Polyploidy has been hypothesized to be both an evolutionary dead-end and a source for
evolutionary innovation and species diversification. Although polyploid organisms …

Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Polyploidy, defined as the coexistence of three or more complete sets of chromosomes in an
organism's cells, is considered as a pivotal moving force in the evolutionary history of …

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 …

Whole-genome duplication (WGD), which leads to polyploidy, is implicated in adaptation
and speciation. But what are the immediate effects of WGD and how do newly polyploid …

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

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 …

During the past decade there has been a tremendous resurgence of interest in polyploidy
that has in large part been stimulated by the development of increasingly powerful genetic …

Polyploidy is a common mode of speciation that can have far‐reaching consequences for
plant ecology and evolution. Because polyploidy can induce an array of phenotypic …

Bread wheat (Triticum aestivum L.) is an allopolyploid species containing three ancestral
genomes. Therefore, three homoeologous copies exist for the majority of genes in the wheat …
