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 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.

Phylogenomic approaches to detecting and characterizing introgression [PDF]
Genetics, 2021 AbstractPhylogenomics has revealed the remarkable frequency with which introgression occurs across the tree of life. These discoveries have been enabled by the rapid growth of methods designed to detect and characterize introgression from whole-genome sequencing data.

Adaptive introgression: a plant perspective [PDF]
Biology Letters, 2018 Introgression is emerging as an important source of novel genetic variation, alongside standing variation and mutation. It is adaptive when such introgressed alleles are maintained by natural selection. Recently, there has been an explosion in the number of studies on adaptive introgression.

Effects of asymmetric nuclear introgression, introgressive mitochondrial sweep, and purifying selection on phylogenetic reconstruction and divergence estimates in the Pacific clade of Locustella warblers. [PDF]
PLoS ONE, 2015 When isolated but reproductively compatible populations expand geographically and meet, simulations predict asymmetric introgression of neutral loci from a local to invading taxon. Genetic introgression may affect phylogenetic reconstruction by obscuring

Benefit of Introgression Depends on Level of Genetic Trait Variation in Cereal Breeding Programmes
Frontiers in Plant Science, 2022 We investigated the benefit from introgression of external lines into a cereal breeding programme and strategies that accelerated introgression of the favourable alleles while minimising linkage drag using stochastic computer simulation.

Detecting adaptive introgression in human evolution using convolutional neural networks
eLife, 2021 Studies in a variety of species have shown evidence for positively selected variants introduced into a population via introgression from another, distantly related population—a process known as adaptive introgression.

VolcanoFinder: genomic scans for adaptive introgression [PDF]
PLOS Genetics, 2019 AbstractRecent research shows that introgression between closely-related species is an important source of adaptive alleles for a wide range of taxa. Typically, detection of adaptive introgression from genomic data relies on comparative analyses that require sequence data from both the recipient and the donor species.
