What 2,900 wild grapevines reveal about the genetic diversity of Vitis vinifera L. subsp. sylvestris
Vitis vinifera L. subsp. sylvestris is the wild ancestor of the European cultivated grapevine (V. vinifera L. subsp. sativa).
A NAC-centered transcriptional network as a core regulatory module controlling the onset of grape berry ripening
The onset of fruit ripening represents a major developmental transition characterized by extensive transcriptional and metabolic reprogramming that determines fruit texture, color, flavor, and aroma.
Dissection of the Rpv12 locus: from the genetic basis to the phenotype
Modern viticulture relies predominantly on traditional European grapevine cultivars (Vitis vinifera) and is therefore heavily dependent on fungicide use to mitigate crop losses from downy (Plasmopara viticola)
Epigenetic regulation of APT3 seems to explain the masculinized phenotype of a floral mutant of Listán Prieto
While most cultivated grapevines (Vitis vinifera L.) possess perfect flowers, their wild ancestors were dioecious.
Functional dissection of grapevine resistance loci against Plasmopara viticola (Rpv) using a comparative multi-omics approach
Grapevine resistance breeding relies on a limited number of major resistance loci (Rpv) to control Plasmopara viticola.
Functional dissection of NPR3 by genome editing highlights its role in grapevine defense and root symbiosis
New Plant Breeding Techniques (NPBTs), and particularly genome editing, represent a powerful avenue to enhance disease resilience in perennial crops.
Haplotype diversity and marker development at grapevine (Vitis) disease resistance loci
Studying disease resistance loci in grapevines (Vitis) is a complex process because resistance QTL often coincide with highly-repetitive NLR gene clusters that are difficult to analysis bioinformatically, requiring extra time and attention to fully characterize.
Haplotype-resolved genome assembly and implementation of VitExpress, an open interactive transcriptomic platform for grapevine
In contrast to most crops, Vitis vinifera has benefited little from classical breeding due to its high heterozygosity.
Large-scale variant identification and annotation from whole-genome-sequencing data enables functional prediction in grapevine
Grapevine (Vitis vinifera) is amongst the world’s most cultivated fruit crops, and of global and economic significance.
Mapping of five loci for black rot resistance in four breeding populations and identification of candidate genes associated with Rgb1
Black rot, caused by Phyllosticta ampelicida (Guignardia bidwellii), is a serious fungal disease in viticulture. Incidences increased in recent years due to reduced pesticide treatments, neglected phytosanitary measurements, and effects of climate change.
miR7122-3p is a key regulating factor of the photosynthetic process in grapevine
Plant microRNAs are small regulatory RNAs that control gene expression and play key roles in plant development and stress adaptation.
QTL mapping and transcriptomics reveal complex and conserved regulation of graft union formation
Understanding how grafts form has fascinated scientists for over a century, and numerous transcription factors (TFs) involved in wound healing, callus formation, and graft development have been identified in model plants.
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.
