Speciation mechanisms

We study speciation mechanisms in the hybridizing sister species Silene latifolia and S. dioica. These species have separate sexes (unusual for plants) with sex determination through comparatively recently evolved X and Y sex chromosomes. Our main questions include:

Which reproductive barriers are most important?

How are reproductive barriers controlled genetically and what is the role of sex chromosomes in this process?
