The more the better? The role of polyploidy in facilitating plant invasions. (2012, background): “Nevertheless, while shifts towards apomixis are common in polyploids (Norrmann et al., 1989; Quarin et al., 1998, 2001; Naumova et al., 1999; Krahulcová and Rotreklová, 2010), some polyploid offspring can remain completely sexual (Stebbins, 1950; Hashemi et al., 1989; Ayres et al., 2008).”
Coevolution of apomixis and genome size within the genus Hypericum (2003, background): “Whether polyploidy may also cause apomixis in Hypericum, as was suggested for Paspalum notatum ( Quarin et al. 2001 ), needs further investigation.”
Apomixis: Developmental Characteristics and Genetics (2006, background): “Using cDNA clones mapped in rice on a segregating population of Paspalum simplex, apospory was localized to a region of the genome syntenic with the long-arm telomeric region of rice chromosome 12 (Pupilli et al., 2001).”
