Genome duplication articles from across Nature Portfolio

Ginkgo biloba is well known for its unique morphological features, key phylogenetic position and long association with humans. A refined, high-quality reference genome of G. biloba helps to fix the problems in the draft release and understand the genetic basis of some important morphological features.

A high-quality sunflower genome provides insight into Asterid genome evolution. Moreover, integrative analyses based on quantitative genetics, expression and diversity data uncover the gene networks and candidate genes for oil metabolism and flowering time, two important agronomic traits for sunflowers.

Galluzzi and Kroemer take advantage of a large study of somatic copy number alterations to revisit the previously suggested idea that cancer aneuploidy frequently arises from genome duplication.
