Hybridization is a creative evolutionary force, increasing genomic diversity and facilitating
adaptation and even speciation. Hybrids often face significant challenges to establishment …

Allopolyploidy is a prominent mode of speciation in higher plants. Due to the coexistence of
closely related genomes, a successful allopolyploid must have the ability to invoke and …

Recent studies have shown that one of the parental subgenomes in ancient polyploids is
generally more dominant, having retained more genes and being more highly expressed, a …

▪ Abstract Here we review the biology of early generation neopolyploids and discuss the
profound changes that accompany their formation. Newly formed auto-and allopolyploids …

Perhaps all flowering plants have experienced one or more episodes of polyploidization at
some time in their evolutionary history. Recent evidence indicates that this genome doubling …

The reduction in genetic diversity in polyploid lineages, formed from whole-genome
duplication of a few individuals, can affect their long-term evolutionary potential. Because …

Background Polyploidy or whole-genome duplication is now recognized as being present in
almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most …

Apomicts that produce unreduced parthenogenetic eggs are generally polyploid and occur
in at least 33 of 460 families of angiosperms. Embryo sacs of these apomicts form …

The prevalence of polyploidy among flowering plants is surprising given the hurdles
impeding the establishment and persistence of novel polyploid lineages. In the absence of …
