Exploring the genetic variation of wheat-Triticum timopheevii introgression lines for flowering morphology traits for hybrid wheat use [PDF]

Frontiers in Plant Science
IntroductionThe autogamous nature of wheat presents a significant challenge for hybrid wheat breeding, which relies on cross-pollination. To facilitate hybrid wheat production, it is essential to modify the floral morphology of wheat to promote ...

Introgression impacts the evolution of bacteria, but species borders are rarely fuzzy [PDF]

Nature Communications
Most bacteria engage in gene flow through homologous recombination, and this mechanism may play a crucial role in maintaining species cohesiveness, much like sexual reproduction does in eukaryotes. However, introgression has been reported in bacteria and

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.

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.

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.

When One’s Not Enough: Colony Pool-Seq Outperforms Individual-Based Methods for Assessing Introgression in Apis mellifera mellifera

Insects, 2023
The human management of honey bees (Apis mellifera) has resulted in the widespread introduction of subspecies outside of their native ranges. One well known example of this is Apis mellifera mellifera, native to Northern Europe, which has now been ...

A need for standardized reporting of introgression: Insights from studies across eukaryotes

Evolution Letters, 2022
With the rise of affordable next‐generation sequencing technology, introgression—or the exchange of genetic materials between taxa—has become widely perceived to be a ubiquitous phenomenon in nature.

The effects of introgression across thousands of quantitative traits revealed by gene expression in wild tomatoes

PLoS Genetics, 2021
It is now understood that introgression can serve as powerful evolutionary force, providing genetic variation that can shape the course of trait evolution.

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

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
