Competition between recombination and epistasis can cause a transition from allele to genotype selection [PDF]
Biochemical and regulatory interactions central to biological networks are expected to cause extensive genetic interactions or epistasis affecting the heritability of complex traits and the distribution of genotypes in populations. However, the inference

How mating system impacts the genetic diversity of plants has long fascinated and puzzled evolutionary biologists. Numerous studies have shown that self-fertilising plants have less genetic diversity at both the population and species levels than ...

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]
To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare.

Heteranthery in Clarkia: pollen performance of dimorphic anthers contradicts expectations. [PDF]
Premise of the studyWild plant species that require the services of pollen-feeding insects for reliable pollination may evolve features that attract and reward their mutualistic partners.

Abstract The average frequency of observable outcrossing among 6 genotypes of southernpea (Vigna unguiculata (L.) Walp.) in a population of 9,987 plants was 0.59% and varied from 1.42% in AU 70.4 to 0% in Ala. 963.8G1-4. Outcrossing as high as 4.26% was recorded in a single plot of ‘Giant Blackeye’.

The scale of population structure in Arabidopsis thaliana [PDF]
The population structure of an organism reflects its evolutionary history and influences its evolutionary trajectory. It constrains the combination of genetic diversity and reveals patterns of past gene flow.

Highlight We show for the first time that abiotic stress during flowering can dramatically increase the proportion of progeny produced by outcrossing in a mixed-mating, insect-pollinated plant.

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

Abstract Malate dehydrogenase (MDH) isozyme variability in peach [Prunus persica (L.) Batsch.] cultivars allowed estimation of outcrossing. After correction for undetectable pollen (of the same genotype as the homozygous Mdh-aa female parents), mean rates of outcrossing of 33% in 1984 and 15% in 1985 were observed.

Evaluation of the risks of contaminating low erucic acid rapeseed with high erucic rapeseed and identification of mitigation strategies [PDF]
High erucic acid rapeseed (HEAR) oil is under increasing demand for various industrial applications. However, many growers are concerned that if they grow the crop, they will not be able to revert to other rapeseed varieties in the future due to the risk
