A high-throughput amplicon-based method for estimating outcrossing rates
Plant Methods, 2019 Background The outcrossing rate is a key determinant of the population-genetic structure of species and their long-term evolutionary trajectories.

Natural outcrossing rate in Vernonia galamensis
Plant Breeding, 2004 Abstract Vernonia galamensis is a potential new industrial crop growing wild in Ethiopia. The seed oil is rich in vernolic acid, an epoxy fatty acid, which is of interest for oleochemical uses. Basic information on the reproductive system of Vernonia is still very limited.

Variable opportunities for outcrossing result in hotspots of novel genetic variation in a pathogen metapopulation [PDF]
eLife, 2019 Many pathogens possess the capacity for sex through outcrossing, despite being able to reproduce also asexually and/or via selfing. Given that sex is assumed to come at a cost, these mixed reproductive strategies typical of pathogens have remained ...

Stability of Outcrossing Rates in Eucalyptus globulus Seedlots [PDF]
, 2004 Eucalyptus globulus has a mixed mating system and selfing leads to severe inbreeding depression. Thus, outcrossing rate is an important measure of seed quality in this species.

Epigenetics, 2022 Hybridization is a major source of evolutionary innovation. In plants, epigenetic mechanisms can help to stabilize hybrid genomes and contribute to reproductive isolation, but the relationship between genetic and epigenetic changes in animal hybrids is ...

Estimation of Outcrossing in Basil [PDF]
HortScience, 1992 The rate of outcrossing in basil [eight accessions of Ocimum basilicum L. and one accession purported to be O. kilimandscharicum Guerke (`Juicy Fruit')] was estimated using a purple seedling marker in `Dark Opal' (O. basilicum).

Natural variation of outcrossing in the hermaphroditic nematode Pristionchus pacificus [PDF]
, 2009 Background: Evolution of selfing can be associated with an increase in fixation of deleterious mutations, which in certain conditions can lead to species extinction.

Reconstruction of the High Stigma Exsertion Rate Trait in Rice by Pyramiding Multiple QTLs
Frontiers in Plant Science, 2022 Asian cultivated rice is a self-pollinating crop, which has already lost some traits of natural outcrossing in the process of domestication. However, male sterility lines (MSLs) need to have a strong outcrossing ability to produce hybrid seeds by ...

The abundance of pollen coat small signaling proteins shows limited convergence between independent selfing transitions in Arabidopsis and Capsella. [PDF]
New PhytolSummary In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self‐fertilization, often resulting in the ‘selfing syndrome’ (e.g. reduced flower size and loss of scent). However, potentially overlooked changes concern the pollen coat, which plays a role in different aspects
