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.

High-throughput screening of physical-mechanical berry skin traits facilitates targeted selection of breeding material with resistance to Botrytis bunch rot and grape sunburn

The ongoing climate change implies an increasing mean air temperature, which is signified by weather extremes or sudden changes between drought and local heavy rainfalls. These changing conditions are especially challenging for the established grapevine varieties growing under cool climate conditions due to an increased risk for fungal diseases like downy mildew (DM) and Botrytis bunch rot (BBR) as well as for grape sunburn. To meet that demand, the scope of most grapevine breeding programs is the selection of mildew fungus-resistant and climatic adapted grapevines with balanced, healthy yield and outstanding wine quality.

Yeast mannoprotein characterization and their effect on Oenococcus oeni and malolactic fermentation

Mannoproteins are released at the end of alcoholic fermentation due to yeast autolysis [1]. It has been described a positive effect of these molecules on lactic acid bacteria growth [2]. The main objective of this work was the characterization of different mannoproteins extracted from active dry yeast (ADY) and the assessment of their effect on Oenococcus oeni and malolactic fermentation (MLF).

Genetic prospecting of rainfed viticulture in the region with the largest cultivated area in Chile

The Maule region hosts up to a third of the total area of vineyards in Chile, in an environment where ancient practices inherited from the colonial past coexist with modernity and dynamism that include technified irrigation and fine vines. In the dry land of Maule there is a viticulture that has subsisted with ancient vines and traditions transmitted over generations, and there is little clarity about the origin and classification of the Maule viticulture, giving rise to the use of different concepts as synonyms to describe the ancient, minority, patrimonial or Criollas vines. In order to characterize and protect the ancient material, we studied the genetic diversity of a territorial collection that covers 80% of the communes of the region, prioritizing plants established more than 40-60 years ago.

Discovering the process of noble rot: fungal ecology of grape berries during the noble rot transformation in different vineyards of the Tokaj wine region

Botrytis cinerea, a well-known grapevine pathogen, has more than 1200 host plants causing grey rot in grapevine berries. However, it can also result in a desirable phenomenon called noble rot under specific microclimate conditions. An extraordinary demonstration of this natural process can be observed in the creation of aszú wines within Hungary’s Tokaj wine region. Beside B. cinerea other fungi and yeasts are involved in the secondary metabolic development of the grape berry which contributes to the sensory and analytical characterization of noble rot wines.

Polysaccharide families of lyophilized extracts obtained from unfermented varietal grape pomaces

The recovery of bioactive compounds from grape and wine by-products is currently an important objective for revaluation and sustainability. Grape pomace is one of the main by-products and is a rich source of some bioactive compounds. The aim of this study was to evaluate the polysaccharide (PS) composition of extracts obtained from pomaces of different white and red grape varieties of Castilla y León. Grape pomaces were obtained after the pressing in the winemaking process.
