<p>Vitis vinifera L. cultivar “Cannonau” (Magnoliopsida Vitaceae) has been grown for years in the Italian regions to produce a fine wine, with Controlled Designation of Origin (DOC) and Denomination of Controlled and Guaranteed Origin, (DOCG). The International Organization of Vine and Wine (OIV) defined the “terroir” as “a concept which refers to a specific area in which the interactions between the physical and biological environment and applied vitivinicultural practices develops. Whereas, from a geological point of view, the terroir has been defined as the geochemistry of soil, surface and ground water. Recent studies, regarding vitis vinifera, based on geochemical characterization have clearly shown the connection among geological origin, vineyard soil and grape berries. Another way to trace geographical origin can be through the identification of Rare Earth Elements (REEs) in the soil-plant system. However, the study of REEs is also important to define the petrological characterization and the relations between soil and plants.</p><p>We evaluated the relationship among the concentrations of rare earth elements (REE) in soil and in “Cannonau” grape berries in vineyards belonging to two different vineyards located in the valleys Pardu and Pelau in Sardinia (Italy) and one in Susegana in the Veneto Region (Northern Italy). The concentration of REE in samples of soil and juice or solid residues of grape berries was determined by inductively coupled plasma mass spectrometry (ICP-MS) and the data were elaborated with multivariate statistics (Linear Discrimination Analysis).The concentration of REEs in soil and grape berry samples allowed an identification of each locality examined . Moreover, the geochemical and statistical analyses allowed to discriminate the vineyard soils and grape berries according to geo-lithological characteristics of each area and to identify possible geochemical markers for the cultivar “Cannonau” .These markers, suitable as terroir fingerprintings, may be useful to avoid fraudulent use of the denomination label and falsification of the Made in Italy trademark.</p>

The molecular regulation of stilbene phytoalexin biosynthesis in developing Vitis vinifera L. grape berries was investigated using a UV induction system. Berries were collected at 1, 5, 10 and 16 weeks post-flowering from the cultivars Shiraz, Semillon, Cabernet Sauvignon and Chardonnay and the skins analysed for resveratrol production following irradiation with UV-C light. The rate and maximal level of resveratrol accumulation increased markedly in berries sampled from 1–5 weeks post-flowering and then dramatically declined in maturing berries sampled from 10–16 weeks post-flowering in all cultivars. In berries sampled at 1 and 5 weeks post-flowering, maximal levels of resveratrol accumulation were recorded at incubation periods of 24 and 48 h respectively whereas maximal resveratrol levels were not recorded in week 16 berry skins until 72 h after UV-treatment. Gene expression analysis indicated that stilbene synthase (STS) mRNA accumulated within 4–8 h of UV treatment in berries sampled at 1 and 5 weeks post-flowering, but did not increase in week 16 berries until 24–48 h following UV-irradiation. Furthermore, the overall level of STS gene expression declined in berries sampled 10–16 weeks post-flowering. The results demonstrate that inducible stilbene accumulation in ripening grape berries is highly regulated at the level of STS gene transcription. This decline in inducible STS gene expression may be a major factor contributing to the increased susceptibility of ripening grape berries to Botrytis cinerea infection.

<p>Rare Earth Elements (REE) have been employed to stimulate the plant growth in national and international strategies while their role still remains controversial as the process involved in soil-plant system is not completely understood yet.  </p><p>In this study we have investigated the effect of REE amount in the substrate during the Vitis vinifera L growth analysing the REE distribution in the different part of the plants. Experiments were carried out over 1 year using two different substrates: one with a "natural" substrate (blank experiments) and another using the same substrate artificially enriched by an equimolar solution of REE (spiked experiments).</p><p>We found that both plant mass and amount of REE in leaves are both not influenced by the substrate enrichment. However, roots are by 1 order of magnitude enriched in REE for the 3 orders of magnitude enriched substrate of growth. This indicates that Vitis vinifera L. does not significantly transfer REE into the aerial parts during growth while identify roots as the plant critical parts responsible for the filtering of the environmental stress.  Plotting the REE normalized distribution for every element, the different experimental conditions can be significantly discriminated: under spiked substrate conditions, REE normalised distribution shows a ‘zig zag’ pattern in both leaves and roots. We propose that the REE normalised distribution pattern measured in the different plant parts (leaves and roots) can be used to discriminates the conditions of substrate characteristics during the vitis vinifera growth. Acting as natural tracers, the REE normalised distribution could be potentially used as tool tracing the substrate origin of the Vitis vinifera plant. </p>

<p>The present contribution reports the results from a geochemical and statistical study aimed to identify in the Rare Earth Elements (REEs) absorption a good fingerprinting marks for determining the territoriality and the provenance of Vitis vinifera L. into two different geological contexts in Sicily: the volcanic district of Mount Etna and the carbonate platform of the Hyblean Plateau (Sicily, southern Italy). Our aim was to: i) define if the REEs  distribution in plants may reflect the composition of the provenance soil under similar climate conditions; ii) highlight differences, if any, in REE absorption within the various parts of the plants; and  iii) propose, for selected cultivar of Vitis vinifera L., a REE fingerprint in the Etna Volcano and Hyblean carbonate soils as well as to recognize characteristic REEs pattern.</p><p>To this aim, REE content has been determined by ICP-MS investigation in the soils and in the selected grapevine varieties for all the following parts: leaves, seeds, juice, skin and berries. Geochemical data have also been approached by a multivariate statistical analysis of the Principal Component Analysis (PCA), together with the Linear Discriminant Analysis (LDA).</p><p>The work permitted to highlight various REE distribution within the various parts of the plant and assessed as each grape variety presents a characteristic geochemical pattern in the absorption of REEs in relationship with the geochemical features of the type of soil on which the grapes grew.</p>
