What we still don't know about polyploidy
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 …

[HTML][HTML] Rapid Chromosome Evolution in Recently Formed Polyploids in Tragopogon (Asteraceae)
Background Polyploidy, frequently termed “whole genome duplication”, is a major force in
the evolution of many eukaryotes. Indeed, most angiosperm species have undergone at …

Genome downsizing in polyploid plants
IJ Leitch, MD Bennett - Biological journal of the Linnean Society, 2004 - academic.oup.com
All else being equal, polyploids are expected to have larger C-values (amount of DNA in the
unreplicated gametic nucleus) than their diploid progenitors, increasing in direct proportion …

Genomic aspects of research involving polyploid plants
Almost all extant plant species have doubled their genomes at least once in their
evolutionary histories, resulting in polyploidy which provided a rich genomic resource for …

Endopolyploidy in seed plants is differently correlated to systematics, organ, life strategy and genome size
M Barow, A Meister - Plant, Cell & Environment, 2003 - Wiley Online Library
Endopolyploidy is a systemic feature in seed plants. A negative correlation between genome
size and endopolyploidization has been claimed previously, assuming that a minimum …

Methods for studying polyploid diversification and the dead end hypothesis: a reply to Soltis et al. (2014)
The fate of polyploid lineages has been of long-standing interest to evolutionary biologists.
In our previous work (Mayrose et al., 2011a; reviewed in Arrigo & Barker, 2012), we used …

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