Tackling the 3D root system architecture of grapevines: a new phenotyping pipeline based on photogrammetry

Abstract

Plant roots fulfil important functions as they are responsible for the acquisition of water and nutrients, for anchorage and stability, for interaction with symbionts and, in some cases, for the storage of carbohydrates. These functions are associated with the Root System Architecture (RSA, i.e. the form and the spatial arrangement of the roots in the soil). The RSA results from several biological processes (elongation, ramification, mortality…) genetically determined but with high structural plasticity. In grapevine, several factors can influence the RSA development (e.g. rootstock and scion genotypes, soil and plant management…). However, the effects of all these factors on the establishment of the RSA and associated functions (e.g. drought tolerance) have hardly ever been assessed. Such an assessment could help to improve the management of vineyards in our changing world. This lack of knowledge is mainly associated to methodological difficulties to characterize the RSA during grapevine development in the vineyard. To take up this challenge, we developed a new phenotyping pipeline, connecting photogrammetric data (produced by ArcheovisionProduction) with plant structures reconstruction software (PlantScan3D) and two packages dedicated to plant architecture analysis and visualisation (MTG and PlantGL from the OpenAlea platform). This new approach was developed on the uprooted root systems of two perennial species: grapevine and maritime pine. Their robustness was evaluated by comparing root traits estimated by this pipeline to root traits measured manually or estimated by a reference technique (semi-automated 3D digitizing, used on maritime pine root systems [1]). With this pipeline, we have planned to characterize the RSA of different rootstock genotypes, from different plantation types, soil management or water treatments, and at several developmental stages. All these data will be used to calibrate a functional-structural root model to facilitate the selection of plant material aimed to overcome the negative effects of climate change.

New oenological criteria for selecting strains of Lachancea thermotolerans for wine technology

The study conducted various fermentations of different grape juices using various strains of Lachancea thermotolerans and one strain of Saccharomyces cerevisiae. Because of the new conditions caused by climate change, wine acidity must be influenced as well as the volatile profile. Non-Saccharomyces yeasts such as L. thermotolerans are real options to mitigate the impact of climate change in wine production.

Comparison of the effects of hormone- and natural-based elicitors on key metabolic pathways in cv. Tempranillo

One of the most important effects of climate change in wine-growing areas is the advance of phenological stages, especially concerning early berry ripening. In the hottest seasons, this results in a lack of synchrony between sugar and phenolic ripeness. In order to cope with this fact, a general effort is being made by researchers and growers aiming at delaying ripening through different strategies. One of the proposed approaches is the application of elicitors. This study aims to assess the effect at the transcriptomic level of application of three elicitors (Vitalfit, Fruitel, and Protone) in Tempranillo.

Association between dietary pattern and wine consumption and Alzheimer’s disease in a cohort from La Rioja (Spain)

Addressing modifiable risk factors is the most promising strategy to prevent/delay Alzheimer Disease (AD)[1]. The aim of the study was to establish the connections between dietetic habits, wine consumption and AD. Thus, 98 volunteers were recruited: 50 diagnosed as AD and 48 healthy/controls. The Food Frequency Questionnaire (FFQ) was used for dietary patterns assessment and, based on these data, the Mind Diet Score was calculated. (Poly)phenol metabolites (especially derived from wine consumption) were analyzed by UPLC-QqQ-MS/MS in 24-h urine samples to confirm dietary (poly)phenol consumption.

Identification of a stable epi-allele associated with flower development and low bunch compactness in a somatic variant of Tempranillo Tinto

Grapevine cultivars are vegetatively propagated to preserve their varietal characteristics. However, spontaneous somatic variations that occur and are maintained during cycles of vegetative growth offer opportunities for the natural improvement of traditional grape cultivars. One advantageous trait for winegrowing is reduced bunch compactness, which decreases the susceptibility to pests and fungal diseases and favor an even berry ripening.

Long-lasting flavour perception of wines treated with oenological additives considering the individual PROP taste-phenotype

The use of oenological additives is becoming a common practice due to the technological and sensory properties they provide to the wines. However, the number of studies focused on the impact that these additives might induce on wine flavor perception during wine tasting is still quite scarce. The aim of this work was to evaluate the effect of three different types of common oenological additives: two oenotannins (ellagitannin and gallotannin) and a commercial preparation of yeast mannoproteins on the long-lasting flavor perception (aroma and astringency).
