Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

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 …

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

Polyploids can be defined as organisms with one or more additional chromosome sets with
respect to the number most frequently found in nature for a given species. Triploids …

Most flowering plants have been shown to be ancient polyploids that have undergone one
or more whole genome duplications early in their evolution. Furthermore, many different …

Polyploidy has contributed to the evolution of eukaryotes, particularly flowering plants. The
genomic consequences of polyploidy have been extensively studied, but the mechanisms …

Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

Polyploidy, or the presence of two or more diploid parental genome sets within an organism,
is found to an amazing degree in higher plants. In addition, many plant species traditionally …

The comparison of the chromosome numbers of today's species with common reconstructed
paleo-ancestors has led to intense speculation of how chromosomes have been rearranged …

A long-standing hypothesis in evolutionary biology is that polyploid plants have a fitness
advantage over diploids in climatically variable or extreme habitats. Here we provide the first …
