Heterosis, also known as hybrid vigour, is widespread in plants and animals, but the
molecular bases for this phenomenon remain elusive. Recent studies in hybrids and …

Polyploidy (whole‐genome duplication, WGD) is an integral feature of eukaryotic evolution
with two main forms typically recognized, autopolyploidy and allopolyploidy. In plants, a …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

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 has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …

The evolutionary history of nearly all flowering plants includes a polyploidization event.
Homologous genes resulting from allopolyploidy are commonly referred to as 'homoeologs' …

Polyploidy is a common event in plants that involves the acquisition of more than two
complete sets of chromosomes. Allopolyploidy originates from interspecies hybrids while …

Allopolyploidy involves hybridization and duplication of divergent parental genomes and
provides new avenues for gene expression. The expression levels of duplicated genes in …

Background Polyploidy provides new genetic material that facilitates evolutionary novelty,
species adaptation, and crop domestication. Polyploidy often leads to an increase in cell or …

Polyploidy plays an important role in plant diversification and speciation. The ploidy level of
plants is associated with morphological and biochemical characteristics, and its modification …
