Arabidopsis abiotic stress molecular biology nitrogen metabolism plant biochemistry plant biology plant development plant physiology soybean

In the Todd lab we are interested in the regulation of nitrogen metabolism and how it relates to plant growth and development. Most recently we have worked on the role of ureide metabolism and its relationship to abiotic stress.

Of particular interest in the lab right now is the role of effector proteins in mediating successful infections that lead to the establishment of clubroot disease in plants.
