Physiology, Biochemistry, and Toxicology / Plant-Insect Interactions

Fiona Goggin

Dr. Fiona Goggin's research is focused on plant defenses against herbivory, with an emphasis on mechanisms of resistance against vascular feeders such as aphids and root-knot nematodes. The Insects-Plant Interaction Laboratory is comprised of separate laboratories. The laboratories are well-equipped to conduct research in insect-plant interactions and physiology. We have equipment for preparation and analysis of plant natural products. We are also equipped for work with proteins and nucleic acids. And, we have ample growth chamber space for bioassays. Additionally, we maintain a greenhouse.

Current Research and Extension Projects:

  • Broad-spectrum, induced defenses against herbivores and isolate-specific, resistance-gene-mediated innate resistance, and utilizes molecular and genomic approaches to identify potential sources of resistance against insects. 
  • Vascular feeders can cause massive physiological changes in their host plant such as galling, and many of these herbivores are also important vectors of plant pathogens. Their interactions with plants are therefore important from both an ecological and a practical agricultural perspective. Despite this relatively little is known about the physiological or molecular basis of plant responses to vascular herbivory. 
    •  Tomato (Solanum lycopersicum) and Arabidopsis thaliana are used as as model systems to investigate the physiological or molecular basis of plant responses to vascular herbivory.
    •  Tomato (Solanum lycopersicum) and Arabidopsis thaliana  also are used as as model systems to explore the relationship of plant defensive pathways induced by aphids and nematodes to plant defenses against other biotic and abiotic stresses.
