Genomic evidence for supergene control of Darwin's 'complex marriage arrangement' - the tristylous floral polymorphism

The paper identifies two supergenes controlling tristyly in Eichhornia paniculata, with specific gene expression patterns and evolutionary age estimates supporting their role in the polymorphism.

Phylogenomics resolves key relationships in Rumex and uncovers a dynamic history of independently evolving sex chromosomes

This study uses phylogenomic analysis of Rumex species to resolve sex chromosome evolution, finding two independent origins and chromosomal rearrangements without adaptive expansion support.

Phased assembly of neo-sex chromosomes reveals extensive Y degeneration and rapid genome evolution in Rumex hastatulus

The paper studies Y chromosome degeneration in Rumex hastatulus by analyzing phased genome assemblies of old and new sex chromosomes, finding extensive gene loss and transposable element expansion on the Y chromosome.

Genome size and repeat content contribute to a complex architecture of flowering time in Amaranthus tuberculatus

This study examines genome size and repeat content variation in Amaranthus tuberculatus, finding that larger genomes correlate with slower flowering times, but polygenic and gene copy number variants have greater impact on flowering time adaptation.

Rapid weed adaptation and range expansion in response to agriculture over the last two centuries

The paper studies how modern agriculture has driven the evolution and range expansion of common waterhemp over the last two centuries through genome analysis of historical and present-day samples.

Genomic signatures of hybridization on the neo-X chromosome of Rumex hastatulus

The paper examines gene flow and reproductive isolation in Rumex hastatulus hybrid zones, finding that the neo-X chromosome contributes to inter-cytotype differentiation.

Selective ancestral sorting and de novo evolution in the agricultural invasion of Amaranthus tuberculatus

This study investigates how A. tuberculatus adapts to agricultural environments through ancestral sorting and de novo evolution, finding both preadaptation and new adaptations.

Repeated origins, gene flow, and allelic interactions of herbicide resistance mutations in a widespread agricultural weed

This study investigates the evolutionary history of herbicide resistance mutations in common waterhemp, finding parallel origins, gene flow, and allelic interactions shaping their spread and persistence.

Widespread Recombination Suppression Facilitates Plant Sex Chromosome Evolution

The paper investigates recombination suppression in a plant species with a young neo-sex chromosome, finding that low recombination rates preceded sex linkage.

Multiple modes of convergent adaptation in the spread of glyphosate-resistant Amaranthus tuberculatus

This study investigates the genetic mechanisms of glyphosate resistance in Amaranthus tuberculatus, finding multiple modes of convergent adaptation through gene flow and de novo mutations in different populations.

Ancestral and neo-sex chromosomes contribute to population divergence in a dioecious plant

This study examines how ancestral and neo-sex chromosomes contribute to population divergence in the dioecious plant Rumex hastatulus by analyzing genetic differentiation and demographic history.

Towards the new normal: Transcriptomic and genomic changes in the two subgenomes of a 100,000 years old allopolyploid, Capsella bursa-pastoris

This study examines transcriptomic and genomic changes in the subgenomes of an ancient allopolyploid plant, finding strong parental legacy and adaptive expression biases in different tissues.

Transposable elements are important contributors to standing variation in gene expression in Capsella grandiflora

This study shows that transposable elements (TEs) significantly contribute to gene expression variation in Capsella grandiflora, with rare TE variants predominantly causing downregulation, more so than rare SNPs.

The effects of haploid selection on Y chromosome evolution in two closely related dioecious plants

This study investigates haploid selection's impact on Y chromosome evolution in two Rumex species, finding genes with high pollen expression bias are more common on sex chromosomes and Y chromosomes show enrichment for pollen expression.
