Recombination rate variation shapes barriers to introgression across butterfly genomes

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

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

open access: yesAdvanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

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

open access: yesRice 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

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

open access: yesBiology, 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.

Interaction of Introgression From \u3ci\u3ePapilio Glaucus Canadensis\u3c/i\u3e and Diapause in Producing Spring Form Eastern Tiger Swallowtail Butterflies, \u3ci\u3eP. Glaucus\u3c/i\u3e (Lepidoptera: Palilionidae) [PDF]

open access: yes, 2017
The small early spring form of the eastern tiger swallowtail butterfly, Papilio glaucus has been described from Massachusetts and Illinois in the north, southward all the way into North Carolina.

Primate phylogenomics uncovers multiple rapid radiations and ancient interspecific introgression

open access: yesbioRxiv, 2020
Our understanding of the evolutionary history of primates is undergoing continual revision due to ongoing genome sequencing efforts. Bolstered by growing fossil evidence, these data have led to increased acceptance of once controversial hypotheses ...

Extensive introgression and mosaic genomes of Mediterranean endemic lizards

open access: yesNature 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,

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

open access: yesAdvanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Rare coral under the genomic microscope: timing and relationships among Hawaiian Montipora [PDF]

open access: yes, 2019
Background Evolutionary patterns of scleractinian (stony) corals are difficult to infer given the existence of few diagnostic characters and pervasive phenotypic plasticity.

Correlation and the Structure of Introgressive Populations [PDF]

open access: yesEvolution, 1966
Anderson (1949) has reviewed in detail the currently available techniques for the study of introgression. He has indicated (Anderson 1954, 1956, 1957) that the use of metroglyphs (the "pictures" used in pictorial scatter diagrams) is the most efficient means of analyzing suspected examples of introgression.
