Uncovering the genetic basis of agronomic traits in over 1,000 grapevine genotypes derived from a disease resistance breeding program Open
European viticulture faces two critical challenges currently: climate change and its direct and indirect impacts in the one hand and the need to dramatically reduce pesticide use in the other hand. In response, breeding programs, such as t…

Metabolic biomarker-based phenotyping unveils quantitative effects of plant resistance and pathogen aggressiveness in the grapevine (Vitis spp.) - downy mildew (Plasmopara viticola) pathosystem Open
Grapevine resistance to downy mildew has been primarily associated with major “Resistance to Plasmopara viticola ” ( Rpv ) loci, which are extensively used in breeding programs. Resistant varieties represent an effective solution to mitiga…

Impact of the introgression of resistance loci on agro-œnological traits in grapevine interspecific hybrids Open
Summary A major aim in modern grapevine ( Vitis vinifera L.) breeding programs is the introgression of disease resistance genes along with desired cultural and œnological traits. Understanding the genetic links between resistance genes and…

Quelques pistes pour l'étude des situations d'informatique débranchée Open
Computer science unplugged is a scientific popularization project initiated in the 1990s by a team of New Zealand researchers. It enables participants to discover the major concepts of computer science, without a computer, through physical…

Partition strategies for the Maker-Breaker domination game Open
The Maker-Breaker domination game is a positional game played on a graph by two players called Dominator and Staller. The players alternately select a vertex of the graph that has not yet been chosen. Dominator wins if at some point the ve…

The grapevine QTLome is ripe: QTL survey, databasing, and first applications Open
Overarching surveys of QTL (Quantitative Trait Loci) studies in both model plants and staple crops have facilitated the access to information and boosted the impact of existing data on plant improvement activities. Today, the grapevine com…

Genetic determinism of grapevine development stages as a tool for the adaptation to climate change Open
A major goal of modern grapevine (Vitis vinifera L.) breeding programs is the introgression of resistance genes along with desirable traits for better adaptation to climate change. Developmental stages have an impact on yield components an…

Phenotyping grapevine resistance to downy mildew: deep learning as a promising tool to assess sporulation and necrosis Open
Background Downy mildew is a plant disease that affects all cultivated European grapevine varieties. The disease is caused by the oomycete Plasmopara viticola . The current strategy to control this threat relies on repeated applications of…

A test-tube vinification method for high-throughput characterisation of the oenological and aromatic potential of white wines Open
The quality of wine largely depends on aroma perception, but the genetic basis explaining the variations of aroma compound concentrations in wines is still fragmentary. To unravel links between genetic variations and aroma compound variati…

Moving towards grapevine genotypes better adapted to abiotic constraints Open
Vitis spp., both in their cultivated and wild forms, have been growing in a large diversity of environments for thousands of years. As a result, they have developed many adaptive mechanisms controlled by a range of regulatory processes. Th…

MYB24 orchestrates terpene and flavonol metabolism as light responses to anthocyanin depletion in variegated grape berries Open
Variegation is a rare type of mosaicism not fully studied in plants, especially fruits. We examined red and white sections of grape (Vitis vinifera cv. ‘Béquignol’) variegated berries and found that accumulation of products from branches o…

The Maker-Maker domination game in forests Open
We study the Maker-Maker version of the domination game introduced in 2018 by Duchêne et al. Given a graph, two players alternately claim vertices. The first player to claim a dominating set of the graph wins. As the Maker-Breaker version,…

Sustaining wine identity through intra-varietal diversification Open
To sustain local wine identity in uncertain climate outcomes, the study of intra-varietal diversity is important to reflect the adaptive potential of cultivated varieties. Findings highlight the strong phenotypic diversity of studied varie…

An improved reference of the grapevine genome reasserts the origin of the PN40024 highly homozygous genotype Open
The genome sequence of the diploid and highly homozygous Vitis vinifera genotype PN40024 serves as the reference for many grapevine studies. Despite several improvements to the PN40024 genome assembly, its current version PN12X.v2 is quite…

Complexity of Maker-Breaker Games on Edge Sets of Graphs Open
We study the algorithmic complexity of Maker-Breaker games played on the edge sets of general graphs. We mainly consider the perfect matching game and the $H$-game. Maker wins if she claims the edges of a perfect matching in the first, and…
