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 …

Polyploidy, the condition of possessing more than two complete genomes in a cell, has
intrigued biologists for almost a century. Polyploidy is found in many plants and some animal …

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

Polyploidy has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …

Polyploidy, or whole-genome duplication (WGD), is an important genomic feature for all
eukaryotes, especially many plants and some animals. The common occurrence of …

Many previous studies have provided evidence for genome changes in polyploids, but there
are little data on the overall population dynamics of genome change and whether it causes …

Polyploidy has occurred throughout the evolutionary history of all eukaryotes and is
extremely common in plants. Reunification of the evolutionarily divergent genomes in …

Polyploidy is produced by multiplication of a single genome (autopolyploid) or combination
of two or more divergent genomes (allopolyploid). The available data obtained from the …

An unintended consequence of global change is an increase in opportunities for
hybridization among previously isolated lineages. Here we illustrate how global change can …

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 …
