摘要： Chromosome rearrangement plays an important role in plant evolution, being ubiquitous after polyploidization. Genomic changes in resynthesized and natural polyploids are common consequences of polyploidization across a wide range of species (Wendel 2000; Chen 2007; Hegarty and Hiscock 2005; Leitch and Leitch 2008; Soltis and Soltis 2009; Gaeta and Pires 2010; Wang et al. 2012; Lavania et al. 2012). Newly formed polyploid hybrids are not true species unless they are genetically, ecologically or reproductively isolated from their parental taxa (Ungerer et al. 1998). It is assumed that chromosome rearrangements facilitate the establishment of newly formed polyploid as successful species (Wendel et al. 1995; Feldman et al. 1997; Hegarty and Hiscock 2008).
