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

Current Biology, 2022
Biologists have forever sought to understand how species arise and persist. Historically, species that rarely interbreed, or are reproductively isolated, were considered the norm, while those with incomplete reproductive isolation were considered less common.

Prevalence and Adaptive Impact of Introgression
Annual Review of Genetics, 2021 Alleles that introgress between species can influence the evolutionary and ecological fate of species exposed to novel environments. Hybrid offspring of different species are often unfit, and yet it has long been argued that introgression can be a potent force in evolution, especially in plants. Over the last two decades, genomic data have increasingly

Introgression mapping in the grasses
Chromosome Research, 2007The unique properties of Lolium/Festuca hybrids and their derivatives provide an ideal system for intergeneric introgression. At IGER a focus on the Lolium perenne/Festuca pratensis system is being exploited to elucidate genome organization in the grasses, determination of the genetic control of target traits and the isolation of markers for marker ...

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

Parapatric genetic introgression and phenotypic assimilation: testing conditions for introgression between Hercules beetles (Dynastes, Dynastinae) [PDF]
Molecular Ecology, 2016 The prevalence and consequences of genetic introgression between species have been intensively debated. I used Hercules beetles as examples to test for conditions that may be associated with the occurrence of introgression.

Hybridization and Introgression
2019Spontaneous hybridization between taxa provides a source of genetic variation upon which selection may act. Though individual genetic variants are not new, the combinations of variants from diverse genomes found in hybrids are new (novel epistatic gene interactions), and hybrid populations may, and often do, contain more genetic diversity than their ...

Statistical Analysis of Introgression
Biometrics, 1966SUMMARY Measurements of introgression may be made on scales established by principal components, canonical correlation vectors, discriminant functions, hybrid indices, and a proposed distance analysis. The distance analysis developed is the most sensitive scale used.

Hybridization and Introgression
2001The study of natural hybridization using secondary metabolites, particularly flavonoids, attracted a good deal of attention following the pioneering work of Ralph Alston and his colleagues at the University of Texas. Sorting out the complex patterns in populations of hybridizing Baptisia species by morphological means alone was extremely difficult ...

THE ANNOTATION OF INTROGRESSANTS
TAXON, 1958The recent paper by Hui-Lin Li (Taxon 6: 216-218. 1957) brought up a problem about which a number of us dealing with introgression have been wondering, namely what is the best method for designating backcrosses and members of hybrid swarms. In a paper dealing with introgression in Aesculus (Rhodora 59: 185-203. 1957) I used a different formula from the
