Background Intergenomic gene transfer (IGT) between nuclear and organellar genomes is a
common phenomenon during plant evolution. Gossypium is a useful model to evaluate the …

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 …

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

The evolution of genes and genomes after polyploidization has been the subject of
extensive studies in evolutionary biology and plant sciences. While a significant number of …

Within polyploid plant species, it has been demonstrated that homoeologous genes (genes
duplicated by polyploidy) often display dynamic expression patterns. To determine if …

1998 Nature America Inc.• http://genetics. nature. com news & views allowed the timing and
history of the tetraploid event to be reconstructed—analyses of sequence divergence among …

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

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 …

Approximately 90% of Arabidopsis' unique gene content is found in syntenic blocks that
were formed during the most recent whole-genome duplication. Within these blocks, 28.6 …

Modern sugarcane (Saccharum spp.) is the leading sugar crop and a primary energy crop. It
has the highest level of 'vertical'redundancy (2n= 12x= 120) of all polyploid plants studied to …
