Pervasive historical introgression across oak phylogeny shapes gene expression

This study shows that introgression is widespread across oak phylogeny and affects gene expression through cis-regulation and DNA methylation decay.

The effect of genome organisation on selection efficiency in two contrasted plant species

The paper investigates how mutational pleiotropy, expression level, and network connectivity affect the distribution of fitness effects of new mutations across the genome in two plant species.

The contribution of recent and historical demographic histories to genomic diversity and conservation status in plant species

This study assesses conservation status in 101 plant species by analyzing demographic parameters and genomic diversity, finding that census size is the best predictor of extinction risk.

When South meets North: a joint contact zone coinciding with environmental gradients in three boreal tree species

This study examines genetic structuring and local adaptation in three boreal tree species along a latitudinal gradient, revealing shared and species-specific patterns of gene flow and environmental adaptation.

Estimating the reduction in genetic diversity from background selection under non-equilibrium demography and partial selfing

This study estimates the reduction in genetic diversity from background selection in populations with non-equilibrium demography and partial selfing, finding weak effects in outcrossers and stronger effects in selfers.

Stabilising selection and ecological trade-offs underpin coexistence in a tropical flora

This study investigates genomic mechanisms of coexistence in a tropical flora, finding stabilising selection and ecological trade-offs between defence and growth.

Gene copy number variation (gCNV) contributes to adaptation along environmental gradient

This study shows that gene copy number variations (gCNVs) contribute to local adaptation in spruce species by affecting environmental stress response genes and quantitative traits.

Amino acid properties, substitution rates, and the nearly neutral theory

The paper tests if amino acid properties affect substitution rates, finding that larger physicochemical differences between amino acids correlate with lower substitution rates across multiple datasets.

Conserved Evolutionary Response to Whole Genome Duplication in Angiosperms Revealed Using High Resolution Gene Expression Profiling

This study identifies conserved meiotic gene expression patterns in autopolyploid plants across angiosperms, supporting a shared evolutionary response to whole genome duplication.

Complex Polyploids: Origins, Genomic Composition, and Role of Introgressed Alleles

The paper reconstructs the evolutionary history of Betula pubescens, showing it originated from an autoploid event and later hybridized with multiple species, with introgressed alleles contributing to climate adaptation and meiotic stability.

Separating phases of allopolyploid evolution with resynthesized and natural Capsella bursa-pastoris

The paper compares phenotypic and transcriptomic changes in natural and resynthesized allopolyploids of Capsella bursa-pastoris to distinguish short-term and long-term evolutionary effects.

The role of relatedness within a neighborhood in plant-to-plant interaction: effect on height growth and rust damage in Populus nigra

The paper examines how local relatedness affects tree height and rust damage in Populus nigra, finding that incorporating relatedness into genomic models improves rust resistance predictions but has limited overall effect.

Divergent selection predating the Last Glacial Maximum mainly acted on macro-phenotypes in Norway spruce

This study shows that divergent selection on macro-phenotypes in Norway spruce predates the Last Glacial Maximum, with stem diameter being under selection while tracheid dimensions and juvenile growth are not.

Variation in competitive ability with mating system, ploidy and range expansion in four Capsella species

The paper compares competitive ability across four Capsella species with different mating systems and ploidy levels, finding selfing species are more sensitive to competition than outcrossers, with ploidy and range expansion influencing this sensitivity.

Local adaptation and maladaptation during the worldwide range expansion of a self-fertilizing plant

The paper examines local adaptation and maladaptation in Capsella bursa-pastoris during its global range expansion by analyzing genetic diversity, phenology, and SNP correlations with environmental factors across three continents.

Parental legacy, demography, and introgression influenced the evolution of the two subgenomes of the tetraploid Capsella bursa-pastoris (Brassicaceae)

This study examines how two subgenomes in the allotetraploid Capsella bursa-pastoris evolved and interacted across three populations, finding differential effects of introgression, selection, and population size.
