Exploring the inner secrets of grapevine: a journey through plant-microbe interactions

Abstract

Throughout centuries of anthropocentric breeding, plants have been selectively bred to enhance their quality traits and yield, often overlooking the importance of neglected attributes, like those involved in the interactions with beneficial microorganisms. This phenomenon led to an alteration in the distribution of photosynthetic products, shifting from defence mechanisms to growth, commonly described as ‘domestication syndrome’. Addressing the losses stemming from this condition is imperative just as unravelling the concealed communication between grapevines and beneficial microorganisms. To this aim, a Synthetic Community (SynCom) has been formulated, using grapevine endophytes and arbuscular mycorrhizal fungi, and  applied to potted cuttings of diverse rootstock genotypes. Plant development and physiological parameters were carefully monitored throughout an entire growing season. Root samples were collected for: i) DNA extraction and metabarcoding analysis to identify the root-associated microbiota and ii) RNA extraction for transcriptomic analysis. Concurrently, leaf and root samples were collected for targeted metabolomics, focusing on compounds involved in microbial recruitment, including, among others, coumarins, strigolactones, salicylic acid, and jasmonic acid.

Employing an innovative multi-omics approach, phenotypic, physiological, biochemical, and molecular data will be integrated to improve our understanding of the complex interaction within grapevine and its associated microbiota.This could result in new breeding programs which will also consider these traits as selection criteria, thereby preserving the ability of grapevine to recruit beneficial microorganisms. Furthermore, these results will provide useful information for the development of a more effective SynCom to augment holobiont resilience and thus to promote more sustainable agricultural practices.

Mesoclimate impact on Tannat in the Atlantic terroir of Uruguay

The study of climate is relevant as an element conditioning the typicity of a product, its quality and sustainability over the years. The grapevine development and growth and the final grape and wine composition are closely related to temperature, while climate components vary at mesoscale according to topography and/or proximity to large bodies of water. The objective of this work is to assess the mesoclimate of the Atlantic region of Uruguay and to determine the effect of topography and the ocean on temperature and consequently on Tannat grapevine behavior.

Environmental sustainability in the production of grappa with the use of mould-resistant grape varieties: the aroma characterisation of distillates

Grappa is the most important italian spirit and its production includes elements of history, tradition, and culture of the transalpine country. In accordance with EU laws, grappa is obtained from the fermentation and distillation of the pomace, eventually added with fermentation lees and water. Grappa is one of the richest fruit distillates in volatile compounds that confer to the product its characteristic flagrance. The aroma is largely due to the volatile compounds present in the raw materials, in particular alcohols, esters and carbonyl compounds formed during the alcoholic fermentation, but also to grape aromas such as terpenols and norisoprenoids, that confers grappa the distinctive floral scents.
