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.

Extent of wild–to–crop interspecific introgression in grapevine (Vitis vinifera) as a consequence of resistance breeding and implications for the crop species definition

Horticulture Research, 2022
Over the past two centuries, introgression through repeated backcrossing has introduced disease resistance from wild grape species into the domesticated lineage Vitis vinifera subsp. sativa.

Genomic architecture and introgression shape a butterfly radiation

Science, 2018
Following gene flow in butterfly genomes The role of hybridization in evolution and species radiations has long been debated. In Heliconius butterflies, introgression was a major factor in their radiation, and the genetic variation it imparted into ...

Power of Bayesian and Heuristic Tests to Detect Cross-Species Introgression with Reference to Gene Flow in the Tamias quadrivittatus Group of North American Chipmunks

Systematic Biology, 2022
In the past two decades, genomic data have been widely used to detect historical gene flow between species in a variety of plants and animals. The Tamias quadrivittatus group of North America chipmunks, which originated through a series of rapid ...

Recovering signals of ghost archaic introgression in African populations

Science Advances, 2020
Multiple West African populations inherited genes from a population that diverged before modern humans and Neanderthals split. While introgression from Neanderthals and Denisovans has been documented in modern humans outside Africa, the contribution of ...

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.

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

Impact of Ghost Introgression on Coalescent-based Species Tree Inference and Estimation of Divergence Time

bioRxiv, 2022
The species studied in any evolutionary investigation generally constitute a very small proportion of all the species currently existing or that have gone extinct.

Genomic introgression through interspecific hybridization counteracts genetic bottleneck during soybean domestication

Genome Biology, 2019
Background Evidence of introgression, the transfer of genetic material, between crops and their wild relatives through spontaneous hybridization and subsequent backcrossing has been documented; however, the evolutionary patterns and consequences of ...

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.
