Perilla is a young allotetraploid Lamiaceae species widely used in East Asia as herb and oil
plant. Here, we report the high-quality, chromosome-scale genomes of the tetraploid (Perilla …

Oilseed rape (Brassica napus L.) was formed~ 7500 years ago by hybridization between B.
rapa and B. oleracea, followed by chromosome doubling, a process known as …

The biogeographic history of polyploids and their lower-ploid ancestors is an important
feature to achieve a better understanding of polyploid evolution. This is exemplified here …

Background Panax L. is a medicinally important genus within family Araliaceae, where
almost all species are of cultural significance for traditional Chinese medicine. Previous …

Recent studies have elucidated the ancient polyploid history of the Arabidopsis thaliana
(Brassicaceae) genome. The studies concur that there was at least one polyploidy event …

Monocots are a major taxon within flowering plants, have unique morphological traits, and
show an extraordinary diversity in lifestyle. To improve our understanding of monocot origin …

Interspecific hybridization and polyploidization have played central roles in plant
diversification. However, technical difficulties in the analyses of low-copy genes have limited …

Abstract Peonies (the Paeoniaceae, Paeonia L.) are famous garden flowers, medicinal
plants, and edible oil crops, but their evolutionary history largely remains unknown. To probe …

This article describes the use of cytogenomic and molecular approaches to explore the
origin and evolution of Cardamine schulzii, a textbook example of a recent allopolyploid, in …

Hybridization and polyploidization are important driving forces in angiosperm evolution,
resulting in novel phenotypes capable of prompting ecological diversification and invasion …
