Polyploidy has long been recognized as a prominent force shaping the evolution of eukaryotes,
especially flowering plants. New phenotypes often arise with polyploid formation and …

It is difficult to overstate the cultural and biological impacts that the domestication of plants
and animals has had on our species. Fundamental questions regarding where, when, and …

Whole genome duplications (WGDs) followed by diploidization, which includes gene loss,
have been an important recurrent process in the evolution of higher eukaryotes. Gene …

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 allopolyploidy…

We report the annotation and analysis of the draft genome sequence of Brassica rapa accession
Chiifu-401-42, a Chinese cabbage. We modeled 41,174 protein coding genes in the B. …

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

Many previous studies have provided evidence for genome changes in polyploids, but there
are little data on the overall population dynamics of genome change and whether it causes …

Coevolutionary interactions are thought to have spurred the evolution of key innovations
and driven the diversification of much of life on Earth. However, the genetic and evolutionary …

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 groups …

Polyploidy has contributed to the evolution of eukaryotes, particularly flowering plants. The
genomic consequences of polyploidy have been extensively studied, but the mechanisms for …
