An allopolyploidization event formed allotetraploid Gossypium species from an A‐genome
diploid species and a D‐genome diploid species. To explore the responses of transposable …

The genomes and annotated genes of allotetraploid cotton Gossypium hirsutum have been
extensively studied in recent years. However, the expression, regulation, and evolution of …

Transposable elements (TEs) are a major component of plant genomes. It is of particular
interest to explore the potential activation of TE proliferation, especially in hybrids and …

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 …

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

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

Stabilization of transposable element (TE) copy number involves the biosynthesis of short
silencing RNAs (siRNAs) and further initialization of siRNA‐mediated TE silencing. To gain …

Transposable elements contribute significantly to plant genome evolution in myriad ways,
ranging from local insertional mutations to global effects exerted on genome size through …

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 …

Background Interspecific hybridization and whole genome duplication are driving forces of
genomic and organism diversification. But the effect of interspecific hybridization and whole …
