Investigating the role of endophytes in enhancing grapevine resilience to drought

Abstract

Grapevine is a crop of great economic importance for several countries. The intensification of grapevine production has mostly been sustained by the increasing use of water resources at the expense of the environmental water balance. Moreover, in the last decades, climate change and the consequent expansion of drought have further compromised water availability, making current agricultural systems even more fragile both ecologically and economically. Recently, many research groups have highlighted the important role of endophytes in facilitating plant growth under optimal or stressful conditions. Within the framework of the PRIMA project, we aim to investigate the possible exploitation of the natural endophyte biodiversity as a sustainable tool to make grapevine plants more resilient to water deficit environmental conditions. Cultivable bacterial communities of field grapevine plants growing in the arid regions of Italy and Algeria have been isolated from leaf tissues. Endophytes were characterised and screened for their plant growth-promoting traits and used to generate endophyte consortia to inoculate endophyte-free grapevine plants. In a parallel approach we tested the possibility of using the grafting procedure to transfer endophytes between plants. Preliminary data are presented showing the efficiency of this procedure and the dynamics of the endophyte community in the destination plant.

Effects of Silver Thiosulphate and Salicylic Acid on the long-term maintenance of the embryogenic callus of Vitis vinifera

New Plant Breeding Techniques (NPBTs) have the potential to revolutionize the genetic improvement of grapevine. However, the practical application of these techniques is limited by several challenges, such as the difficulty in generating embryogenic calluses, maintaining their competence during in vitro cultivation, and regenerating plants without defects. To overcome these challenges, we conducted a study to test the effect of two treatments on callus cultures derived from different grapevine varieties, with and without embryogenic competence. The tested substances were Silver Thiosulphate (STS) an ethylene inhibitor, and Salicylic Acid (SA), an elicitor with different effects depending on the concentration of use beyond the ethylene inhibitor activity.

First insights on the intra-species diversity in V. berlandieri: environmental adaptation and agronomic performances when used as rootstock

In grafted plants, such as grapevine, increasing the diversity of rootstocks available to growers is an ideal strategy to get adaptation to climate change. The rootstocks used for grapevine are hybrids of various American Vitis, including V. berlandieri. The rootstocks currently used in vineyards are derived from breeding programs involving very small numbers of parental individuals.

Biological control of root phylloxera by Metarhizium brunneum–student projects at the Winecampus Neustadt

The potential use of Metarhizium brunneum to control root phylloxera was tested on potted vines in the green house in studentical projects at the Winecampus Neustadt. In 2023 Metarhizium was applied by inoculated barley and by suspension variant in single pot experiments on 5 BB rootstock vines artificially infested by root phylloxera.

Digital PCR: a tool for the early detection of brettanomyces in wine

Brettanomyces bruxellensis is found in various ecological niches, but particularly in fermentative processes: beer, kombucha, cider and wine. In the oenological sector, this yeast is undesirable, as it can produce ethyl phenols, thus altering wine quality. These compounds are characterized by stable or horse-sweat aromas, unpleasant for consumers.
