Most eukaryotes have genomes that exhibit high levels of gene redundancy, much of which seems to have arisen from one or more cycles of genome doubling. Polyploidy has been particularly prominent during flowering plant evolution, yielding duplicated genes (homoeologs) whose expression may be retained or lost either as an immediate consequence of polyploidization or on an evolutionary timescale. Expression of 40 homoeologous gene pairs was assayed by cDNA-single-stranded conformation…

Organ-Specific Silencing of Duplicated Genes in a Newly Synthesized Cotton Allotetraploid

A detailed portrayal of gene silencing events that can occur following allopolyploidization is provided and epigenetic causal factors are suggested.

It has become clear that hybridization has a much greater effect than chromosome doubling on gene expression in allopolyploids, and diploid and triploid F(1) hybrids can show alterations of expression levels compared with their parents.

Homoeologous gene silencing in hexaploid wheat.

It is suggested that a substantial proportion of transcriptional silencing within single-copy genes within groups 1, 2, 3 and 7 of wheat is effected by an epigenetic mechanism, and that this form of genetic variation may be a significant player in the determination of phenotypic diversity in breeding populations.

The origins and forms of polyploidy are reviewed, transcriptome divergence between the progenitors and in the newly formed allopolyploids are shown and models for transcriptional regulation, chromatin modification and RNA-mediated pathways in establishing locus-specific expression of orthologous and homoeologous genes are proposed.

Evolution by polyploidy and gene regulation in Anura.

The high genetic variability of autotetraploid anurans is a result of tetrasomic expression, based on studies of isozymes and other proteins, and Epigenetic mechanisms mediate the reduced expression or silencing of redundant copies of genes in the regulation of gene expression of these tetraploids.

The fate of duplicated genes in a polyploid plant genome.

It is found that transcription factors and ribosomal protein genes were differentially expressed in many tissues, suggesting that the main consequence of polyploidy in soybean may be at the regulatory level.

Reciprocal Silencing, Transcriptional Bias and Functional Divergence of Homeologs in Polyploid Cotton (Gossypium)

This study represents the first characterization of transcriptional neofunctionalization in an allopolyploid, and provides a novel temporal perspective on expression evolution of duplicate genomes and add to the understanding of the importance of polyploidy in plants.

Partitioned expression of duplicated genes during development and evolution of a single cell in a polyploid plant

Investigation of the expression of thousands of pairs of homoeologs during the development of a single plant cell of allopolyploid cotton suggests that domestication may increase expression bias in fibers toward the D genome, potentially implicating D-genome recruitment under human selection during domestication.

Gene loss and silencing in Tragopogon miscellus (Asteraceae): comparison of natural and synthetic allotetraploids

Hphazard loss and silencing of homoeologues are shown, occurring within decades of polyploid formation in T. miscellus, but not in the initial generation.



Protein-coding genes are epigenetically regulated in Arabidopsis polyploids.

Ten genes that are silenced from either A. thaliana or C. arenosa origin in Arabidopsis suecica are identified, suggesting epigenetic regulation is involved in the expression of orthologous genes in polyploid genomes.

Duplicated genes evolve independently after polyploid formation in cotton.

It is indicated that most duplicated genes in allopolyploid cotton evolve independently of each other and at the same rate as those of their diploid progenitors.

Phenotypic Instability and Rapid Gene Silencing in Newly Formed Arabidopsis Allotetraploids

Evidence that gene silencing accompanies allopolyploidization opens new avenues to this area of research.

Evolution and expression of MYB genes in diploid and polyploid cotton

Spatial and temporal expression patterns appear to have been evolutionarily conserved, both during divergence of the diploid parents of allopolyploid cotton and following polyploid formation, but the duplicated copies of MYB1 in the tetraploid are not expressed at equal levels or equivalently in all organs, suggesting possible functional differentiation.


A very recent origin for both tetraploids is suggested by the near identity of several of their PgiC genes to their corresponding diploid orthologues and the absence of any acceleration in mutation rates.

Genome evolution in polyploids

Processes and mechanisms of gene and genome evolution in polyploids are reviewed, including the role of transposable elements in structural and regulatory gene evolution; processes and significance of epigenetic silencing; underlying controls of chromosome pairing and mechanisms and functional significance of rapid genome changes are reviewed.

In Brassica napus, rRNA genes silenced in vegetative tissues were found to be expressed in all floral organs, arguing against the hypothesis that passage through meiosis is needed to reactivate suppressed genes.

Gene loss, silencing and activation in a newly synthesized wheat allotetraploid.

Findings show that wide hybridization and chromosome doubling affect gene expression via genetic and epigenetic alterations immediately upon allopolyploid formation and contribute to the genetic diploidization of newly formed allopoly Ploidy in wheat.

Rapid genome change in synthetic polyploids of Brassica and its implications for polyploid evolution.

It is demonstrated that polyploid species can generate extensive genetic diversity in a short period of time and genetic divergence among the derivatives of synthetic polyploids was evident from variation in genome composition and phenotypes.

A change of ploidy can modify epigenetic silencing.

An increased number of chromosomes can result in a new type of epigenetic gene inactivation, creating differences in gene expression patterns, and the possible impact for genetic diploidization in the light of widespread, naturally occurring polyploidy and polysomaty in plants.
