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 …

We have witnessed an explosion in our understanding of the evolution and structure of plant
genomes in recent years. Here, we highlight three important emergent realizations:(1) that …

Multiple cotton genomes (diploid and tetraploid) have been assembled. However, genomic
variations between cultivars of allotetraploid upland cotton (Gossypium hirsutum L.), the …

(novel expression domain or protein function)(the latter two illustrated in Fig. 1). Even more
varied yet poorly understood is the gamut of short-term evolutionary responses to polyploidy …

Duplication is a prominent feature of plant genomic architecture. This has led many
researchers to speculate that gene duplication may have played an important role in the …

Wheat was domesticated about 10,000 years ago and has since spread worldwide to
become one of the major crops. Its adaptability to diverse environments and end uses is …

Polyploidization, the addition of a complete set of chromosomes to the genome, represents
one of the most dramatic mutations known to occur. Nevertheless, polyploidy is well …

Each mode of gene duplication (tandem, tetraploid, segmental, transpositional) retains
genes in a biased manner. A reciprocal relationship exists between plant genes retained …

There is now mounting evidence that heritable variation in ecologically relevant traits can be
generated through a suite of epigenetic mechanisms, even in the absence of genetic …

Polyploidy, or whole-genome duplication (WGD), is an important genomic feature for all
eukaryotes, especially many plants and some animals. The common occurrence of …
