The Chromosome Counts Database (CCDB) - a community resource of plant chromosome numbers. (2015, background): “As noted by Otto & Whitton (2000), this pattern can be explained by frequent polyploidization events, because a genome duplication will always result in an even number while other changes in chromosome numbers (e.g. via dysploidy) can lead to both even and odd aFor comparison, the number of taxa in…”
The convergent evolution of aluminium resistance in plants exploits a convenient currency (2010, background): “Therefore, redundancy can benefit the fitness of organisms by facilitating evolutionary experimentation in changing environments (Otto and Whitton 2000).”
Divergent and narrower climatic niches characterize polyploid species of European primroses in Primula sect. Aleuritia (2013, positive): “Additionally, it has been proposed that polyploids should have broader ecological tolerances than their diploid progenitors, because of their increased genetic and biochemical diversity (Levin, 1983; Otto & Whitton, 2000).”
The transcriptional landscape of polyploid wheat (2018, background): “Polyploidy has beenproposed to confer adaptive plasticity, thereby shaping the evolution of plants, fungi, and, to a lesser degree, animals (1, 2).”
Non-Mendelian Phenomena in Allopolyploid Genome Evolution (2002, background): “These subjects have been thoroughly reviewed elsewhere [6-8,27-32] and will not be discussed here.”
Mating Consequences of Polyploid Evolution in Flowering Plants: Current Trends and Insights from Synthetic Polyploids (2008, background): “These shifts in ploidy can have significant effects on morphological, physiological, and life-history traits, owing to direct effects on cell size, cell cycle, and development rate and indirect effects on heterozygosity and adaptive potential (Levin 1983, 2002; Otto and Whitton 2000).”
Polyploidy in Fish and the Teleost Genome Duplication (2012, background): “Several works provide comprehensive lists of known cases of polyploidy in fish (Otto and Whitton 2000; Leggatt and Iwama 2003; Le Comber and Smith 2004; Mable et al. 2011).”
Plants with double genomes might have had a better chance to survive the Cretaceous–Tertiary extinction event (2009, background): “There is ample evidence that gene duplication fuels long-term diversification and evolutionary success through the evolution of novel gene functions (32, 34), but the short-term advantages of polyploidy are less known.”
Functional Divergence of Duplicated Genes Formed by Polyploidy during Arabidopsis Evolution (2004, background): “On the other hand, more and more data indicate that polyploidy and aneuploidy occur frequently in plants (Shoemaker et al., 1996; Gaut and Doebley, 1997; Arabidopsis Genome Initiative, 2000; Otto and Whitton, 2000; Wendel, 2000; Goff et al., 2002; Vandepoele et al., 2003).”
The evolutionary consequences of polyploidy. (2007, methodology): “…of the mutation discounted by the dominance of the mutation when in a single copy, hc. Altogether, the mean fitness of a population is expected to rise at a rate equal to DWc = (ncN)(2hcs)s (assuming sexual reproduction and multisomic inheritance, see Otto and Whitton, 2000 for other cases).”
In vitro induction of tetraploids in Phlox subulata L. (2007, background): “It has been estimated that up 70% of land plants and 95% of ferns have some polyploidy in their evolutionary history (Leitch and Bennett 1997; Otto and Whitton 2000).”
Genome-size evolution in fishes (2004, background): “Relative to the marine environment, where few barriers limit gene flow, the freshwater environment is highly dissected, providing more opportunities for population isolation, a factor that may enhance opportunities for the synthesis of polyploids (Otto and Whitton 2000).”
