AbstractAncient whole-genome duplications (WGDs) are believed to facilitate novelty and adaptation by providing the raw fuel for new genes. However, it is unclear how recent WGDs may contribute to evolvability within recent polyploids. Hybridization accompanying some WGDs may combine divergent gene content among diploid species.

Introduction Upland cotton (Gossypium hirsutum L.) is the world's top renewable textile fibre, supporting a multibillion-dollar industry with a global production of 120.2 million bales of cotton (~26 million metric tonnes). It is a major economically important crop for the U.S. and for Arizona, where upland cotton is planted on ∼50 000 ha, mainly in the semi-arid environment of the low desert using surface irrigation to complement limited precipitation.

AbstractTeleost fishes, which are the largest and most diverse group of living vertebrates, have a rich history of ancient and recent polyploidy. Previous studies of allotetraploid common carp and goldfish (cyprinids) reported a dominant subgenome, which is more expressed and exhibits biased gene retention. However, the underlying mechanisms contributing to observed ‘subgenome dominance’ remains poorly understood.
