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.

Isohydric and anisohydric behavior of 18 wine grape varieties grown in an arid climate

The interest in understanding the water balance of terrestrial plants under drought has led to the creation of the isohydric/anisohydric terminology. The classification was related to an implication-driven framework, where isohydric plants maintain a constant and high leaf water potential through an early and intense closure of their stomata, hence risking carbon starvation. In contrast, anisohydric plants drop their leaf water potential to low values as soil drought is establishing due to insensitive stomata and thus risk mortality through hydraulic failure, albeit maximizing carbon intake. When applied to grapevines, this framework has been elusive, yielding discrepancies in the classification of different wine grape varieties around the world.

In April 2024, the French official catalog includes 449 grape varieties and rootstocks. In 10 years it has been enriched with 70 varieties. It is an indisputable marker of the interest of professionals in genetic resources of all origins and the expectations they have to prepare the viticulture of the future. The scientific community has now put all irons in the fire and is not neglecting any avenue of adaptation. The regular decline in the use of phytosanitary products and the already marked effects of climate change are the targets of varietal improvement.

Bioprotective effect of a Torulaspora delbrueckii/Lachancea thermotolerans mixed inoculum and its impact on wines made.

SO2 is an additive widely used as antimicrobial in winemaking industry. However, this compound can negatively affect health, so the search for alternatives is currently a line of research of great interest. One of the proposed alternatives to SO2 as an antimicrobial is the use of bioprotection yeasts, which colonize the medium preventing the proliferation of undesirable microorganisms.
