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

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

Evolutionary consequences of autopolyploidy
Autopolyploidy is more common in plants than traditionally assumed, but has received little
attention compared with allopolyploidy. Hence, the advantages and disadvantages of …

Mixed-ploidy species: progress and opportunities in polyploid research
Mixed-ploidy species harbor a unique form of genomic and phenotypic variation that
influences ecological interactions, facilitates genetic divergence, and offers insights into the …

The role of genetic and genomic attributes in the success of polyploids
In 1950, G. Ledyard Stebbins devoted two chapters of his book Variation and Evolution in
Plants (Columbia Univ. Press, New York) to polyploidy, one on occurrence and nature and …

Gametes with the somatic chromosome number: mechanisms of their formation and role in the evolution of autopolyploid plants
summary The production of 2n gametes in plants, ie gametes with a somatic chromosome
number, is considered to be the dominant process involved in the origin of polyploid plants …
