Research Summary

Engineering monoterpene synthesis in Camelina sativa; a non-food biofuels crop

Omics approaches to characterizing Taxol synthesis

Auxin biosynthesis in plants and microbes

We use a variety of plant systems including the model flowering plant, Arabidopsis thaliana, the non-food crop Camelina sativa and Nicotiana benthamiana to either engineer plant metabolism or study the biosynthesis of plant specialized metabolites. Mass spectrometry features prominently in our experimental approaches. For example, we use stable isotope labeling and metabolite profiling to examine the regulation of plant growth and development by the signaling molecule indole-3-acetic acid (IAA), also known as auxin and to examine flux through the 2-C-methyl-D-erythritol 4-phosphate (MEP; aka the non-mevalonate pathway) in Camelina sativa lines engineered to produce monoterpenes for biofuels applications. We are working with campus colleagues to mine a recently acquired plant cell culture collection for new molecules with industrial, pharmaceutical and agricultural applications.
