Studies of the strength and nature of reproductive isolation (RI) between species can greatly contribute to our understanding of speciation. Although the role of RI in speciation is well recognized, there is a dearth of information on the contributions of different barriers between related plant species. Here, we estimated multiple components of RI between two Mediterranean orchid sister species...

Polymorphism of postmating reproductive isolation within plant species

Scopece, Giovanni ; Lexer, Christian ; Widmer, Alex ; Cozzolino, Salvatore

In: Taxon, 2010, vol. 59, no. 5, p. 1367-1374

Speciation can be viewed as the evolution of reproductive isolation between formerly interbreeding populations. Recent years have seen great advances in our understanding of the genetic mechanisms underlying postmating reproductive isolation during plant speciation. Nevertheless, little is known about the early stages of species divergence and the evolution of reproductive isolation at the...
