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

Abstract The Brassicaceae (Cruciferae) family, owing to its remarkable species, genetic, and
physiological diversity as well as its significant economic potential, has become a model for …

Advances in recent years have revolutionized our understanding of both the context and
occurrence of polyploidy in plants. Molecular phylogenetics has vastly improved our …

Assessing the relative importance of the various pathways to diversification is a central goal
of biodiversity researchers. For plant biologists, and increasingly across the spectrum of …

Allo-octoploid cultivated strawberry (Fragaria× ananassa) originated through a combination
of polyploid and homoploid hybridization, domestication of an interspecific hybrid lineage …

Despite the role of polyploidy in multiple evolutionary processes, its impact on plant
diversification remains controversial. An increased polyploid frequency may facilitate …

Chromosome number and genome variation in flowering plants have stimulated growing
speculation about the ancestral chromosome number of angiosperms, but estimates so far …

Comparisons of flowering plant genomes reveal multiple rounds of ancient polyploidy
characterized by large intragenomic syntenic blocks. Three such whole-genome duplication …

Whole‐genome duplications (WGD s) are widespread and prevalent in vascular plants and
frequently coincide with major episodes of global and climatic upheaval, including the mass …

If particular traits consistently affect rates of speciation and extinction, broad
macroevolutionary patterns can be interpreted as consequences of selection at high levels …
