Focus Research
The long-term goals of my program are to understand how plant defense signaling pathways interconnect to function as a network in providing protection against a variety of pathogens. We use Arabidopsis and soybean as our experimental systems and study defense responses to viral (Turnip crinkle virus, Soybean mosaic virus), bacterial (Pseudomonas syringae), fungal (Botrytis cinerea) and oomycete (Phytophthora sojae) pathogens. Current projects relate to:
  • Identifying plant targets of bacterial and viral effectors
  • Understanding how glycerolipid metabolism interfaces with defense signaling
  • Determining the role of the plant cuticle in systemic immunity

  • PPA 500-001 Physiology of Plant Health & Disease
  • PPA 785-002 Special Problems in Plant Pathology
