Domesticated cotton species provide raw material for the majority of the world's textile
industry. Two independent domestication events have been identified in allopolyploid …

Ancient tetraploidies are found throughout the eukaryotes. After duplication, one copy of
each duplicate gene pair tends to be lost (fractionate). For all studied tetraploidies, the loss …

Allotetraploid cotton (Gossypium) species represents a model system for the study of plant
polyploidy, molecular evolution, and domestication. Here, chromosome-scale genome …

The predictability of evolution is debatable, with recent evidence suggesting that outcomes
may be constrained by gene interaction networks [1]. Whole-genome duplication (WGD; …

After polyploid formation, retention or loss of duplicated genes is not random. Genes with
some functional domains are convergently restored to 'singleton'state after many …

Polyploid formation has played a major role in the evolution of many plant and animal
genomes; however, surprisingly little is known regarding the subsequent evolution of DNA …

With the advent of high-throughput sequencing, the availability of genomic sequence for
comparative genomics is increasing exponentially. Numerous completed plant genome …

Transposable elements (TEs) are drivers of evolution resulting in episodic surges of genetic
innovation and genomic reorganization (Oliver KR, Greene WK. 2009. TEs: powerful …

Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

Polyploidy complicates transcriptional regulation and increases phenotypic diversity in
organisms. The dynamics of genetic regulation of gene expression between coresident …
