Insect-microbe associations that influence the impact of plant defenses are likely widespread. We are studying how these associations function to overcome plant defenses in both wheat as well as other aphid-bacteria-plant systems.
Warming in the climate system impacts plant biology in many ways, including how plants respond to pathogens. Many plant diseases are predicted to intensify as environmental temperatures increase, and many widely used single gene sources of disease resistance (R genes) are less effective at high temperatures. We are studying how high temperature impacts disease and resistance using rice and the bacterial blight pathogen as a system.
