Polyploidy is a major force in plant evolution and speciation. In newly formed allopolyploids,
pairing between related chromosomes from different subgenomes (homoeologous …

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

Background The sharp increase of plant genome and transcriptome data provide valuable
resources to investigate evolutionary consequences of gene duplication in a range of taxa …

Allopolyploid speciation is widespread in plants, yet the molecular requirements for
successful orchestration of coordinated gene expression for two divergent and reunited …

The prevalence and recurrence of polyploidization in plant species make it one of the most
important evolutionary events in plants, and as a result, polyploidization is an extensively …

Polyploidy in populations of well-differentiated plant species is now widely recognized (1, 2).
Most reports, however, are limited to a few individuals from one or several populations and …

Precise chromosome segregation is vital for polyploid speciation. Here, we highlight recent
findings that revitalize the old question of the genetic control of diploid‐like meiosis …

Gene duplications provide evolutionary potentials for generating novel functions, while
polyploidization or whole genome duplication (WGD) doubles the chromosomes initially and …

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 …

Abstract Background and Aims Polyploidy is arguably the single most important genetic
mechanism in plant speciation and diversification. It has been repeatedly suggested that …
