▪ Abstract Here we review the biology of early generation neopolyploids and discuss the profound changes that accompany their formation. Newly formed auto- and allopolyploids exhibit considerable meiotic complexity, including multivalent pairing, multisomic inheritance, and the production of unbalanced gametes. The cytogenetic behavior of allopolyploids and autopolyploids differ statistically, but are more similar than commonly believed. The progeny of neopolyploids include a high frequency of…

Meiosis in Polyploids and Implications for Genetic Mapping: A Review

This review describes in detail the meiotic process in auto- and allopolyploids from the onset of prophase I through pairing, recombination, and bivalent formation, highlighting recent findings on the genetic control and mode of action of specific proteins that lead to diploid-like meiosis behavior in polyploid species.

Meiosis in Polyploid Plants

A more relaxed control of pairing and segregation in polyploids might be an important contribution to evolution and adaptation potential, especially under drastic or frequent changes in environmental conditions.

Meiosis in autopolyploid and allopolyploid Arabidopsis.

Evolutionary consequences of autopolyploidy.

It is hypothesized that polysomic inheritance may provide a short-term evolutionary advantage for autopolyploids compared to diploid relatives when environmental change enforces range shifts, and should possess increased genome flexibility, allowing them to adapt and persist across heterogeneous landscapes in the long run.

Genomic and Meiotic Changes Accompanying Polyploidization

An overview of genomic changes and transcriptomic modifications that particularly occur at the early stages of allopolyploid formation is provided.

Speciation Success of Polyploid Plants Closely Relates to the Regulation of Meiotic Recombination

The consequences ofpolyploid formation pathways, meiotic behavior and recombination regulation on the speciation success and maintenance of polyploid species are discussed.

The challenge of evolving stable polyploidy: could an increase in “crossover interference distance” play a central role?

It is proposed that a critical feature in the evolution of these more effective chiasma patterns is an increase in the effective distance of meiotic crossover interference, which plays a central role in crossover positioning.

Lessons from Natural and Artificial Polyploids in Higher Plants

An overview of lessons learnt from studies of natural and artificial polyploids, and from comparisons between the 2, covering basic cellular and metabolic consequences through to alterations in epigenetic gene regulation, together with 2 in-depth case studies in Senecio and Glycine are presented.

Rapid cytological diploidization in newly formed allopolyploids of the wheat (Aegilops-Triticum) group.

Findings support the conclusion that rapid elimination of low-copy noncoding DNA sequences from one genome of a newly formed allopolyploid, different sequences from different genomes, is an efficient way to quickly augment the divergence between homoeologous chromosomes and thus bring about cytological diploidization.



Polyploidy and Novelty in Flowering Plants

Evidence is presented herein from biochemical, physiological, developmental, and genetical sources which indicates that the nucleotypic effects of chromosome doubling are not necessarily negative, and indeed chromosome doubling may "propel" a population in to a new adaptive sphere, and render it capable of occupying habitats beyond the limits of its diploid progenitor.

The Effect of Structural Heterozygosity on the Degree of Preferential Pairing in Allotetraploids of Zea.

The finding that the natural allotetraploid Nicotiana tabacum has fewer duplicate factors than its newly synthesized counterpart ( CLAUSEN 1941 ) supports STEBBINS’ idea that large chromosome rearrangements participate in the process of diploidization.


The results indicate that the triploid bridge pathway can contribute significantly to autopolyploids formation regardless of the mating system, and to allopolyploid formation in outcrossing taxa.


This paper is based on a lecture presented at the symposium on "Frontiers of Plant Genetics" sponsored by the Genetics Section of the Botanical Society of America and held at Indiana University in August, 1981 and on data from various sources show that the generally held dogma that the inability of chromosomes to pair in F1 hybrids is due to considerable genetic divergence is not true.

Physiology of polyploids.

Future work on the physiology of autopolyploid plants should be directed towards: the investigation of more representative experimental systems that should include genetically homogeneous and heterogeneous species of both wild and cultivated plants; and diploid-polyploid comparisons on the level of isolated tissues and cells, in addition to the whole plant.


Several recent hypotheses have proposed that the wide capabilities of allopolyploids are a direct biochemical consequence of their possession of two divergent diploid genomes which provides them with a multiplicity of enzymes relative to both diploids parents as well as a high proportion of novel enzymes.

Polyploid incidence and evolution.

New estimates for the incidence of polyploidy in ferns and flowering plants are presented based on a simple model describing transitions between odd and even base chromosome numbers, and it is indicated that ploidy changes may represent from 2 to 4% of speciation events in flowering plants and 7% in f Ferns.

Insight into genome function gained from the study of allopolyploidy may be applicable to hybrids of any type and may even elucidate positive interactions, such as those responsible for hybrid vigor.

Molecular data and the dynamic nature of polyploidy

Molecular data strongly suggest that recurrent formation of polyploid species is the rule, rather than the exception, and that multiple origins were found to be frequent on a local geographic scale, as well as during a short span of time.
