An HMM-based comparative genomic framework for detecting introgression in eukaryotes. [PDF]

PLoS Computational Biology, 2014
One outcome of interspecific hybridization and subsequent effects of evolutionary forces is introgression, which is the integration of genetic material from one species into the genome of an individual in another species.

The recombination landscape of introgression in yeast. [PDF]

PLoS Genetics
Meiotic recombination is an evolutionary force that acts by breaking up genomic linkage, increasing the efficacy of selection. Recombination is initiated with a double-strand break which is resolved via a crossover, which involves the reciprocal exchange

The Genomic Signature of Crop-Wild Introgression in Maize [PDF]

PLoS Genetics 2013 9(5): e1003477, 2012
The evolutionary significance of hybridization and subsequent introgression has long been appreciated, but evaluation of the genome-wide effects of these phenomena has only recently become possible. Crop-wild study systems represent ideal opportunities to examine evolution through hybridization.

Hominin evolution was caused by introgression from Gorilla [PDF]

Natural Science Vol.10 No.09(2018), Article ID:87215, 9 pages, 2018
The discovery of Paranthropus deyiremeda in 3.3-3.5 million year old fossil sites in Afar, together with 30% of the gorilla genome showing lineage sorting between humans and chimpanzees, and a NUMT ("nuclear mitochondrial DNA segment") on chromosome 5 that is shared by both gorillas, humans and chimpanzees, and shown to have diverged at the time of the

The dynamics of introgression across an avian radiation [PDF]

Evolution Letters, 2021
Hybridization and resulting introgression can play both a destructive and a creative role in the evolution of diversity. Thus, characterizing when and where introgression is most likely to occur can help us understand the causes of diversification ...

Introgression in interspecific hybrids of lily [PDF]

Acta Horticulturae, 2002
In order to introduce new desirable characters into the cultivar assortment of lily a range of interspecific crossing barriers has to be overcome. By using various pollination and embryo rescue techniques pre- and postfertilization barriers were overcome

Population Genomics Unravels the Characteristic Relationship between Introgression and Geographical Distribution in Upland Cotton

Agronomy, 2023
Introgression is an important driver of new genetic variation that increases species and genetic diversity. However, the relationship between introgression and geographic distribution of upland cotton is still unclear.

Different Roles of Introgression on the Demographic Change in Two Snakebark Maples, Acer caudatifolium and A. morrisonense, with Contrasted Postglacial Expansion Routes

Plants, 2022
Hybridization frequently occurs in plant species. With repeated backcross, the introgression may influence evolutionary trajectories through the entry of foreign genes.

Genetic introgression between different groups reveals the differential process of Asian cultivated rice

Scientific Reports, 2022
The Asian cultivated rice consists of two major subspecies: indica and japonica. There are already many reports about the existence of genetic introgression between the two subspecies.

Adaptation by introgression [PDF]

Journal of Biology, 2009
Both selective and random processes can affect the outcome of natural hybridization. A recent analysis in BMC Evolutionary Biology of natural hybridization between an introduced and a native salamander reveals the mosaic nature of introgression, which is probably caused by a combination of selection and demography.
