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 ...
متن کاملInbreeding effects on progeny sex ratio and gender variation in the gynodioecious Silene vulgaris (Caryophyllaceae).
In gynodioecious species, sex expression is generally determined through cytoplasmic male sterility genes interacting with nuclear restorers of the male function. With dominant restorers, there may be an excess of females in the progeny of self-fertilized compared with cross-fertilized hermaphrodites. Moreover, the effect of inbreeding on late stages of the life cycle remains poorly explored. H...
متن کاملA new record and some rediscovered endemic Silene (Caryophyllaceae) species in Iran
Silene is represented by c. 110 species in flora of Iran which growing mainly in the mountainous areas. During several expeditions to different regions of Iran (Tehran, Semnan, Kerman, Kermanshah and Kohgiluyeh va Boyer-Ahmad Provinces) some interesting specimens were collected. S. caucasica, is introduced as a new record for the flora of Iran. Five interesting and very restricted Iranian endem...
متن کاملGynodioecy in Silene Vulgaris (caryophyllaceae): Progeny Success, Experimental Design, and Maternal Effects
This study documents the comparative success of seeds and seedlings of the perennial gynodioecious-gynomonoecious weed, Silene vulgaris. in the greenhouse. The importance of experimental design is stressed by comparing two different statistical analyses ofthe data. Seeds were obtained from artificial pollinations in the field: self-fertilization of hermaphrodites, and crossfertilizations of bot...
متن کاملA 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...
