Although major advances have been made during the past 20 years in our understanding of
the genetic and genomic consequences of polyploidy, our knowledge of polyploidy and the …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Polyploidy is an evolutionary innovation, providing extra sets of genetic material for
phenotypic variation and adaptation. It is predicted that changes of gene expression by …

Autopolyploidy and allopolyploidy are common in many plants and some animals. Rapid
changes in genomic composition and gene expression have been observed in both …

Most eukaryotes have an evolutionary history of repeated polyploidization followed by
fractionation (or diploidization; Makino and McLysaght, 2010; Jiao et al., 2011). The …

Polyploidy has played an important role in promoting plant evolution through genomic
merging and doubling. Although genomic and transcriptomic changes have been observed …

Almost all extant plant species have doubled their genomes at least once in their
evolutionary histories, resulting in polyploidy which provided a rich genomic resource for …

Heterosis is characterized by higher seed yields, plant biomass or other traits in
heterozygotes or hybrids compared with their genetically divergent parents, which are often …

Polyploidy is a very common phenomenon in the plant kingdom, where even diploid species
are often described as paleopolyploids. The polyploid condition may bring about several …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …
