It has long been recognized that hybridization and polyploidy are prominent processes in
plant evolution. Although classically recognized as significant in speciation and adaptation …

Polyploidy, the multiplication of chromosome sets above the diploid state, is arguably as
prevalent in plants as any other eukaryotic group. Over the past century, polyploidy has …

Polyploidy has been widely appreciated as an important force in the evolution of plant
genomes, but now it is recognized as a common phenomenon throughout eukaryotic …

Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

Although plant polyploidization is ubiquitous in nature, polyploidy has long been considered
an evolutionary dead end, precluding further species diversification. However, recent …

Arabidopsis is a model system not only for studying numerous aspects of plant biology, but
also for understanding mechanisms of the rapid evolutionary process associated with …

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 …

The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

Autopolyploidy is more common in plants than traditionally assumed, but has received little
attention compared with allopolyploidy. Hence, the advantages and disadvantages of …

Whole-genome duplication (WGD) is a dramatic, common event in plants. Because of the
detrimental effects arising from doubling the entire chromosome set, such as minority …
