Polyploidy is a common mode of evolution in flowering plants. The profound effects of polyploidy on gene expression appear to be caused more by hybridity than by genome doubling. Epigenetic mechanisms underlying genome-wide changes in expression are as yet poorly understood; only methylation has received much study, and its importance varies among polyploids. Genetic diploidization begins with the earliest responses to genome merger and doubling; less is known about chromosomal diploidization… 

Genome Evolution in Plants

The genomes of land plants vary dramatically in size and chromosome number, and ongoing studies are clarifying the processes that shape their composition, structure and function, including polyploidy and horizontal gene transfer.

Natural Pathways to Polyploidy in Plants and Consequences for Genome Reorganization

The last decade highlighted polyploidy as a rampant evolutionary process that triggers drastic genome reorganization, but much remains to be understood about their causes and consequences in both

Fractionization of Polyploid Duplicated Genes: Gene Loss, Expression Divergence, and Epigenetic Regulation in Brassica napus

This chapter introduced generation and loss of duplicated genes in multiple cycles of whole-genome duplication and described expression divergence of duplicates, particularly those homeologous genes.

Duplications and Turnover in Plant Genomes

An overview of how duplication-driven genomic turn-over has influenced the evolution and diversity of plant genomes is provided.

Responses of Transposable Elements to Polyploidy

It is argued that the study of polyploid systems not only offers the opportunity to highlight specific mechanisms controlling the activity of TEs but also the evolutionary impact of TE-induced genome reorganization.

Genomic asymmetry in allopolyploid plants: wheat as a model.

It is suggested that the process of cytological diploidization leading to exclusive intra-genetic meiotic pairing and, consequently, to complete avoidance of inter-genomic recombination, has two contrasting effects: it provides a means for the fixation of positive heterotic inter- genomic interactions and also maintains genomic asymmetry resulting from loss or silencing of genes.

Molecular Tools for Exploring Polyploid Genomes in Plants

The accumulation of knowledge on polyploid formation, maintenance, and divergence at whole-genome and subgenome levels will not only help plant biologists to understand how plants have evolved and diversified, but also assist plant breeders in designing new strategies for crop improvement.

The evolutionary significance of polyploidy

How, once polyploidy has been established, the unique retention profile of duplicated genes following whole-genome duplication might explain key longer-term evolutionary transitions and a general increase in biological complexity is discussed.

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.

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.

There is compelling evidence that changes in DNA sequence, cis- and trans-acting effects, chromatin modifications, RNA-mediated pathways, and regulatory networks modulate differential expression of homoeologous genes and phenotypic variation that may facilitate adaptive evolution in polyploid plants and domestication in crops.

Advances in the study of polyploidy since Plant speciation

Despite the recent advances in the understanding of polyploid evolution, many exciting aspects remain under-investigated, and some of these include the consequences of genetic and genomic changes in naturalpolyploid populations, the physiological and ecological effects of polyPLoidy, and whether recurrent polyploidsy prompts evolution to repeat itself.
