This study models how polyploidy facilitates gene flow between diploid species by acting as a bridge, showing that increased recombination can enhance allele sorting and overcome species barriers.

The paper finds that genetic exchange is more frequent between animal species than plant species at the same level of genetic divergence, suggesting faster establishment of species barriers in plants.

The paper develops a mechanistic model to explore how metabolic efficiency influences polyploid invasion and coexistence with diploid ancestors in plants.

This study shows that duplicated gene regulatory networks increase signal output variation, enabling polyploid populations to better survive environmental upheaval, but may be maladaptive in stable environments.

The paper examines how whole-genome duplications (WGDs) and small-scale duplications (SSD) influence gene regulatory networks (GRNs) in angiosperms by analyzing network motifs and their association with functional categories.

This study presents chromosome-level genome assemblies of seagrass species and identifies ancient and recent genome duplication events linked to adaptation to marine environments.

The paper reconstructs the colonization history of eelgrass using genomic data, showing trans-Pacific currents drove its spread and Atlantic populations arrived more recently with lower genetic diversity.

The paper reanalyzes ancient whole-genome duplication events in leptosporangiate ferns using phylogenetic methods and substitution rate corrections, identifying four WGDs and highlighting methodological uncertainties.

This study investigates the genetic basis of herbicide resistance in blackgrass, finding that target-site resistance primarily arises from standing genetic variation rather than de novo mutations.

The paper introduces a two-type branching process model to better capture gene family evolution dynamics and applies it to Drosophila, yeasts, and primates data.

This study shows that clonal seagrass shoots have DNA methylation variation linked to photosynthetic performance and heat stress resilience, suggesting epigenetic variation complements genetic diversity in stress adaptation.

The paper analyzes a mid-15th century Bantu-speaker faecal specimen to understand the ancestral sub-Saharan African intestinal microbiome and its response to dietary and environmental changes.

This study develops a Bayesian method to detect ancient whole-genome duplications in phylogenies, overcoming limitations of existing approaches by allowing flexible model assumptions and discovering WGDs without prior hypotheses.

The paper provides the first evidence of widespread antiphage innate immunity in Antarctic hypolith communities, showing phages actively challenge niche communities through dynamic host-phage interactions.

This study investigates polyploidy in Neobatrachus frogs, finding that tetraploids have higher genetic diversity and may avoid climate-induced habitat loss compared to diploids.

The paper develops a probabilistic framework for inferring ancient whole genome duplications by accounting for gene tree and reconciliation uncertainty, and applies it to land plants.

This study uses digital organisms to simulate the impact of whole genome duplication on evolution under different environmental conditions, finding that duplicated genomes increase adaptive potential during extinction events.

The paper identifies a conserved gene cluster for cercosporin biosynthesis across multiple fungal pathogens, expands its known production to the genus Colletotrichum, and reveals additional genes critical for toxin synthesis.
