Inheritance of chloroplast DNA is not strictly maternal in Silene vulgaris (Caryophyllaceae): evidence from experimental crosses and natural populations.
Chloroplast DNA (cpDNA) is maternally inherited in the majority, but not all, of angiosperm species. The mode of inheritance of cpDNA is a critical determinant of its molecular evolution and of its population genetic structure. Here, we present the results of investigations of the inheritance of cpDNA in Silene vulgaris, a plant used in a variety of studies in which cpDNA is an important compon...
متن کاملPaternal leakage and heteroplasmy of mitochondrial genomes in Silene vulgaris: evidence from experimental crosses.
The inheritance of mitochondrial genetic (mtDNA) markers in the gynodioecious plant Silene vulgaris was studied using a series of controlled crosses between parents of known mtDNA genotype followed by quantitative PCR assays of offspring genotype. Overall, approximately 2.5% of offspring derived from crosses between individuals that were homoplasmic for different mtDNA marker genotypes showed e...
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 کاملin 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 کاملWithin/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...
