Genetic polymorphism varies among species and within genomes, and has important
implications for the evolution and conservation of species. The determinants of this variation …

As climate change progresses, we are observing widespread changes in phenotypes in
many plant populations. Whether these phenotypic changes are directly caused by climate …

Understanding why some species have more genetic diversity than others is central to the
study of ecology and evolution, and carries potentially important implications for …

The transition from outcrossing to self-fertilization is one of the most common evolutionary
changes in plants, yet only about 10–15% of flowering plants are predominantly selfing. To …

Recombination is typically thought of as a symmetrical process resulting in large-scale
reciprocal genetic exchanges between homologous chromosomes. Recombination events …

Identifying traits that affect rates of speciation and extinction and, hence, explain differences
in species diversity among clades is a major goal of evolutionary biology. Detecting such …

While seed‐propagated crops have contributed many evolutionary insights, evolutionary
biologists have often neglected clonally propagated crops. We argue that widespread …

We review and analyze the available literature on the frequency and distribution of self-
incompatibility (SI) among angiosperms and find that SI is reported in more than 100 families …

Among the fundamental evolutionary forces, recombination arguably has the largest impact
on the practical work of plant breeders. Varying over 1,000-fold across the maize genome …

Mimulus guttatus and M. nasutus are an evolutionary and ecological model sister species
pair differentiated by ecology, mating system, and partial reproductive isolation. Despite …
