I discovered microorganisms during my childhood, studied them at university, started to work with them in a lab when I was an Erasmus exchange student. And now? I run the French Collection for plant-associated Bacteria. The collection provides microorganisms to scientists all over the world. We have resources which help us to better understand how some bacteria can attack plants and threaten agriculture. By doing so, we can better understand how to live with these microorganisms and learn how to reduce their negative impact. Some of these microorganisms belong to the IS_MIRRI21 European project which will make them accessible to all researchers in the world so that we can all know how to live better with them.
