Polyploidy has been hypothesized to be both an evolutionary dead-end and a source for
evolutionary innovation and species diversification. Although polyploid organisms …

Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

Upland cotton is a model for polyploid crop domestication and transgenic improvement.
Here we sequenced the allotetraploid Gossypium hirsutum L. acc. TM-1 genome by …

Main conclusion This article provides an up-to-date review concerning from basic issues of
polyploidy to aspects regarding the relevance and role of both natural and artificial …

Polyploidy, defined as the coexistence of three or more complete sets of chromosomes in an
organism's cells, is considered as a pivotal moving force in the evolutionary history of …

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 has long been recognized as a fundamental evolutionary process in plants
but, until recently, our understanding of its phylogenetic distribution and biological …

The Brassica genus encompasses three diploid and three allopolyploid genomes, but a
clear understanding of the evolution of agriculturally important traits via polyploidy is lacking …

Hybridization has played an important role in the evolution of many lineages. With the
growing availability of genomic tools and advancements in genomic analyses, it is becoming …

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 …
