Allopolyploidy has been a prominent mode of speciation and a recurrent process during
plant evolution and has contributed greatly to the large number of duplicated genes in plant …

Background Millennia of directional human selection has reshaped the genomic architecture
of cultivated cotton relative to wild counterparts, but we have limited understanding of the …

Large-scale genomic surveys of crop germplasm are important for understanding the
genetic architecture of favorable traits. The genomic basis of geographic differentiation and …

Hybridization and polyploidization are prominent processes in plant evolution. Hybrids and
allopolyploids typically exhibit radically altered gene expression patterns relative to their …

Hybridization and polyploidy have been considered as significant evolutionary forces in
adaptation and speciation, especially among plants. Interspecific gene flow generates novel …

Polyploidy is now recognized as a characteristic feature of all angiosperm genomes (Jiao et
al., 2011), and remains an important speciation process today (Wendel, 2000; Comai, 2005; …

Comparative population genomics offers an excellent opportunity for unraveling the genetic
history of crop domestication. Upland cotton (Gossypium hirsutum) has long been an …

Cotton is not only the world's most important natural fiber crop, but it is also an ideal system
in which to study genome evolution, polyploidization, and cell elongation. With the assembly …

Polyploidy is a major force in plant evolution and speciation. In newly formed allopolyploids,
pairing between related chromosomes from different subgenomes (homoeologous …

Polyploidy or whole genome duplication (WGD) occurs throughout the evolutionary history
of many plants and some animals, including crops such as wheat, cotton, and sugarcane …
