Hybridization has long been recognized as a fundamental evolutionary process in plants
but, until recently, our understanding of its phylogenetic distribution and biological …

Studying the genetics of adaptation to new environments in ecologically and industrially
important tree species is currently a major research line in the fields of plant science and …

Northern Hemisphere forests changed drastically in the early Eocene with the diversification
of the oak family (Fagaceae). Cooling climates over the next 20 million years fostered the …

Introgression can be an important source of new alleles for adaption under rapidly changing
environments, perhaps even more important than standing variation. Though introgression …

The tree of life is highly reticulate, with the history of population divergence emerging from
populations of gene phylogenies that reflect histories of introgression, lineage sorting and …

The genus Quercus is among the most widespread and species‐rich tree genera in the
northern hemisphere. The extraordinary species diversity in America and Asia together with …

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

Species‐level taxonomy derives from empirical sources (data and techniques) that assess
the existence of spatiotemporal evolutionary lineages via various species “concepts.” These …

Hybridization and resulting introgression are important processes shaping the tree of life
and appear to be far more common than previously thought. However, how the genome …

Studies of plants have been instrumental for revealing how new species originate. For
several decades, botanical research has complemented and, in some cases, challenged …
