The Spatial Signature of Introgression After a Biological Invasion With Hybridization

Frontiers 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.

Key Roles of De-Domestication and Novel Mutation in Origin and Diversification of Global Weedy Rice

Biology, 2021
Agricultural weeds pose great challenges to sustainable crop production, owing to their complex origins and abundant genetic diversity. Weedy rice (WD) infests rice fields worldwide causing tremendous losses of rice yield/quality.

Recombination rate variation shapes barriers to introgression across butterfly genomes

bioRxiv, 2018
Hybridisation and introgression can dramatically alter the relationships among groups of species, leading to phylogenetic discordance across the genome and between populations.

Phylogenetic systematics of Juncaceae

American Journal of Botany, EarlyView.
Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within it. In 2022, a new classification was proposed, based on phylogenies built from one nuclear and three plastid regions ...

Combined detection and introgression of QTL in outbred populations

Genetics Selection Evolution, 2010
Background Detecting a QTL is only the first step in genetic improvement programs. When a QTL with desirable characteristics is found, e.g. in a wild or unimproved population, it may be interesting to introgress the detected QTL into the commercial ...

Detecting cryptic ghost lineage introgression in four‐taxon genomic datasets

Applications in Plant Sciences, EarlyView.
Abstract Premise Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four‐taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression from genomic data, which have played an important role in ...

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

Rice 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

Frequent intra- and inter-species introgression shapes the landscape of genetic variation in bread wheat

Genome Biology, 2019
Bread wheat is one of the most important and broadly studied crops. However, due to the complexity of its genome and incomplete genome collection of wild populations, the bread wheat genome landscape and domestication history remain elusive.

Extensive introgression and mosaic genomes of Mediterranean endemic lizards

Nature Communications, 2021
The Mediterranean basin is a hotspot of biodiversity, fuelled by climatic oscillation and geological change over the past 20 million years. Wall lizards of the genus Podarcis are among the most abundant, diverse, and conspicuous Mediterranean fauna. Here,

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,
