Impacts of reproductive systems on grapevine genome and breeding [PDF]

Nature Communications
Diversified reproductive systems can be observed in the plant kingdom and applied in crop breeding; however, their impacts on crop genomic variation and breeding remain unclear. Grapevine (Vitis vinifera L.), a widely planted fruit tree, underwent a shift from dioecism to monoecism during domestication and involves crossing, self-pollination, and ...

New Technologies and Strategies for Grapevine Breeding Through Genetic Transformation. [PDF]

Front Plant Sci, 2021
Grapevine, as other woody perennials, has been considered a recalcitrant crop to produce transgenic plants. Since the production of transgenic and/or edited plants requires the ability to regenerate plants from transformed tissues, this step is often the biggest bottleneck in the process.

200 years Mendel: the grapevine breeding perspective

Journal für Kulturpflanzen, 2022
Mendelian rules in grapevine breeding remained hidden for a long time in the complexity of traits and difficulties of hand­ling the crop. A few traits with minor relevance for breeders had been genetically dissected like berry color or autumn leaf color. Mildew resistance and wine quality have been and are still the most relevant traits.

Relieving the Phenotyping Bottleneck for Grape Bunch Architecture in Grapevine Breeding Research: Implementation of a 3D-Based Phenotyping Approach for Quantitative Trait Locus Mapping

Horticulturae, 2022
In viticulture, winemakers and the industry demand grape bunches that have a reduced degree of bunch compactness. The major aspect is that a loose bunch compactness reduces the risk of severe Botrytis bunch-rot infections. Grapevine breeders focus hereby

Hyperspectral differentiation of three grapevine yellows diseases and symptomatically similar stresses. [PDF]

Front Plant Sci
PurposeThe study aims to develop a method for detecting and discriminating grapevine yellows (GY) diseases, including Flavescence dorée (FD), Bois noir (BN), and Palatinate grapevine yellows (PGY), using hyperspectral imaging (HSI).

High-Throughput Phenotyping of Leaf Discs Infected with Grapevine Downy Mildew Using Shallow Convolutional Neural Networks

Agronomy, 2021
Objective and standardized recording of disease severity in mapping crosses and breeding lines is a crucial step in characterizing resistance traits utilized in breeding programs and to conduct QTL or GWAS studies.

Confirmation and Fine Mapping of the Resistance Locus Ren9 from the Grapevine Cultivar ‘Regent’

Plants, 2020
Grapevine (Vitis vinifera ssp. vinifera) is a major fruit crop with high economic importance. Due to its susceptibility towards fungal and oomycete pathogens such as Erysiphe necator and Plasmopara viticola, the causal agents of powdery and downy mildew (

Transcriptomic analysis of temporal shifts in berry development between two grapevine cultivars of the Pinot family reveals potential genes controlling ripening time

BMC Plant Biology, 2021
Background Grapevine cultivars of the Pinot family represent clonally propagated mutants with major phenotypic and physiological differences, such as different colour or shifted ripening time, as well as changes in important viticultural traits ...

Towards Sensor-Based Phenotyping of Physical Barriers of Grapes to Improve Resilience to Botrytis Bunch Rot

Frontiers in Plant Science, 2022
Botrytis bunch rot is one of the economically most important fungal diseases in viticulture (aside from powdery mildew and downy mildew). So far, no active defense mechanisms and resistance loci against the necrotrophic pathogen are known.
