Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

Potato (Solanum tuberosum L.) is the world's most important non-cereal food crop, and the
vast majority of commercially grown cultivars are highly heterozygous tetraploids. Advances …

Deep knowledge of crop biodiversity is essential to improving global food security. Despite
bread wheat serving as a keystone crop worldwide, the population history of bread wheat …

Genome-scale sequence data have invigorated the study of hybridization and introgression,
particularly in animals. However, outside of a few notable cases, we lack systematic tests for …

Chloranthales remain the last major mesangiosperm lineage without a nuclear genome
assembly. We therefore assemble a high-quality chromosome-level genome of Chloranthus …

Polyploidy (genome duplication) is a pivotal force in evolution. However, the interactions
between parental genomes in a polyploid nucleus, frequently involving subgenome …

Introgression can be an important source of new alleles for adaption under rapidly changing
environments, perhaps even more important than standing variation. Though introgression …

Phylogenomics has revealed the remarkable frequency with which introgression occurs
across the tree of life. These discoveries have been enabled by the rapid growth of methods …

Chromosomes are a central unit of genome organization. One-tenth of all described species
on Earth are butterflies and moths, the Lepidoptera, which generally possess 31 …
