage specification and commitment success depends on precise temporal induction of T-lineage specific genes, as well as repression of lineage-inappropriate programs. After entry into the thymus, T-cell progenitors still retain inherited lineage
