Trait evolution linked to climatic shifts contributes to adaptive divergence in an alpine carnation (Dianthus sylvestris)

This study shows that climatic shifts drive adaptive divergence in Dianthus sylvestris by shaping life-history strategies through selection on growth and reproductive traits at different elevations.

Life history traits mediate elevational adaptation in a perennial alpine plant

This study shows how life history traits mediate elevational adaptation in Dianthus carthusianorum through genotype x environment interactions and trade-offs between reproduction and survival.

Evolution of sex-biased gene expression during transitions to separate sexes in the Silene genus

This study examines the evolution of sex-biased gene expression during transitions to separate sexes in the Silene genus, showing male-biased genes emerge first and positive selection affects some SBGs.

Sequential colonization events with restricted gene flow in a widespread European carnation species

This study investigates the colonization history of Dianthus carthusianorum using genome-wide SNPs and ABC-RF to reveal sequential East-West colonization events with restricted gene flow.

Population genomics and epigenomics provide insights into the evolution of facultative asexuality in plants

The paper analyzes population genomes and epigenomes of Spirodela polyrhiza to show low genomic diversity and DNA methylation levels, with natural selection shaping asexual reproduction traits.

Ancient methicillin-resistant Staphylococcus aureus: expanding current knowledge using molecular epidemiological characterization of a Swiss legacy collection

The paper characterizes ancient MRSA isolates from 1965-1987 and compares them to modern isolates, identifying novel sequence types and lineage dynamics.

Detecting directional epistasis and dominance from cross-line analyses in alpine populations of Arabidopsis thaliana

The paper examines non-additive genetic effects in Arabidopsis thaliana by analyzing crosses between inbred lines, finding mid-parent heterosis for biomass and outbreeding depression for siliques.

Genomic evidence for rapid speciation and gene flow between sympatric carnivorous Nepenthes pitcher plants

The paper uses ddRAD-seq to analyze genetic divergence and introgression in sympatric Nepenthes species, finding high divergence with limited recent gene flow and low divergence with ongoing hybridization.

Adaptive evolution of carnivory in Nepenthes pitcher plants: a comparative transcriptomics and proteomics perspective

This study identifies genes under positive selection in Nepenthes pitcher plants, showing a bias towards carnivory-related genes and trap-expressed genes.

Unravelling drivers of local adaptation through Evolutionary Functional-Structural Plant modelling

This study develops an evolutionary functional-structural plant model to investigate the drivers of local adaptation in Dianthus carthusianorum along elevation gradients, finding abiotic factors predominantly drive adaptation.

Climate-induced range shifts drive adaptive response via spatio-temporal sorting of alleles

The paper shows that climate-induced range shifts in Dianthus sylvestris led to adaptive responses through spatio-temporal sorting of alleles during post-glacial expansions.

The UV RESISTANCE LOCUS 8-Mediated UV-B Response Is Required Alongside CRYPTOCHROME1 For Plant Survival Under Sunlight In The Field

This study shows that UVR8 and CRY1 work together in Arabidopsis to help plants survive UV-B radiation in natural conditions, with UVR8 playing a key role in long-term survival.

Identifying loci under selection via explicit demographic models

This paper introduces LSD, a method to identify loci under selection by incorporating explicit demographic models, showing it outperforms existing methods and detects genetic trade-offs in Antirrhinum majus.

Dioecy in plants: an evolutionary dead end? Insights from a population genomics study in the Silene genus

This study uses population genomics to challenge the evolutionary dead end hypothesis of dioecy in Silene species, finding increased genetic diversity and adaptation potential in dioecious species.

Adaptation to local climate in a multi-trait space: evidence from silver fir (Abies alba Mill.) populations across a heterogeneous environment

The paper examines local adaptation in silver fir populations by analyzing genetic and phenotypic data to show climate-driven divergence in growth strategies.

Genomic imprinting mediates dosage compensation in a young plant XY system

The paper identifies genomic imprinting as a dosage compensation mechanism in the young XY system of Silene latifolia, compensating for reduced Y gene expression in males.
