Gene flow is a fundamental evolutionary force in adaptation that is especially important to
understand as humans are rapidly changing both the natural environment and natural levels …

Reproductive isolation in plants occurs through multiple barriers that restrict gene flow
between populations, but their origins remain uncertain. Work in the past decade has shown …

The term “landrace” has generally been defined as a cultivated, genetically heterogeneous
variety that has evolved in a certain ecogeographical area and is therefore adapted to the …

It has long been recognized that hybridization and polyploidy are prominent processes in
plant evolution. Although classically recognized as significant in speciation and adaptation …

Understanding the phenotypic and molecular mechanisms that contribute to genetic
diversity between and within species is fundamental in studying the evolution of species. In …

Understanding how pollen moves between species is critical to understanding speciation,
diversification, and evolution of flowering plants. For co-flowering species that share …

Powerful scientific techniques have caused dramatic expansion of genetically modified
crops leading to altered agricultural practices posing direct and indirect environmental …

The notion of species as reproductively isolated units related through a bifurcating tree
implies that gene trees should generally agree with the species tree and that sister taxa …

The apple (Malus domestica [Suckow] Borkh.) is one of the most economically and culturally
significant fruits in the world today, and it is grown in all temperate zones. With over a …

Evaluating the factors that drive patterns of population differentiation in plants is critical for
understanding several biological processes such as local adaptation and incipient …
