Hybrid zones between cytotypes with different ploidy levels are particularly interesting for
studying the ecology and the evolution of reproductive interactions between closely related …

Hybridization plays a central role in plant evolution, but its overall importance in fungi is
unknown. New plant pathogens are thought to arise by hybridization between formerly …

We investigated concerted evolution of rRNA genes in multiple populations of Tragopogon
mirus and T. miscellus, two allotetraploids that formed recurrently within the last 80 years …

In many polyploid species, polyploids often have different suites of floral traits and different
flowering times than their diploid progenitor species. We hypothesized that such differences …

The wide distribution of polyploidy among plants has led to a variety of theories for the
evolutionary advantages of polyploidy. Here we claim that the abundance of polyploidy may …

Polyploidy creates severe genetic bottlenecks, contributing to the genetic vulnerability of
leading crops. Cultivated peanut is thought to be of monophyletic origin, harboring relatively …

Summary 1 Theoretical models indicate that coexistence of diploid and polyploid individuals
in sympatric populations is unlikely when mating is random among cytotypes and hybrids …

Two new polyploid species of Senecio have originated in the British Isles in recent times
following hybridization between native S. vulgaris (2 n= 40) and introduced S. squalidus (2 …

Allopolyploidy is a prominent mode of speciation in higher plants. Due to the coexistence of
closely related genomes, a successful allopolyploid must have the ability to invoke and …

As anthropogenic environmental changes spread and intensify across the planet,
conservation biologists have to analyze dynamics at large spatial and temporal scales …
