Symbiotic and Plant Pathogen Interactions

Plants interact with a multitude of microorganisms in their environment. These microorganisms act alone or in community. They can have negative or positive effects on plants, their growth, their nutrition, their health. In this module, we will present the different forms that these biotic interactions can take (symbioses, parasitism-pathogenicity) based on popular biological models (mycorrhizal or nitrogen-fixing symbioses, diseases caused by different microorganisms). It will also be an opportunity to present emerging concepts in the field such as the microbiome or the holobiont.

Know the main types of biotic interactions

To know, in general, the mechanisms implemented by the plant during the initial stages and chronic phases of a biotic interaction.

Know how to inoculate a plant with a bacterium or a fungus and follow the appearance of symptoms (growth / disease / alteration of root development)
