    • Complex Evolutionary Events at a Tandem Cluster of Arabidopsis thaliana Genes Resulting in a Single-Locus Genetic Incompatibility 

      Smith, Lisa M.; Bomblies, Kirsten; Weigel, Detlef (Public Library of Science, 2011)
      Non-additive interactions between genomes have important implications, not only for practical applications such as breeding, but also for understanding evolution. In extreme cases, genes from different genomic backgrounds ...
    • Evolutionary Dynamics of a Multiple-Ploidy System in Arabidopsis Arenosa 

      Arnold, Brian (2015-05-18)
      Whole-genome duplication (WGD), which leads to polyploidy, has been implicated in speciation and biological novelty. In plants, many species have experienced historical bouts of WGD or exhibit extant ploidy variation, which ...
    • Extending Coalescent Theory to Autotetraploids 

      Arnold, Brian John; Bomblies, Kirsten; Wakeley, John (The Genetics Society of America, 2012)
      We develop coalescent models for autotetraploid species with tetrasomic inheritance. We show that the ancestral genetic process in a large population without recombination may be approximated using Kingman’s standard ...
    • Genetic Adaptation Associated with Genome-Doubling in Autotetraploid Arabidopsis arenosa 

      Hollister, Jesse D.; Arnold, Brian John; Svedin, Elisabeth; Xue, Katherine Shaohua; Dilkes, Brian P.; Bomblies, Kirsten (Public Library of Science, 2012)
      Genome duplication, which results in polyploidy, is disruptive to fundamental biological processes. Genome duplications occur spontaneously in a range of taxa and problems such as sterility, aneuploidy, and gene expression ...
    • Genetic Architecture of Flowering-Time Variation in Arabidopsis thaliana 

      Salomé, Patrice A.; Bomblies, Kirsten; Laitinen, Roosa A.; Yant, Levi; Mott, Richard; Weigel, Detlef (The Genetics Society of America, 2011)
      The onset of flowering is an important adaptive trait in plants. The small ephemeral species Arabidopsis thaliana grows under a wide range of temperature and day-length conditions across much of the Northern hemisphere, ...
    • Horizontal transfer of expressed genes in a parasitic flowering plant 

      Xi, Zhenxiang; Bradley, Robert K; Wurdack, Kenneth J; Wong, KM; Sugumaran, M; Bomblies, Kirsten; Rest, Joshua S; Davis, Charles Cavender (BioMed Central, 2012)
      Background: Recent studies have shown that plant genomes have potentially undergone rampant horizontal gene transfer (HGT). In plant parasitic systems HGT appears to be facilitated by the intimate physical association ...
    • Local-Scale Patterns of Genetic Variability, Outcrossing, and Spatial Structure in Natural Stands of Arabidopsis thaliana 

      Bomblies, Kirsten; Yant, Levi; Laitinen, Roosa A.; Kim, Sang-Tae; Hollister, Jesse Dylan; Warthmann, Norman; Fitz, Joffrey; Weigel, Detlef (Public Library of Science, 2010)
      As Arabidopsis thaliana is increasingly employed in evolutionary and ecological studies, it is essential to understand patterns of natural genetic variation and the forces that shape them. Previous work focusing mostly on ...
    • Meiotic Adaptation to Genome Duplication in Arabidopsis arenosa 

      Yant, Levi; Hollister, J; Wright, K; Arnold, Brian John; Higgins, James D.; Franklin, F. Chris H.; Bomblies, Kirsten (Elsevier BV, 2013)
      Whole genome duplication (WGD) is a major factor in the evolution of multicellular eukaryotes, yet by doubling the number of homologs, WGD severely challenges reliable chromosome segregation [1, 2, 3], a process conserved ...
    • RADseq underestimates diversity and introduces genealogical biases due to nonrandom haplotype sampling 

      Arnold, Brian John; Corbett-Detig, Russ Brendan; Hartl, Daniel L.; Bomblies, Kirsten (Wiley Blackwell (Blackwell Publishing), 2013)
      Reduced representation genome-sequencing approaches based on restriction digestion are enabling large-scale marker generation and facilitating genomic studies in a wide range of model and nonmodel systems. However, sampling ...
