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

Chromosome evolution has been demonstrated to have profound effects on diversification
rates and speciation in angiosperms. While polyploidy has predated some major radiations …

Genome doubling (polyploidy) has been and continues to be a pervasive force in plant
evolution. Modern plant genomes harbor evidence of multiple rounds of past …

Polyploidy is an evolutionary process whereby two or more genomes are brought together
into the same nucleus, usually by hybridization followed by chromosome doubling. As a …

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 …

Polyploidy, the genome wide duplication of chromosome number, is a key feature in
eukaryote evolution. Polyploidy exists in diverse groups including animals, fungi, and …

Polyploid cells have genomes that contain multiples of the typical diploid chromosome
number and are found in many different organisms. Studies in a variety of animal and plant …

Understanding the evolutionary plasticity of the genome requires a global, comparative
approach in which genetic events are considered both in a phylogenetic framework and with …

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 …

Genomic sequencing projects have revealed the productivity of processes duplicating genes
or entire chromosome segments. Substantial proportions of the yeast, Arabidopsis and …
