Allotetraploid plant species originate when the genomes of diploid species are brought
together in hybrids and then duplicated, a process apparently initiated by fertilization …

Polyploidy, or the presence of two or more diploid parental genome sets within an organism,
is found to an amazing degree in higher plants. In addition, many plant species traditionally …

Polyploidy is a major creative force in plant evolution, from ferns to flowering plants.
Estimates suggest that B70% of flowering plants have undergone at least one whole …

Polyploidization has occurred often in the evolutionary history of eukaryotes, yet we are only
now learning about the genetic and epigenetic events that occur in newly formed polyploids …

Genome doubling, or polyploidy, is a major factor accounting for duplicate genes found in
most eukaryotic genomes. Polyploidy has considerable effects on duplicate gene …

Of the many processes that generate gene duplications, polyploidy is unique in that entire
genomes are duplicated. This process has been important in the evolution of many …

Most eukaryotes have a history of whole-genome multiplication events followed by a
progressive return to a more diploid state. The initial state of polyploidization, in which more …

Publisher Summary This chapter provides a discussion of recent advancements, in context
to plant polyploidy. Polyploidy plays a very important role in plant evolution. Major recent …

Recent work has demonstrated that allopolyploid speciation in plants may be associated
