Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

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

Many organisms are currently polyploid, or have a polyploid ancestry and now have
secondarily'diploidized'genomes. This finding is surprising because retained whole-genome …

Hybrids such as maize (Zea mays) or domestic dog (Canis lupus familiaris) grow bigger and
stronger than their parents. This is also true for allopolyploids such as wheat (Triticum spp.) …

Twenty‐five years ago, Arabidopsis thaliana emerged as the model organism of choice for
research in plant biology. A consensus was reached about the need to focus on a single …

With the emergence of high‐throughput methods in plant biology, the importance of long‐
term projects characterized by incremental advances involving multiple laboratories can …

Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

All plant and animal species arise by speciation—the evolutionary splitting of one species
into two reproductively incompatible species. But until recently our understanding of the …

Incompatibilities in interspecific hybrids, such as sterility and lethality, are widely observed
causes of reproductive isolation and thus contribute to speciation. Because hybrid …
