High-Precision Phenotyping of Grape Bunch Architecture Using Fast 3D Sensor and Automation

Sensors, 2018
Wine growers prefer cultivars with looser bunch architecture because of the decreased risk for bunch rot. As a consequence, grapevine breeders have to select seedlings and new cultivars with regard to appropriate bunch traits.

Phased grapevine genome sequence of an Rpv12 carrier for biotechnological exploration of resistance to Plasmopara viticola

Frontiers in Plant Science, 2023
The downy mildew disease caused by the oomycete Plasmopara viticola is a serious threat for grapevine and can cause enormous yield losses in viticulture. The quantitative trait locus Rpv12, mediating resistance against P.

Identification of sex determination locus and development of marker combination in Vitis based on genotyping by target sequencing

Fruit Research, 2023
The grapevine is an important and economically valuable fruit crop, with flower sex being a key genetic trait that directly affects grapevine yield and quality. Despite its significance, there is a lack of studies on sex-linked molecular markers that can

Identification of Vitis riparia as Donor of Black Rot Resistance in the Mapping Population V3125 x ‘Börner’ and Additive Effect of Rgb1 and Rgb2

Agronomy
Viticulture is facing challenges, like the impact of climate change and various pests and pathogens. Alongside powdery and downy mildew, black rot is one of the most prevalent fungal diseases in European wine-growing regions.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Rpv10.2: A Haplotype Variant of Locus Rpv10 Enables New Combinations for Pyramiding Downy Mildew Resistance Traits in Grapevine

Plants
In viticulture, pathogens like the oomycete Plasmopara viticola, the causal agent of downy mildew, can cause severe yield loss and require extensive application of plant protection chemicals.
