Non-coding RNA may be associated with cytoplasmic male sterility in Silene vulgaris.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Cytoplasmic male sterility (CMS) is a widespread phenomenon in flowering plants caused by mitochondrial (mt) genes. CMS genes typically encode novel proteins that interfere with mt functions and can be silenced by nuclear fertility-restorer genes. Although the molecular basis of CMS is well

A quantitative genetic analysis of nuclear-cytoplasmic male sterility in structured populations of Silene vulgaris.

Prijava / prijava

Gynodioecy, the coexistence of functionally female and hermaphroditic morphs within plant populations, often has a complicated genetic basis involving several cytoplasmic male-sterility factors and nuclear restorers. This complexity has made it difficult to study the genetics and evolution of

Intraspecific variation in mitochondrial genome sequence, structure, and gene content in Silene vulgaris, an angiosperm with pervasive cytoplasmic male sterility.

Prijava / prijava

In angiosperms, mitochondrial-encoded genes can cause cytoplasmic male sterility (CMS), resulting in the coexistence of female and hermaphroditic individuals (gynodioecy). We compared four complete mitochondrial genomes from the gynodioecious species Silene vulgaris and found unprecedented amounts

The male-sterility polymorphism of Silene vulgaris: analysis of genetic dat from two populations and comparison with Thymus vulgaris.

Prijava / prijava

Results are given of genetic studies of male sterility using plants from two natural populations from Sussex, England. Both populations have substantial frequencies of females, approximately 0.25 in population 1 and 0.60 in population 3. As in the few other gynodioecious populations studied in

Nonneutral evolution of organelle genes in Silene vulgaris.

Prijava / prijava

Knowledge of mitochondrial gene evolution in angiosperms has taken a dramatic shift within the past decade, from universal slow rates of nucleotide change to a growing realization of high variation in rates among lineages. Additionally, evidence of paternal inheritance of plant mitochondria and

Fine scale spatial structuring of sex and mitochondria in Silene vulgaris.

Prijava / prijava

Fine scale spatial structure (FSSS) of cytoplasmic genes in plants is thought to be generated via founder events and can be amplified when seeds germinate close to their mother. In gynodioecious species these processes are expected to generate FSSS in sex ratio because maternally inherited

Inbreeding effects on progeny sex ratio and gender variation in the gynodioecious Silene vulgaris (Caryophyllaceae).

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

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

Mitochondrial DNA diversity, population structure, and gender association in the gynodioecious plant Silene vulgaris.

Prijava / prijava

A highly variable mitochondrial DNA (mtDNA) restriction fragment length polymorphism (RFLP) locus is used to assess the population structure of mitochondrial genomes in the gynodioecious plant Silene vulgaris at two spatial scales. Thirteen mtDNA haplotypes were identified within 250 individuals

Variation in plastid genomes in the gynodioecious species Silene vulgaris.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Gynodioecious species exist in two sexes - male-sterile females and hermaphrodites. Male sterility in higher plants often results from mitonuclear interaction between the CMS (cytoplasmic male sterility) gene(s) encoded by mitochondrial genome and by nuclear-encoded restorer genes.

Variable populations within variable populations: quantifying mitochondrial heteroplasmy in natural populations of the gynodioecious plant Silene vulgaris.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Populations of mitochondria reside within individuals. Among angiosperms, these populations are rarely considered as genetically variable entities and typically are not found to be heteroplasmic in nature, leading to the widespread assumption that plant mitochondrial populations are homoplasmic.

Homologous recombination changes the context of Cytochrome b transcription in the mitochondrial genome of Silene vulgaris KRA.

Prijava / prijava

Silene vulgaris (bladder campion) is a gynodioecious species existing as two genders - male-sterile females and hermaphrodites. Cytoplasmic male sterility (CMS) is generally encoded by mitochondrial genes, which interact with nuclear fertility restorer genes. Mitochondrial genomes of

Mitochondrial heteroplasmy and paternal leakage in natural populations of Silene vulgaris, a gynodioecious plant.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

It is currently thought that most angiosperms transmit their mitochondrial genomes maternally. Maternal transmission limits opportunities for genetic heterogeneity (heteroplasmy) of the mitochondrial genome within individuals. Recent studies of the gynodioecious species Silene vulgaris and Silene

Offspring sex ratio under inbreeding and outbreeding in a gynodioecious plant.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Silene vulgaris is a gynodioecious plant native to Eurasia and now found throughout much of North America. Using hermaphrodite plants from three geographic regions (Stamford, NY; Broadway,VA; and Giles Co., VA) and four local populations within each region, we employed a hierarchical crossing design

Sex inheritance in gynodioecious species: a polygenic view.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Gynodioecy is defined as the coexistence of two different sexual morphs in a population: females and hermaphrodites. This breeding system is found among many different families of angiosperms and is usually under nucleo-cytoplasmic inheritance, with maternally inherited genes causing male sterility

Paternal effects on seed germination: a barrier to the genetic assimilation of an endemic plant taxon?

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

We used a crossing experiment to investigate post-zygotic barriers that might limit introgression between a pair of closely-related, gynodioecious plant species--the widespread weed Silene vulgaris and the local Swedish endemic S. uniflora ssp. petraea. The study not only considered the effects of
