Background Biological invasions are a major ecological and socio-economic problem in
many parts of the world. Despite an explosion of research in recent decades, much remains …

The duplication of an entire genome is no small affair. Whole genome duplication (WGD) is
a dramatic mutation with long-lasting effects, yet it occurs repeatedly in all eukaryotic …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Spartina species of the mid-low intertidal areas are powerful ecological engineers that are
highly valued where they are native. Elsewhere, they overgrow native salt marsh and open …

Allopolyploidy results from two events: the merger of divergent genomes and genome
duplication. Both events have important functional consequences for the evolution and …

This article describes the use of cytogenomic and molecular approaches to explore the
origin and evolution of Cardamine schulzii, a textbook example of a recent allopolyploid, in …

The convergence of distinct lineages upon interspecific hybridisation, including when
accompanied by increases in ploidy (allopolyploidy), is a driving force in the origin of many …

Spartina alterniflora (Spartina) is the only halophyte in the salt marsh. However, the
molecular basis of its high salt tolerance remains elusive. In this study, we used Pacific …

Whole genome duplication (WGD) is widespread in flowering plants and is a driving force in
angiosperm diversification. The redundancy introduced by WGD allows the evolution of …

Polyploidy and recurrent interspecific hybridization represent major features of Spartina
evolution, resulting in several superimposed divergent genomes that coexist in the currently …
