Organ-Specific Silencing of Duplicated Genes in a Newly Synthesized Cotton Allotetraploid [PDF]
Genetics, 2004 Abstract Most eukaryotes have undergone genome doubling at least once during their evolutionary history. Hybridization followed by genome doubling (allopolyploidization) is a prominent mode of speciation in plants, leading to phenotypic novelty and changes in genome structure and gene expression.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
