Background Despite the prevalence and recurrence of polyploidization in the speciation of
flowering plants, its impacts on crop intraspecific genome diversification are largely …

Background Brassica rapa is one of the most economically important vegetable crops
worldwide. Owing to its agronomic importance and phylogenetic position, B. rapa provides a …

Polyploidization, both ancient and recent, is frequent among plants. A “two-step theory" was
proposed to explain the meso-triplication of the Brassica “A" genome: Brassica rapa. By …

Background Brassica oleracea is a valuable vegetable species that has contributed to
human health and nutrition for hundreds of years and comprises multiple distinct cultivar …

Polyploidization has provided much genetic variation for plant adaptive evolution, but the
mechanisms by which the molecular evolution of polyploid genomes establishes genetic …

Polyploidization has played a major role in crop plant evolution, leading to advantageous
traits that have been selected by humans. Here, we describe restructuring patterns in the …

Background Brassica rapa is an economically important crop species. During its long
breeding history, a large number of morphotypes have been generated, including leafy …

Brassica species, including crops such as cabbage, turnip and oilseed, display enormous
phenotypic variation. Brassica genomes have all undergone a whole-genome triplication …

The cultivated Brassica species include numerous vegetable and oil crops of global
importance. Three genomes (designated A, B and C) share mesohexapolyploid ancestry …

The genus Brassica belongs to the plant family Brassicaceae, which includes many
important crop species that are used as oilseed, condiments, or vegetables throughout the …
