Plant Defense Mechanisms: Herbivore-Induced Resource Sequestration
Project Leader: Colin Orians
Plants have evolved diverse mechanism to avoid herbivory.
While many researchers focus on induced resistance our research
focuses on aspects of induced tolerance, specifically induced
resource sequestration. This research promises to expand our
understanding of how plants defend themselves against herbivores.
We have demonstrated that herbivore cues cause greater export of resources from local and systemic leaf tissue and this results in an increase in resource pools in stem tissue. More recent work has examined the conditions that are expected to favor resource allocation as compared to growth and defense. Overall this work highlights the importance of taking a whole plant perspective when examining how plants defend themselves against herbivores.
