Plant Materials

We are investigating the effects of polyploidy in three plant systems: Arabidopsis, Brassica and corn. These systems were chosen because each has advantages for addressing questions about polyploidy.

Arabidopsis has closely related diploid and polyploid species, and analogs of the natural polyploids can be resynthesized from the diploid species. The wealth of genetic stocks, biological information, and genomics resources available for this model organism will allow us to broadly and deeply explore the effects of polyploidy on plant function.

Brassica includes diploid and polyploid species that are grown as crop plants throughout the world. Polyploids can be resynthesized from diploid species in such a way as to create very pure (homozygous) genetic stocks for analysis. Brassicas are closely related to Arabidopsis, making many of the Arabidopsis genomics tools useful for analyzing Brassica.

Corn (Zea maize) is a diploid species and a major grain crop grown throughout the world. Autopolyploid series can be created for corn and hybrids can be made between polyploid genotypes, allowing us to study the relationship of polyploidy and heterosis. There are many genomic resources available for the study of corn.
