Project description
Disease management remains one of the key components in viticultural production systems. It also remains one of the major expenses in production and together with unpredictable climatic factors, one of the most important risk factors that could negatively impact grapevine products. Modern agriculture has dealt with this reality by improving natural resistance against pathogens by resistance breeding, as well as comprehensive use of agrochemicals. Both these strategies have limits, and the use of agrochemicals in addition has extremely negative effects on the environment, as well as poses potential risks to consumers regarding harmful residues and product safety. Most grapevine producers around the world aim to optimise production and product quality; minimise the negative impact on the environment, while maintaining or improving cost effectiveness and product safety. These broad industry aims provide the outcomes that we work towards in the Grapevine Biotechnology Programme of the IWBT. Within the project theme of Understanding and manipulating disease resistance in grapevine the specific objectives are to improve our understanding of the biology of grapevine regarding disease resistance and to use this knowledge in providing alternative strategies (and/or) plant material for disease management.
The proposed projects follow on previously funded projects supported by Winetech, DFPT, NRF, and THRIP and benefit from the progress made in these projects, as well as the development and accumulation of methods and expertise. The proposed research will almost exclusively use grapevine as the study model since significant genetic resources and methodologies have been developed in Vitis vinifera to support both the fundamental and applied aspects of the projects. Moreover, in addition to our existing focus on Botrytis cinerea as a fungal model pathogen, several major grapevine fungal pathogens will also be included in the experiments.
