The role of hybridization in plant speciation. (2009, background): “Polyploidy clearly plays a major role in modifying global patterns of gene expression (2, 73, 138, 197) and may be a major source of developmental novelty in polyploid systems (49).”
The evolutionary significance of ancient genome duplications (2009, background): “In allopolyploids and autopolyploids, increased heterozygosity can lead to increased variation in gene expression and in regulatory wirin”
The Genomes of Oryza sativa: A History of Duplications (2005, background): “In plants, the existence issue is not disputed, as polyploidy is common [48,49,50,51,52,53], but even with complete genome sequence, many details remain obscure.”
The more the better? The role of polyploidy in facilitating plant invasions. (2012, background): “Epigenetic effects include gene expression regulation, changes in imprinting genes, defence against viral infection and the repression of transposable elements (Osborn et al., 2003).”
Mitotic chromosome doubling of plant tissues in vitro (2010, background): “Moreover, polyploids have an overall increased gene expression level compared to diploids, which could result in an affected dosage-regulated expression (Osborn et al. 2003).”
Genomic Changes in Resynthesized Brassica napus and Their Effect on Gene Expression and Phenotype[W][OA] (2007, background): “In fact, studies in natural B. napus have reported HNRTs with phenotypic effects on seed yield (Osborn et al., 2003a) and Sclerotinia resistance (Zhao et al., 2006).”
The role of RNA interference in heterochromatic silencing (2004, background): “If siRNA pools are largely maternal, cytoplasmic siRNA could contribute to chromosome loss and transposon activation (hybrid dysgenesis) if they fail to match paternal chromosome sequence”
Flowering time divergence and genomic rearrangements in resynthesized Brassica polyploids (Brassicaceae) (2004, background): “…and/or resynthesized B. napus that involve the © 2004 The Linnean Society of London, Biological Journal of the Linnean Society, 2004, 82, 675–688 transposition of segments between homoeologous chromosomes (Parkin et al., 1995; Sharpe et al., 1995; Osborn et al., 2003a; Quijada, 2003; Udall, 2003).”
The “Polyploid Hop”: Shifting Challenges and Opportunities Over the Evolutionary Lifespan of Genome Duplications (2018, background): “Despite this prevalence, however, WGD is no easy victory: the presence of an extra set of chromosomes creates numerous biological challenges ranging from chromosome mis-segregation to altered gene expression, changes in cell size or in intracellular physiology (Ramsey and Schemske, 2002; Osborn et a”

Genetic and epigenetic mechanisms for gene expression and phenotypic variation in plant polyploids. (2007, background): “Several mechanisms may affect the fate of orthologous and homoeologous genes in polyploids (25,29,76,79,86,95,111,132,149) (Figure 2).”
Hybridization, polyploidy and invasion: lessons from Spartina (Poaceae) (2009, background): “During the last decade, various studies have revealed that these events have critical impact at the molecular, cellular and (organismal) phenotypic levels (reviewed in Comai 2000; Wendel 2000; Osborn et al. 2003; Riddle and Birchler 2003; Adams and Wendel 2005; Albertin et al. 2006; Chen 2007).”
