The genetic basis of hairlessness in Silene dioica (Caryophyllaceae)*

in Silene latifolia (Caryophyllaceae)

• Sex ratio polymorphism has been extensively studied in Silene latifolia, but it is neither known whether inbreeding (which is likely to occur under field conditions) affects it nor which of the proposed mechanisms (Y degeneration, X-linked drive) is more important. Both mechanisms predict reduced pollen performance. • In this study, females were crossed with pollen from related and unrelated ...

Within/between population crosses reveal genetic basis for siring success in Silene latifolia (Caryophyllaceae).

Divergence at reproductive traits can generate barriers among populations, and may result from several mechanisms, including drift, local selection and co-adaptation between the sexes. Intersexual co-adaptation can arise through sexually antagonistic co-evolution, a timely hypothesis addressed in animals but, to our knowledge, not yet in flowering plants. We investigated whether male and female...

A taxonomic study on the genus Silene (Caryophyllaceae) in Iran

The genus Silene includes 98 species in Iran, with 35 endemic to the Iranian plateau (26 species for Iran). The Iranian species are placed in 21 sections. In this article, the most important characteristics for the separation of the sections, relationships between the sections, and an identification key for the sections in Iran are presented. For each section a distribution map is provided. The...

Disentangling the Reticulate History of Polyploids in Silene (Caryophyllaceae)

A taxonomic study of Silene goniocaula (Caryophyllaceae) complex in Iran

By studying the type specimens and field works from locus classicus, it became clear that the two species of Silene eremicana and S. goniocaula which are considered as conspecific in the Flora Iranica are distinct species. Silene commelinifolia var. isophylla is considered as a synonym of S. eremicana. The numbers of herbarium specimens (voucher) are emended and the descriptions of each species...
