Detecting adaptive introgression in human evolution using convolutional neural networks

open access: yeseLife, 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.

Genomic introgression through interspecific hybridization counteracts genetic bottleneck during soybean domestication

open access: yesGenome 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 ...

Extensive introgression among strongylocentrotid sea urchins revealed by phylogenomics

open access: yesEcology and Evolution, 2023
Gametic isolation is thought to play an important role in the evolution of reproductive isolation in broadcast‐spawning marine invertebrates. However, it is unclear whether gametic isolation commonly evolves early in the speciation process or only ...

Selective sorting of ancestral introgression in maize and teosinte along an elevational cline.

open access: yesPLoS Genetics, 2021
While often deleterious, hybridization can also be a key source of genetic variation and pre-adapted haplotypes, enabling rapid evolution and niche expansion.

Extensive microsatellite variation in rice induced by introgression from wild rice (Zizania latifolia Griseb.).

open access: yesPLoS ONE, 2013
BackgroundIt is widely accepted that interspecific hybridization may induce genomic instability in the resultant hybrids. However, few studies have been performed on the genomic analysis of homoploid hybrids and introgression lines.

The role of recombination landscape in species hybridisation and speciation

open access: yesFrontiers in Plant Science, 2023
It is now well recognised that closely related species can hybridize and exchange genetic material, which may promote or oppose adaptation and speciation.

Development and Identification of Novel Rice Blast Resistant Sources and Their Characterization Using Molecular Markers

open access: yesRice Science, 2015
To develop and characterize introgression lines for leaf and neck blast resistance, 326 introgression lines were developed using various accessions of six different AA genome wild species in the genetic background of elite Indian varieties like PR114 and

Deleterious mutation load in the admixed mice population

open access: yesFrontiers in Ecology and Evolution, 2023
Deleterious mutation loads are known to correlate negatively with effective population size (Ne). Due to this reason, previous studies observed a higher proportion of harmful mutations in small populations than that in large populations.

The Spatial Signature of Introgression After a Biological Invasion With Hybridization

open access: yesFrontiers in Ecology and Evolution, 2020
The accumulation of genome-wide molecular data has emphasized the important role of hybridization in the evolution of many organisms, which may carry introgressed genomic segments resulting from past admixture events with other taxa.

The relevance of gene flow with wild relatives in understanding the domestication process [PDF]

open access: yesRoyal Society Open Science, 2020
The widespread use of genomic tools has allowed for a deeper understanding of the genetics and the evolutionary dynamics of domestication. Recent studies have suggested that multiple domestications and introgression are more common than previously ...
