Our goal was to gain insight into the mechanisms of pollinator-mediated selection that underlies floral trait divergence within the genus.

متن کاملIntrogressive Hybridization between Anciently Diverged Lineages of Silene (Caryophyllaceae)
Hybridization has played a major role during the evolution of angiosperms, mediating both gene flow between already distinct species and the formation of new species. Newly formed hybrids between distantly related taxa are often sterile. For this reason, interspecific crosses resulting in fertile hybrids have rarely been described to take place after more than a few million years after divergen...
