Abstract excerpt
Whole-genome duplication, which leads to polyploidy, has been implicated in speciation and biological novelty. In plants, many species exhibit ploidy variation, which is likely representative of an early stage in the evolution of polyploid lineages. To understand the evolution of such multiploidy systems, we must address questions such as whether polyploid lineage(s) had a single or multiple origins, whether...
