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.
Origin of hemizygosity in grape: the case study of cv. Merlot
Hemizygous genes, are genes present on only one copy of the genome (only one allele) and should not be confused with homozygous genes.
Multi-dimensional characterization of grape berry cuticles and their usability for an improved breeding of Botrytis bunch rot resilience
For one of the major fungal diseases in cool-climate viticulture, Botrytis bunch rot (BBR), management practices as well as plant protection possibilities reach their limits.
Breeding for climate adaption should avoid a widely distibuted allele within the Ver1 veraison locus
In the past breeding programmes for grapevine varieties for cool climate focused on developing early ripening cultivars that are better adapted to the prevailing climatic conditions.
Uncovering novel epigenetic traits in grapevine resistance against downy and powdery mildew – A multi-omics approach
As one of the most important crop plants in the world, securing grapevine yields and production quality is a top priority.
Building an integrated, high-throughput pipeline to accelerate grapevine improvement in New Zealand
The value that perennial crop improvement can offer is constrained by the lag between when growers define a problem and when genetic solutions reach the vineyard.
Polyclonal selection in ancient grapevine varieties: genetic gains and stability across environments
Conserving and exploiting intra-varietal diversity in ancient grapevine varieties is essential to secure their future use whilst preserving the genetic heritage of historical winegrowing regions.
Chloroplast-related pathways involved in grapevine drought responses
Water scarcity is an increasing constraint for viticulture in Mediterranean regions, making the identification of molecular mechanisms underlying drought tolerance a key objective for grapevine breeding and management.
Grapevine DMR6-1 DMR6-2 double mutants display constitutive systemic acquired resistance and altered gibberellin metabolism
Achieving disease resistance in grapevine (Vitis vinifera) without compromising plant growth is a significant challenge for viticulture. Astrategy to reduce susceptibility to Downy Mildew (DM) is through dual inactivation of the salicylic acid (SA) hydroxylases VviDMR6-1 and VviDMR6-2 by gene editing, which leads to elevated endogenous SAlevels and enhanced immunity.
