Allopolyploidization, resulting in divergent genomes in the same cell, is believed to trigger a
“genome shock”, leading to broad genetic and epigenetic changes. However, little is …

Understanding the composition, evolution, and function of the Gossypium hirsutum (cotton)
genome is complicated by the joint presence of two genomes in its nucleus (AT and DT …

Background Despite remarkable advances in our knowledge of epigenetically mediated
transcriptional programming of cell differentiation in plants, little is known about chromatin …

Allopolyploidy is an evolutionary and mechanistically intriguing process, in that it entails the
reconciliation of two or more sets of diverged genomes and regulatory interactions. In this …

Polyploidy plays a major role in genome evolution, which corresponds to environmental
changes over millions of years. The mechanisms of genome evolution, particularly during …

Histone modifications regulate gene expression in eukaryotes, but their roles in gene
expression changes in interspecific hybrids or allotetraploids are poorly understood. Histone …

The formation of polyploids significantly increases the complexity of transcriptional
regulation, which is expected to be reflected in sophisticated higher-order chromatin …

Allopolyploidization is accompanied by changes in gene expression that are thought to
contribute to phenotypic diversification. Here we describe global changes in the single …

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

Allopolyploidy is an important process during plant evolution that results in the reunion of
two divergent genomes into a common nucleus. Many of the immediate as well as longer …
