Cultivated strawberry (Fragaria× ananassa), a perennial herb belonging to the family
Rosaceae, is a complex octoploid with high heterozygosity at most loci. However, there is no …

Introduction The simultaneous improvement of fiber quality and yield for cotton is strongly
limited by the narrow genetic backgrounds of Gossypium hirsutum (Gh) and the negative …

Some interspecific plant hybrids show unequal transmission of chromosomes from parental
genomes to the successive generations. It has been suggested that this is due to a …

Genome or genomic dominance (GD) is a phenomenon observed in hybrids when one
parental genome becomes dominant over the other. It is manifested by the replacement of …

Polyploids are common and have a wide geographical distribution and environmental
adaptability. Allopolyploidy may lead to the activation of transposable elements (TE) …

Restoring cytonuclear stoichiometry is necessary after whole‐genome duplication (WGD)
and interspecific/intergeneric hybridization in plants. We investigated this phenomenon in …

Polyploidy is an important evolutionary process throughout eukaryotes, particularly in
flowering plants. Duplicated gene pairs (homoeologs) in allopolyploids provide additional …

Genome dominance is a phenomenon in wide hybrids when one of the parental genomes
becomes “dominant,” while the other genome turns to be “submissive.” This dominance may …

Allopolyploidization often leads to disruptive conflicts among more than two sets of
subgenomes, leading to genomic modifications and changes in gene expression. Although …

Interspecific hybridization drives the evolution of angiosperms and can be used to introduce
novel alleles for important traits or to activate heterosis in crop breeding. Hybridization …
