Breeding system of diploid sexuals within the Ranunculus auricomus complex and its role in a geographical parthenogenesis scenario

open access: yesEcology and Evolution, 2020
The larger distribution area of asexuals compared with their sexual relatives in geographical parthenogenesis (GP) scenarios has been widely attributed to the advantages of uniparental reproduction and polyploidy.

Characterization of Deleterious Mutations in Outcrossing Populations [PDF]

open access: yesGenetics, 1998
Abstract Deng and Lynch recently proposed estimating the rate and effects of deleterious genomic mutations from changes in the mean and genetic variance of fitness upon selfing/outcrossing in outcrossing/highly selfing populations. The utility of our original estimation approach is limited in outcrossing populations, since selfing may ...

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

open access: yesNew Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Microsatellite Primers for Camissoniopsis cheiranthifolia (Onagraceae) and Cross-Amplification in Related Species

open access: yesApplications in Plant Sciences, 2014
Premise of the study: We developed 24 nuclear microsatellite primers from an enriched genomic library for the Pacific coastal dune endemic Camissoniopsis cheiranthifolia to study the consequences of mating system differentiation, the genetics of species'

Outcrossing Techniques for Producing Artichoke Seed [PDF]

open access: yesHortScience, 1997
The artichoke, Cynara scolymus, is normally propagated by cuttings from mother plants; however, it is possible to produce some types of artichokes from seed. Methods used for producing open-pollinated seed of onion and carrots may be suitable for producing artichoke seed.

Population genomic signatures of founding events in autonomously self‐fertilizing plants: a test with Impatiens capensis

open access: yesNew Phytologist, EarlyView.
Summary Autonomously self‐fertilizing plants possess disproportionate abilities to found populations. Viewed from the metapopulation perspective, founding events should be frequent in such plants, but the intensity and timing of bottlenecks and recovery should vary among populations.

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, EarlyView.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Habitat Predicts Levels of Genetic Admixture in Saccharomyces cerevisiae

open access: yesG3: Genes, Genomes, Genetics, 2017
Genetic admixture can provide material for populations to adapt to local environments, and this process has played a crucial role in the domestication of plants and animals.

From recognition to response: integrated signaling pathways determining pollen acceptance and rejection in Brassicaceae

open access: yesNew Phytologist, EarlyView.
Summary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.

Estimation of the outcrossing rate for annual Asian wild rice under field conditions

open access: yesBreeding Science, 2012
The Asian wild rice, Oryza rufipogon, has partial outcrossing behavior and shows high levels of genetic variation. To estimate an accurate outcrossing rate of annual form of O.
