Polyploidy and interspecific hybridization: partners for adaptation, speciation and evolution in plants
Background Polyploidy or whole-genome duplication is now recognized as being present in
almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most …

Hybridization and speciation
Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

Genetic contribution of paleopolyploidy to adaptive evolution in angiosperms
Ancient whole-genome duplications (WGDs or polyploidy) are prevalent in plants, and some
WGDs occurred during the timing of severe global environmental changes. It has been …

The role of hybridization in plant speciation
The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

The evolutionary significance of ancient genome duplications
Many organisms are currently polyploid, or have a polyploid ancestry and now have
secondarily'diploidized'genomes. This finding is surprising because retained whole-genome …

Widespread whole genome duplications contribute to genome complexity and species diversity in angiosperms
Gene duplications provide evolutionary potentials for generating novel functions, while
polyploidization or whole genome duplication (WGD) doubles the chromosomes initially and …

Bias in plant gene content following different sorts of duplication: tandem, whole-genome, segmental, or by transposition
M Freeling - Annual review of plant biology, 2009 - annualreviews.org
Each mode of gene duplication (tandem, tetraploid, segmental, transpositional) retains
genes in a biased manner. A reciprocal relationship exists between plant genes retained …

Gossypium barbadense genome sequence provides insight into the evolution of extra-long staple fiber and specialized metabolites
Of the two cultivated species of allopolyploid cotton, Gossypium barbadense produces extra-
long fibers for the production of superior textiles. We sequenced its genome (AD) 2 and …
