TL;DR: It is found that the genomic architecture of flowering time has been shaped by the most recent whole-genome duplication, which suggests that ancient paralogues can remain in the same regulatory networks for dozens of millions of years.
Journal ArticleDOI
Hybridization and extinction.
Marco Todesco,Mariana A. Pascual,Gregory L. Owens,Katherine L. Ostevik,Brook T. Moyers,Brook T. Moyers,Sariel Hübner,Sylvia M. Heredia,Min A. Hahn,Celine Caseys,Dan G. Bock,Loren H. Rieseberg,Loren H. Rieseberg +12 more
TL;DR: It is found that while extinction risk is highly situation dependent, genetic swamping is much more frequent than demographic swamping, and it is concluded that halting the introduction of hybridization‐prone exotics and restoring mature and diverse habitats that are resistant to hybrid establishment should be management priorities.
Journal ArticleDOI
Massive haplotypes underlie ecotypic differentiation in sunflowers

TL;DR: Resequencing analyses of three species of wild sunflowers identify large non-recombining haplotype blocks that correlate with ecologically relevant traits, soil and climate characteristics, and that differentiate species ecotypes.
Journal ArticleDOI
Sunflower pan-genome analysis shows that hybridization altered gene content and disease resistance

TL;DR: A sunflower pan-genome determined by sequencing about 500 accessions showed that introgression from the wild species has profoundly shaped the cultivar gene pool and contributed disease resistance genes.
Journal ArticleDOI
Gene flow and selection interact to promote adaptive divergence in regions of low recombination
Kieran Samuk,Gregory L. Owens,Kira E. Delmore,Sara E. Miller,Diana J. Rennison,Dolph Schluter +5 more
TL;DR: This study provides the first statistical evidence that the interaction of gene flow and selection biases divergence toward regions of low recombination, potentially favouring divergence and adaptive evolution in these regions over others.
