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.
Proteomic insights into early grapevine defense responses to downy and powdery mildew
Grapevine is a globally significant crop whose productivity is constantly threatened by fungal and oomycete diseases.
CRISPR/Cas9-induced trehalase knockout for drought resistance in grapevine
Climate change is predicted to alter the water availability where grapevine is cultivated, potentially impacting grape yield and quality [1].
Bridging in vitro and in planta models: metabolic insights into grapevine stress responses
Rapid climate changes and increasing biotic pressures compromise grapevine production systems by threatening grape quality and production yields, thus increasing phytochemical dependence as a widely adopted mitigation strategy.
Physiological performance and targeted gene expression dynamics in ‘Italia’ table grapevine under prolonged water deficit
Water availability constraints are becoming a defining factor in Mediterranean viticulture, which requires a deeper understanding of cultivar-specific adaptive mechanisms to sustain yield and fruit quality.
Evidence of trans-annual epigenetic memories of stresses in grapevine
Epigenetics refers to the layer of genetic information carried in chromatin beyond the DNAsequence, including histone modifications, DNAmethylation and small RNAs.
Seasonal dynamics in grapevine physiological and transcriptomic responses to combined water and nitrogen limitation
The increasing occurrence of drought events poses a major challenge for viticulture, as water deficit negatively affects vine yield and berry quality.
Root system architecture plasticity in Vitis plants under progressive soil drying
Prolonged water deficits driven by climate change are increasingly affecting the viticultural sector highlighting the need for drought-tolerant rootstocks.
Dissecting the role of EPFL9-2 in grapevine root system architecture through rhizotron-based phenotyping
Epidermal Patterning Factors (EPFs) constitute a family of small, highly conserved peptides that regulate diverse physiological and developmental processes in plants.
Development of a wine with controlled origin from PIWI grape varieties
On the international wine market, wines that have a controlled (and guaranteed) origin from a specific wine-growing region enjoy special attention.
VvRefPanel field trial reveals new genetic determinants for abiotic stress tolerance in Vitis vinifera
Despite the urgent need for boosting grapevine breeding to face the threat of climate change, the genetic determinism of key traits related to phenology and leaf physiology have yet to be explored in a large diversity panel in the field.
Supporting grapevine breeding and research through sensor-based phenotyping applications
Phenotyping refers to the description of phenotypes and can range from morphological characteristics to plant compounts.
A morphological approach for the early selection of grapevine rootstocks tolerant to water stress
Over the past two decades, grapevine rootstock breeding programs have increasingly favored genotypes with a tendency toward anisohydric behavior, which are better adapted to hot and arid conditions.
