Whole genome duplication (polyploidy) represents a primary mechanism of sympatric
speciation, especially in plants where it is particularly prevalent. In this chapter, we focus on …

Background Allopolyploid speciation requires rapid evolutionary reconciliation of two
diverged genomes and gene regulatory networks. Here we describe global patterns of gene …

Elucidating the causes and consequences of polyploidy (whole-genome duplication; WGD)
is arguably central to understanding the evolution of most eukaryotic lineages. However …

Genome duplication is thought to be central to the evolution of morphological complexity,
and some polyploids enjoy a variety of capabilities that transgress those of their diploid …

We present an overview of the cotton genus (Gossypium) as a model for the study of
polyploidy. A synopsis of the origin and evolution of polyploid cotton is provided, offering an …

Recent work has demonstrated that allopolyploid speciation in plants may be associated
with non-Mendelian genomic changes in the early generations following polyploid …

Recent advances in the genomics of polyploid species answer some of the long-standing
questions about the role of polyploidy in crop species. Here, we summarize the current …

A complicating factor in analyzing allopolyploid genomes is the possibility of physical
interactions between homoeologous chromosomes during meiosis, resulting in either …

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 …

Background Polyploidy has played a prominent role in shaping the genomic architecture of
the angiosperms. Through allopolyploidization, several modern Gossypium (cotton) species …
