The biology of plant biotic interactions

The biology of plant biotic interactions: plant diseases and pests, integrated crop protection, symbionts, population ecology


Closely linked to plant biology, the goal of this research area is to understand the role played by interactions with other living organisms in the development and functioning of plants, whether these interactions are symbiotic or bio-aggressive and defensive. It mobilises genomics, genetics, chemistry, epidemiology, ecology, population ecology, modelling, crop protection engineering, and biocontrol.
It studies the interactions between plants and microorganisms (viruses, bacteria, fungi) and macroorganisms (nematodes, insects, etc.). It focuses on understanding the role of the phytobiome, its characteristics and dynamics, and the processes involved for example in symbiotic nutrition in plants. It looks at bio-aggression mechanisms and strategies as well as plant defence mechanisms and strategies, and the development of resistance in plants and their pests. It studies the dynamics involved in the spread of diseases and pests. Finally, it aims to develop crop protection and defence strategies that minimise the use of chemical inputs. It covers a wide range of temperate, Mediterranean and tropical phytopathosystems.
