Ghost introgression facilitates genomic divergence of a sympatric cryptic lineage in Cycas revoluta

Ecology and Evolution, 2023
A cryptic lineage is a genetically diverged but morphologically unrecognized variant of a known species. Clarifying cryptic lineage evolution is essential for quantifying species diversity. In sympatric cryptic lineage divergence compared with allopatric

Extensive Genome-Wide Phylogenetic Discordance Is Due to Incomplete Lineage Sorting and Not Ongoing Introgression in a Rapidly Radiated Bryophyte Genus

Molecular biology and evolution, 2021
The relative importance of introgression for diversification has long been a highly disputed topic in speciation research and remains an open question despite the great attention it has received over the past decade. Gene flow leaves traces in the genome

Large-scale introgression shapes the evolution of the mating-type chromosomes of the filamentous ascomycete Neurospora tetrasperma. [PDF]

PLoS Genetics, 2012
The significance of introgression as an evolutionary force shaping natural populations is well established, especially in animal and plant systems. However, the abundance and size of introgression tracts, and to what degree interspecific gene flow is the

Demographic History and Natural Selection Shape Patterns of Deleterious Mutation Load and Barriers to Introgression across Populus Genome

Molecular biology and evolution, 2022
Hybridization and resulting introgression are important processes shaping the tree of life and appear to be far more common than previously thought.

Divergence-Based Introgression Polarization [PDF]

Genome Biology and Evolution, 2019
Abstract Introgressive hybridization results in the transfer of genetic material between species, often with fitness implications for the recipient species. The development of statistical methods for detecting the signatures of historical introgression in whole-genome data has been a major area of focus.

Crop–Weed Introgression Plays Critical Roles in Genetic Differentiation and Diversity of Weedy Rice: A Case Study of Human-Influenced Weed Evolution

Biology, 2023
As an important driving force, introgression plays an essential role in shaping the evolution of plant species. However, knowledge concerning how introgression affects plant evolution in agroecosystems with strong human influences is still limited.

Genomic Patterns of Introgression in Interspecific Populations Created by Crossing Wheat with Its Wild Relative

G3: Genes, Genomes, Genetics, 2020
Introgression from wild relatives is a valuable source of novel allelic diversity for breeding. We investigated the genomic patterns of introgression from Aegilops tauschii, the diploid ancestor of the wheat D genome, into winter wheat (Triticum aestivum)

An adaptive teosinte mexicana introgression modulates phosphatidylcholine levels and is associated with maize flowering time

Proceedings of the National Academy of Sciences of the United States of America, 2022
Significance Despite more than a century of genetic research, our understanding of the genetic basis of the astounding capacity of maize to adapt to new environments is in its infancy.

Widespread introgression across a phylogeny of 155 Drosophila genomes

bioRxiv, 2020
Genome-scale sequence data have invigorated the study of hybridization and introgression, particularly in animals. However, outside of a few notable cases, we lack systematic tests for introgression at a larger phylogenetic scale across entire clades ...

Ghost Lineages Highly Influence the Interpretation of Introgression Tests

bioRxiv, 2021
Most species are extinct; those that are not are often unknown. Sequenced and sampled species are often a minority of known ones. Past evolutionary events involving horizontal gene flow, such as horizontal gene transfer, hybridization, introgression and ...
