• The more the better? The role of polyploidy in facilitating plant invasions. (2012, background): “The total DNA amount (C-value) rises with increased ploidy, but the increase is often not proportional, resulting in the decline of Cx-values (i.e. genome downsizing; Leitch and Bennett, 2004).”
• Polyploidy, the Nucleotype, and Novelty: The Impact of Genome Doubling on the Biology of the Cell (2019, background): “Although much of the reduction in genome size could be due to natural selection operating over time as part of the diploidization process (e.g., Dodsworth et al. 2016), Leitch and Bennett (2004) also note that reduction could be an immediate effect of recombination.”
• Genomic Consequences of Outcrossing and Selfing in Plants (2008, background): “A review of the literature generally supports this model and suggests that genomic imprinting driven by sexual conflict has declined in selfing species (Brandvain and Haig 2005).”
• The “Polyploid Hop”: Shifting Challenges and Opportunities Over the Evolutionary Lifespan of Genome Duplications (2018, background): “A similar reasoning holds with genome sizes (Wendel, 2015): thus it is apparent that past polyploidization events were followed by massive genome downsizing, both in chromosome numbers and in absolute size (Leitch and Bennett, 2004; Leitch and Leitch, 2008).”
• The largest eukaryotic genome of them all (2010, background): “Episodes of polyploidy are frequent in plants (Soltis & Soltis, 2000; Wendel, 2000; Cui et al., 2006), leading to genome reorganization at functional and structural levels that occurs during and after genome duplication, some of them involving genome size changes (Leitch & Bennett, 2004).”
• Autopolyploidy in angiosperms: Have we grossly underestimated the number of species? (2007, positive): “…effects of plant polyploidy (reviewed in Thompson & al., 1997, 2004), and the genetic, epigenetic, chromosomal, and genomic consequences of polyploidization (e.g., Liu & Wendel, 2003; Bowers & al., 2003; Osborn & al., 2003; Leitch & Bennett, 2004; Adams & Wendel, 2005; Rapp & Wendel, 2005).”
