The paper investigates the role of ancient whole-genome duplications in crop domestication by analyzing the enrichment of paleologs in domestication candidate genes across 22 species.

This paper develops a nonlinear dynamics framework to analyze mutation-selection balance in tetraploids, revealing dominance-dependent bistability and altered temporal dynamics compared to diploids.

The paper develops a chromosome-scale reference genome and genetic map for yellow starthistle, identifies QTLs associated with invader traits, and finds structural variants and paleolog enrichment linked to invasion-related adaptations.

The paper tests the hypothesis that ancient polyploidy and low chromosome loss explain high chromosome numbers in ferns, finding similar paleopolyploidy rates but lower chromosome loss in ferns compared to angiosperms.

This study examines Chelicerate genomes to determine if whole genome duplications occurred in spiders and scorpions, finding no evidence for such events in their history.

SLEDGe uses a machine learning classifier with a Ks plot simulator to detect ancient whole-genome duplication signatures in genomic data with high accuracy.

The paper investigates the relationship between chromosome number and post-zygotic reproductive isolation in plants, finding no correlation.

The paper assesses how species tree topology affects the inference of ancient whole-genome duplications in angiosperms using different methods and phylogenetic hypotheses.

This study presents a de novo genome assembly of Datura wrightii and identifies differentially expressed genes and the role of tandem duplications in herbivore defense.

The paper develops a machine learning method to classify paleologs from whole genome duplications in plants, showing improved accuracy and efficiency compared to existing methods.

The paper confirms a two-step hybridization model for the formation of hexaploidy in Brassiceae and shows subgenomes have distinct loss rates but functionally compatible genes.

The paper presents RNA-seq data from 24 vascular plant species at Harvard Forest, assessing transcriptome quality and finding no significant difference in gene assembly between diploid and polyploid species.

The paper uses genomic data and written records to validate domestication events in Brassica rapa, finding support for specific genetic groups and domestication timelines.
