Grapevine Fanleaf Virus: Biology, Biotechnology And Resistance
Grapevine fanleaf virus (GFLV) causes fanleaf degeneration of grapevines. GFLV is present in most grape growing regions and has a bipartite RNA genome. The three goals of this research were to (1) advance our understanding of GFLV biology through studies on its satellite RNA, (2) engineer GFLV into …

PHENOTYPING OF GRAPEVINE ROOT SYSTEM FOR DROUGHT ADAPTATION
… the outbreak of Phylloxera in the 19th century grapevine has been predominantly propagated through grafting and rootstocks have become essential tools to regulate plant vigour, nutrient uptake and tolerance to abiotic stresses, including drought. However, currently available rootstocks derive …

INFLUENCE OF THE INTERACTION SCION X ROOTSTOCK ON GRAPEVINE RESPONSE TO DROUGHT STRESS AS A TOOL IN NEW GRAPEVINE ROOTSTOCKS BREEDING PROGRAMS.
… were selected in the late 19th century, when grapevine cultivation practices vastly differed from those of today. As a result, there is a growing demand for drought-tolerant rootstocks that are suitable for modern viticulture. In response to this request, some new genotypes have been released …

Genetic analysis of agronomic and enological traits in grapevine
In order to select improved genotypes with potential for producing high-quality wines in a climate change scenario, asegregating F1 population with 151 progeny derived from a cross between Graciano x Tempranillo was studied for14 agronomic traits, 11 enological traits and 5 seed traits for three …

PHYTOPLASMAS-ENDOPHYTES INTERACTIONS: THE CASE STUDY OF GRAPEVINE YELLOWS RECOVERY
… bacteria and phytoplasmas associated with grapevines to clarify the role of endophytic bacteria in grapevine yellows (GY) recovery and discuss the possibility to apply these bacteria for GY management. Diversity of bacterial endophytes associated with grapevine leaf tissues was analyzed by …

Genome editing for engineering resilience to climate changes in grapevine
… of the Epidermal Patterning Factor family. In grapevine, two EPFL9 paralogs exist, VviEPFL9-1 and VviEPFL9-2 but despite a structural similarity, their specific function remains unclear. In this study, we investigated their distinct functional roles and the extent to which reduced stomatal …

Phaeomoniella chlamydospora: potential inoculum sources in the grapevine propagation process
… recently described fungal pathogen that infects grapevines causing Petri disease, which is observed externally as a general decline. The objective of this research programme was to identify potential sources of inoculum in the grapevine propagation process (including propagation material, the …

Chemical characterisation of grapevine waste and bioactivity on cancer cell lines
Grapevine waste is a potential source of bioactive phenolic compounds. Solvent extracts of stems, skins and defatted seeds from grapevine waste of both noble French and indigenous Maltese grapevine cultivars were studied. The individual parts were air dried and subjected to polar solvent extraction …

Documentation of grapevine leafroll-associated viruses in wine grape varieties and native grape species in Virginia, and examination of the movement of grapevine leafroll disease to develop management strategies
Grapevine leafroll-associated virus-2 (GLRaV-2), GLRaV-3, and grapevine fleck virus (GFkV) are widespread in grapes around the world. These viruses can cause significant crop loss and affect wine quality by reducing sugar accumulation and compromising skin color. Mealybugs are vectors of grapevine …

Integrating Genomics and Metabolomics to Inform Breeding for Powdery Mildew Resistance in Grapevine
Two powdery mildew resistance loci have been identified using pedigree-connected F1 mapping families at the University of Minnesota grape breeding program. A consensus linkage map of the resistant parent (MN1264) was developed for genetic mapping. The resistance loci were mapped on chromosomes 2 …
