Divergence-Based Introgression Polarization [PDF]

Genome Biology and Evolution, 2019
AbstractIntrogressive hybridization results in the transfer of genetic material between species, often with fitness implications for the recipient species. The development of statistical methods for detecting the signatures of historical introgression in whole-genome data has been a major area of focus. Although existing techniques are able to identify

Dynamics of mtDNA introgression during species range expansion. Insights from an experimental longitudinal study [PDF]

, 2016
Introgressive hybridization represents one of the long-lasting debated genetic consequences of species range expansion. Mitochondrial DNA has been shown to heavily introgress between interbreeding animal species that meet in new sympatric areas and ...

Assessing biological factors affecting postspeciation introgression

Evolution Letters, 2020
An increasing number of phylogenomic studies have documented a clear “footprint” of postspeciation introgression among closely related species. Nonetheless, systematic genome‐wide studies of factors that determine the likelihood of introgression remain ...

Characterization of introgression from the teosinte Zea mays ssp. mexicana to Mexican highland maize [PDF]

PeerJ, 2019
Background The spread of maize cultivation to the highlands of central Mexico was accompanied by substantial introgression from the endemic wild teosinte Zea mays ssp.

The genomic impact of historical hybridization with massive mitochondrial DNA introgression

Genome Biology, 2018
Background The extent to which selection determines interspecific patterns of genetic exchange enlightens the role of adaptation in evolution and speciation.

Detection of T. urartu Introgressions in Wheat and Development of a Panel of Interspecific Introgression Lines [PDF]

Frontiers in Plant Science, 2018
Tritcum urartu (2n = 2x = 14, AuAu), the A genome donor of wheat, is an important source for new genetic variation for wheat improvement due to its high photosynthetic rate and disease resistance. By facilitating the generation of genome-wide introgressions leading to a variety of different wheat-T. urartu translocation lines, T.

Alien introgression in rice

The Nucleus, 1997
Rice (Oryza sativa L.) productivity is affected by several biotic and abiotic stresses. The genetic variability for some of these stresses is limited in the cultivated rice germplasm. Moreover, changes in insect biotypes and disease races are a continuing threat to increased rice production. There is thus an urgent need to broaden the rice gene pool by

The Genetic Cost of Neanderthal Introgression [PDF]

Genetics, 2015
AbstractApproximately 2–4% of genetic material in human populations outside Africa is derived from Neanderthals who interbred with anatomically modern humans. Recent studies have shown that this Neanderthal DNA is depleted around functional genomic regions; this has been suggested to be a consequence of harmful epistatic interactions between human and ...

A three-sample test for introgression [PDF]

Molecular Biology and Evolution, 2019
AbstractMany methods exist for detecting introgression between non-sister species, but the most commonly used require either a single sequence from four or more taxa or multiple sequences from each of three taxa. Here we present a test for introgression that uses only a single sequence from three taxa.
