Systemic resistance in maize

Most studies about induced resistance involve dicotyledonous plants such as Arabidopsis, tobacco or tomato. Despite the economical importance of maize, studies about its defenses are less common. The aim of this project is a better understanding of the mechanisms involved in systemic acquired resistance (SAR) and induced systemic resistance (ISR) in maize against different attacks (fungal pathogen and herbivores).

 

Colletotrichum graminicola, the causal agent of corn anthracnose, and Pseudomonas strains are used in this project as SAR and ISR inducers, respectively. As aboveground interactions have been more intensively studied than belowground interactions, we focus on shoot-to-root and vice versa signaling.
