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

Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

Arabidopsis thaliana serves as a model organism for the study of fundamental physiological,
cellular, and molecular processes. It has also greatly advanced our understanding of …

Genetic data often exhibit patterns broadly consistent with'isolation by distance'—a
phenomenon where genetic similarity decays with geographic distance. In a heterogeneous …

Harnessing natural genetic variation is an established alternative to artificial genetic
variation for investigating the molecular dialog between partners in plant pathosystems …

Uncovering the genetic basis of agronomic traits in crop landraces that have adapted to
various agro-climatic conditions is important to world food security. Here we have …

Although pioneered by human geneticists as a potential solution to the challenging problem
of finding the genetic basis of common human diseases,, genome-wide association (GWA) …

Background Phylogenetic trees are widely used for genetic and evolutionary studies in
various organisms. Advanced sequencing technology has dramatically enriched data …

The plant Arabidopsis thaliana occurs naturally in many different habitats throughout
Eurasia. As a foundation for identifying genetic variation contributing to adaptation to diverse …

Motivation: Clustering of individuals into populations on the basis of multilocus genotypes is
informative in a variety of settings. In population-genetic clustering algorithms, such as …
