Newly formed polyploids often show extensive meiotic defects, resulting in aneuploid
gametes, and thus reduced fertility. However, while many neopolyploids are meiotically …

Whole-genome duplication resulting from polyploidy is ubiquitous in the evolutionary history
of plant species. Yet, polyploids must overcome the meiotic challenge of pairing …

Polyploidy, which arises from genome duplication, has occurred throughout the history of
eukaryotes, though it is especially common in plants. The resulting increased size …

Polyploidization is a widespread phenomenon, especially in flowering plants that have all
undergone at least one event of whole genome duplication during their evolutionary history …

Formation of polyploid organisms by fertilization of unreduced gametes in meiotic mutants is
believed to be a common phenomenon in species evolution. However, not well understood …

Polyploid genomes evolve and follow a series of dynamic transfigurations along with
adaptation and speciation. The initial formation of a new polyploid individual within a diploid …

Polyploidization, a widespread phenomenon among plants, is considered a major
speciation mechanism. Polyploid plants have a high degree of immediate post-zygotic …

Polyploidy has played a major role in the evolution of higher plants. Precise control of
chromosome pairing is vital for conferring meiotic regularity, and hence reproductive stability …

Allopolyploidy, the joining of two parental genomes in a polyploid organism with diploid
meiosis, is an important mechanism of reticulate evolution. While many successful long …

▪ Abstract Polyploidy is widely acknowledged as a major mechanism of adaptation and
speciation in plants. The stages in polyploid evolution include frequent fertility bottlenecks …
