Extensive chromosomal repatterning and the evolution of sterility barriers in hybrid sunflower species
Z Lai, T Nakazato, M Salmaso, JM Burke, S Tang… - Genetics, 2005 - academic.oup.com
New species may arise via hybridization and without a change in ploidy. This process,
termed homoploid hybrid speciation, is theoretically difficult because it requires the …

Multiple chromosomal inversions contribute to adaptive divergence of a dune sunflower ecotype
Both models and case studies suggest that chromosomal inversions can facilitate adaptation
and speciation in the presence of gene flow by suppressing recombination between locally …

Genomic islands of divergence are not affected by geography of speciation in sunflowers
Genomic studies of speciation often report the presence of highly differentiated genomic
regions interspersed within a milieu of weakly diverged loci. The formation of these …
