Metabolic Engineering and Plant Natural Products Research
Metabolic engineering for plants is the manipulation of biochemical, genetic and regulatory processes within plant cells to increase the production of specific plant chemicals, particularly plant natural products. Noble Foundation scientists and researchers seek to understand the fundamental structures and chemistry of these compounds for agriculturally significant plants, such as grasses and legumes, as well as the mechanisms and pathways necessary to form, deliver and store such compounds. Research at the Noble Foundation targets the production of plant natural products to benefit human and animal health as well as the production of compounds to assist plants in defending themselves against fungal pathogens.

- Development of comparative functional genomics for plant trichomes (Dixon, Sumner, Zhao)
- Study of the biosynthesis of C-glycosyl isoflavones in kudzu (Dixon)
- Identification and evaluation of grape seed polyphenols and their relationship to Alzheimer's disease (Dixon)
- Discovery and elucidation of genes involved in triterpene saponin biosynthesis (Sumner, Dixon)
- Genetic modification of alfalfa to introduce tolerance to Phymatotrichum root rot (or cotton root rot) (Dixon, Sumner, Mysore)
- Study of the glycosylation of plant natural products and the enzymatic mechanism of uridine diphosphate glycosyltransferases (Wang)
