The main objective of BIORES is to explore natural and biotechnological resources for genetic resistance of grapevine against Flavescence dorée (FD). This important quarantine disease, caused by phytoplasmas strains within the 16SrV ribosomal group, is controlled only by indirect and preventive measures, with important economic and environmental concerns. Genetic resources from the great variety of Vitis vinifera germplasm together with application of new frontiers of bioengineering and genome editing through CRISPR-Cas, will be applied to produce resistant/tolerant plants with obvious improvement of vineyard sustainability. The project will firstly evaluate different grapevine cultivars’ responses to FD infection under controlled conditions, including testing susceptibility of dwarf mutant microvines. Secondly, it will analyze potential resistance- and susceptibility-related genes using existing knowledge and literature data to identify promising targets for biotechnological manipulation. BIORES aims to enhance understanding and practical solutions for managing FD in grapevines, benefiting both vineyard practices and scientific advancements in plant pathology.
