Genome duplication articles from across Nature Portfolio

An efficient method of cyto-swapping by haploid induction using a CENH3 mutation is reported in maize, to convert commercial germplasm to cytoplasmic male sterility for hybrid seed production.

Epigenetic control of extrachromosomal circular DNA (eccDNA) compartment and the relationships between eccDNA and plant genome stability remain unclear. Here, the authors investigate eccDNA and structural variations in Arabidopsis epigenetic mutants to reveal the eccDNA repertoire and its impact on genome stability.

A chromosome-scale genome assembly for rhubarb combined with transcriptomic data provides insight into the molecular mechanisms regulating anthraquinone biosynthesis in this plant.

Genome sequencing and analyses of common buckwheat, Fagopyrum esculentum, reveal the genetic architecture of heterostyly, show that southeast Tibet played a key role in the domestication and provide new genetic materials for buckwheat breeding.

Horseradish is a spicy root vegetable and it also produces horseradish peroxidase, an enzyme widely used in biochemistry applications. Here, the authors report its telomere-to-telomere reference genome, reveal subgenome diversification and the effect on the biosynthesis of glucosinolates and horseradish peroxidases.

Asteraceae is the largest family of flowering plants. Here, the authors assemble the genomes of stem lettuce (within Asteraceae) and beach cabbage (within Goodeniaceae) for evolutionary genomics analyses and reveal the absence of the core regulatory gene of nitrogen and carbon assimilation in Asteraceae.

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.
