AbstractDie Studierenden der Agrar- und Lebensmittelwissenschaften erarbeiten in interdisziplinären Teams Lösungen für Probleme, welche ihnen von Projektpartner im Bereich der Nahrungsmittelwertschöpfungskette gestellt werden.
ObjectiveDie Studierenden kennen
- die Grundlagen des Zeit- und Projektmanagements
- Vorgehensweisen, um Probleme, die ihnen von Projektpartnern gestellt werden, zielorientiert zu lösen.
ContentDie Studierenden der Agrar- und Lebensmittelwissenschaft erarbeiten in interdisziplinären Teams Lösungen für Probleme, welche ihnen von Projektpartnern entlang der Nahrungsmittelwertschöpfungskette gestellt werden. Die Studierenden präsentieren und diskutieren die Lösungsvorschläge an der Schlussveranstaltung mit den Projektpartnern und verfassen einen schriftlichen Projektbericht.
Prerequisites / NoticeDie Anwesenheit der Studierenden an der Startveranstaltung am 26.2.2015 gemäss speziellem Programm ist Pflicht.
751-4505-00LPlant Pathology II2 credits2GB. McDonald, U. Merz
AbstractPlant Pathology II focuses on disease control in agroecosystems based on biological control, pesticide applications and breeding of resistant crop cultivars. The genetics of pathogen-plant interactions will be explored in detail as a basis for understanding the development of boom-and-bust cycles and methods that may be used to prevent the evolution of pathogen virulence and fungicide resistance.
ObjectiveAn understanding of the how biological control, pesticides and plant breeding can be used to achieve sustainable disease control. An understanding of the genetic basis of pathogen-plant interactions and appropriate methods for using resistance to control diseases in agroecosystems.

Lecture Topics and Tentative Schedule

Week 1 Biological control: biofumigation, disease declines, suppressive soils.

Week 2 Biological control: competitive exclusion, hyperparasitism.

Week 3 Chemical control: History of fungicides in Europe, fungicide properties, application methods.

Week 4 Fungicide categories and modes of action, antibiotics, fungicide development, fungicide safety and risk assessment (human health).

Week 5 Resistance to fungicides. Genetics of fungicide resistance, ABC transporters, risk assessment, fitness costs. FRAC risk assessment model vs. population genetic risk assessment model.

Week 6 Genetics of pathogen-plant interaction: genetics of pathogens, genetics of plant resistance, major gene and quantitative resistance, acquired resistance. Flor's GFG hypothesis and the quadratic check, the receptor and elicitor model of GFG, the guard model of GFG.

Week 7 Resistance gene structure and genome distribution, conservation of LRR motifs across eukaryotes. Genetic basis of quantitative resistance. QTLs and QRLs. Connections between MGR and QR. Durability of QR.

Week 8 Genetic resistance: Costs, benefits and risks.

Week 9 Non-host resistance. Types of NHR. NHR in Arabidopsis with powdery mildews. NHR in maize and rice. Avirulence genes and pathogen elicitors. PAMPs, effectors, type-III secretion systems, harpins in bacteria. Fungal avirulence genes.

Week 10 Easter holiday no class.

Week 11 Sechselauten holiday no class.

Week 12 Host-specific toxins. GFG for toxins and connection to apoptosis. Fitness costs of virulence alleles. Diversifying selection in NIP1.

751-4506-00LPlant Pathology IV Information 2 credits2GU. Merz, M. Maurhofer Bringolf
AbstractIdentification based on host, symptoms and micro-morphology, completed with life cycles and related control measures of the most important fungal diseases and their causal pathogens of annual and perennial crops with agricultural significance.
ObjectiveThe students will learn and train preparation skills for microscopy, aquire knowledge of selected diseases (identification, biology of pathogen, epidemiology) and understand the corresponding integrated control measures practiced in Swiss agriculture.
ContentThe course will partly be an e-learning excercise (with computers).
Lecture notesA script will be used on annual and perennial crops and their most important diseases. It will be updated stepwise
Prerequisites / NoticeThe course will be in German (spec. nomenclature)
