Effect of cryopreservation on genome mutation rate - examples of grapevine
Grapevine genetic resources are maintained in field collections being challenged by repeating biotic and abiotic stresses. Plant adapt to stress by increased mutation rates. Hence, long-term field collections may not be optimal to maintain original cultivars (and clones in grapevine). This project will quantify cryopreservation process-induced ...
Multispectral imaging: key to early leaf disease detection
Automated Airborne Pest Monitoring AAPM of Drosophila suzukii in Crops and Natural Habitats
Drosophila suzukii has become a serious pest in Europe since its spread in 2008 to Spain and Italy, attacking many soft-skinned crops such as several berry species, cherry and grapevines. Pest monitoring is the basis of its control. Therefore, an efficient and accurate monitoring system is essential in order to identify the presence of D. suzukii ...
Systemic disease response of Solanum lycopersicon
This project is part of COST Action FA1208 "Pathogen-informed strategies for sustainable broad-spectrum crop resistance". Late blight, caused by the oomycete Phytophthora infestans, is one of the major threats in potato (Solanum tuberosum) and tomato (Solanum lycopersicum) production. Facing the goals of COST Action FA1208 to gain knowledge on ...
Life cycle assessment of Swiss wine from conventional and organic farming
The consumption of food and beverages causes more than a quarter of an average person’s environmental impact in Switzerland. Apart from meat, fish and dairy products, beverage and semiluxury food – especially spirits and coffee – contribute to a significant share. Over the entire life cycle of wine – from the cultivation of the vineyard to ...
Occurence of grape phylloxera (Dactulosphaira vitifoliae) in Switzerland
Grape phylloxera (Daktulosphaira vitifoliae, Fitch) was a major pest in European grape production until the consequent use of resistant rootstocks. Today phylloxera is found mostly on derelict vineyards and interspecific hybrids used mainly in organic grapewine production. This project aims to map the occurence of grape phylloxera in Switzerland ...
Detection of Bois noir phytoplasma in the vectoring ciciid Hyalethes obsoletus.
Bois noir is a yellow disease of grapevines (Vitis vinifera) caused by phytoplasmas belonging to the class 'Candidatus Phytoplasma solani'. These phytoplasmas live mostly on bindweed (Convolvulus arvensis) and stinging nettle (Urtica dioica). By accident they are transmitted by the ciciid Hyalesthes obsoletus to V. vinifera. We investigate the ...
Expression of Vitis vinifera genes during downy mildew infection
Plasmopara viticola, an oomycete causing downy mildew of grapevines (Vitis vinifera), is one of the major pathogenes in grape production in many grape growing regions world wide. We are interested in genes of V. vinifera expressed during the first 24 h post inoculation.
