Microbe-microbe interactions
Module 5

Prof. Costas Ehaliotis, Agricultural University of Athens, Greece

Lecturers:
• Prof. A. Chatzinotas, Helmholtz Centre for Environmental Research, Germany
• Prof. K. Koutsoumanis, Aristotle University of Thessaloniki
• Prof. Costas Ehaliotis, Agricultural University of Athens, Greece
• Dr P. Kougias, Hellenic Agriculture Organization-DEMETER, Greece
• Dr S. Ntougias, Democritus University of Thrace, Greece
• Dr. A. Gobet, France
• Prof. K. Kormas, University of Thessaly, Greece
• V Kokkoris, VU University Amsterdam

Learning outcomes

The students are expected at the end of the module to:

• Identify and become familiar with model microbe-microbe interactions currently known
• Get a good knowledge of the key microbial players in microbe-microbe interactions
• Get a good understanding of the mechanisms driving microbe-microbe interactions including responses to abiotic factors
• Understand the evolutionary drivers of established microbe-microbe interactions and co-evolution processes between the interacting microbes
• Combine pairwise to -biome approaches

The above learning objectives will be discussed at different integration levels: from genes and molecules to whole organisms and populations in an environment-dependent context
