Evolutionary genetics of genome merger and doubling in plants. (2008, background): “Genetic buffering may be especially important for surviving the early genomic shock that can immediately follow polyploid formation (26, 48, 78, 79, 94, 99).”
Genome downsizing in polyploid plants (2004, background): “Feldman et al. (1997), Shaked et al. (2001) and Ozkan et al. (2001, 2003) have speculated that the rapid and non-random sequence elimination observed in Triticum–Aegilops polyploids may play an important role in augmenting differentiation between homoeologous chromosomes, providing a physical basis…”

Breeding triploid plants: a review (2016, background): “At least half of the known angiosperm species have experienced polyploidy in their evolutionary history (Hieter & Griffiths 1999; Shaked et al. 2001; Xing et al. 2010).”
Polyploidy and the Evolutionary History of Cotton (2003, background): “These indications of genomic additivity and epigenetic stasis during allopolyploid formation provide a contrast to recent evidence from several model plant allopolyploids, most notably wheat (Feldman et al., 1997; Liu et al., 1998a,b; Ozkan et al., 2001; Shaked et al., 2001) and Brassica (Song et al”
Genome evolution in allotetraploid Nicotiana (2004, background): “It is possible that molecular analyses such as RFLP and AFLP would reveal further genetic change associated with allopolyploidy, as has been demonstrated for synthetic allopolyploids and hybrids of Brassica (Song et al., 1995) and Triticeae (Ozkan et al., 2001; Shaked et al., 2001).”
