Plant-Pathogen Interactions

Plant-pathogen interactions are complex relationships that significantly impact agriculture and ecosystems. These interactions can be classified into two categories: compatible and incompatible. In compatible interactions, pathogens successfully infect and exploit host plants, leading to disease, while in incompatible interactions, plants recognize and defend against pathogens through various defense mechanisms, including the hypersensitive response and systemic acquired resistance. Understanding these interactions at the molecular level is crucial for developing disease-resistant crops. Researchers study the molecular signals exchanged during these interactions, which can lead to the identification of novel resistance genes and strategies for enhancing plant immunity, ultimately contributing to sustainable agricultural practices.
