Targeted long-read sequencing reveals function-restoring MYBA1 and MYBA2 mutations in white-to-red grape color somatic variants
To diversify production, vinegrowers select somatic variants in grape color that arise spontaneously during the propagation of cultivars.
Prediction-based approaches for grapevine improvement
Grapevine breeding is fundamentally constrained by long generation times, perennial growth and clonal propagation.
A Portuguese grapevine breeding program focused on enhancing resistance to Plasmopara viticola and Erysiphe necator
Downy mildew (Plasmopara viticola) and powdery mildew (Erysiphe necator) are among the most destructive diseases affecting grapevine (Vitis vinifera L.).
Evaluation of 21 new disease-resistant winegrape varieties (PIWI) for viticultural suitability in north-eastern Italy
The cultivation of disease-resistant winegrape varieties (PIWI) is gaining interest worldwide, particularly in viticultural areas where the use of fungicide is limited.
Genomic and epigenomic contributions to trait variation, genotype-by-environment interactions, and stability in grapevine clones
Clonal selection remains central to grapevine improvement, yet consistent yield and fruit quality across vintages are challenged by pronounced genotype-by-environment interactions (G×E).
Grapevine breeding for the development of multi-disease-resistant cultivars through marker-assisted selection and resistance gene pyramiding
The climatic conditions of southern Brazil favor the incidence of fungal diseases in grapevines, which hampers the cultivation of Vitis vinifera varieties.
Genetic insights into Georgian grapevine germplasm
The South Caucasus is widely recognized as a primary center of grapevine domestication (Vitis vinifera L.).
Induced mutagenesis as a tool for intra-varietal improvement: increased diversity in vegetative, fruit and phenological traits in Vitis vinifera cv. Pinotage
Climate variability and rising biotic pressure threaten global viticulture. Modern wine production depends on a limited number of grapevine cultivars, represented by multiple clones that differ slightly in their agronomic, oenological, or stress-tolerance traits.
Reviving grapevine massal selection in the context of climate change: A strategy for resilient vineyards in the 21st century
Modern viticulture faces a critical paradox. The widespread adoption of clonal selection in the mid-20th century successfully standardized production and reduced viral incidence through sanitization and certification, but unintentionally created a genetically simplified vineyard landscape.
Strategic advancement of the Korean table grape breeding program for consumer-preferred cultivars
In Korea, summer rainfall and comparatively less favorable growing conditions than major grape-producing countries have influenced the direction of table grape breeding.
VitisGen3: completing the grapevine powdery mildew pipeline
Past VitisGen projects (VitisGen, 2012-2017, and VitisGen2, 2017-2022) generated groundbreaking technologies for the grapevine breeding community, from low-cost DNAmarker platforms to advances in computer vision phenotyping.
Genetic insights into recently discovered indigenous grapes from historical Armenian vineyards: implications for conservation and breeding
Grapevine (Vitis vinifera L.) is one of the most ancient and culturally significant plant species, domesticated over 11,000 years ago.
Sativa introgression in Croatian wild grapevine
The wild grapevine, Vitis vinifera L. subsp. sylvestris (Gmelin, Hegi), is spontaneous to Europe and has gained increasing scientific attention in recent years due to its rapidly declining populations and its valuable, yet largely unexplored, genetic pool.
Progress toward less susceptible grapevines to vector-borne diseases
Grapevine diseases pose a major threat to viticulture worldwide, causing substantial yield losses and jeopardizing the long-term sustainability of vineyard systems.
A population-scale analysis of genetic, epigenetic, and phenotypic variation in Pinot clonal populations
Clonal selection has been used for centuries to improve major grapevine varieties, yet the molecular mechanisms responsible for phenotypic variation among clones remain poorly understood.
Diploid genome assembly and annotation provide insights into allele-specific variants underlying fruit-quality QTLs
Fruit-quality traits including berry aroma and bunch architecture are major targets for improvement in both the wine and table grape industry.
Are specific microbiota from the phyllosphere of American Vitis species involved to their resistance to downy mildew?
The oomycete Plasmopara viticola (Berk. & M.A. Curtis) Berl. & De Toni, the causal agent of grapevine downy mildew, originated in the northeastern United States and was accidentally introduced into Europe in the mid-19th century.
Deciphering the hormonal regulatory networks underlying grape berry resistance to Botrytis cinerea
Botrytis cinerea is a major fungal pathogen affecting viticulture, causing substantial economic losses due to reduced fruit quality and subsequent yield.
Identification and functional validation of a grapevine downy mildew resistant NLR gene through biparental graph-based forward genetics
Grape downy mildew, caused by the oomycete Plasmopara viticola, is one of the major diseases threatening the viticulture industry.
Decoding lipid signaling in grapevine – Plasmopara viticola interaction: from host membrane remodeling to oomycete-derived lipid elicitors
Over the past decades, lipids and fatty acids have emerged as pivotal regulators of plant–pathogen interactions.
