Transposable Element Evolution in the Allotetraploid Capsella bursa-pastoris

This study examines TE abundance in the allotetraploid Capsella bursa-pastoris and finds no genome-wide TE proliferation but increased retrotransposon abundance in gene-rich regions, suggesting relaxed selection over silencing breakdown.

Chromosomal distribution of cyto-nuclear genes in a dioecious plant with sex chromosomes

This study examines the chromosomal distribution of cyto-nuclear genes in a plant with sex chromosomes and finds no evidence supporting co-adaptation or sexual conflict hypotheses.

No evidence that sex and transposable elements drive genome size variation in evening primroses

The paper investigates the role of sex and transposable elements in genome size variation among evening primroses and finds no significant association.

Evidence for widespread positive and negative selection in coding and conserved noncoding regions of Capsella grandiflora

The paper analyzes selection pressures in Capsella grandiflora genomes, finding strong selection in coding regions and conserved noncoding regions, but weaker selection in most noncoding regions.
