Rcc inoculation of a barley leaf. A) 12dpi symptoms of the RLS

During his PhD studies, Jean-Baptiste Lopez researched the role of effector proteins in the interaction between barley and the fungus Ramularia collo-cygni. Ramularia collo-cygni is the agent of an emerging barley disease: the RLS (Ramularia leaf spot disease). Effector proteins are important tools secreted by microorganisms in order to fight the host immune defenses. During his PhD studies, Jean-Baptiste Lopez screened for new effectors used by Ramularia in order to infect barley, and studied more specifically the role of chitin binding effectors in this interaction.

The new research findings contribute to the understanding of how the RLS develop on barley at the molecular level and hence contribute to the understanding of how RLS control and prevention could be achieved.

The PhD degree was completed at the Department of Molecular Biology and Genetics, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
