Il paesaggio delle alberate aversane ed il vino Asprinio

Abstract

[English version below]

Nel corso del 2009, in alcuni vigneti allevati ad alberata in provincia di Caserta (Italia), è stata avviata una ricerca per valutare la variabilità genetica della popolazione del vitigno ‘Asprinio’, la condizione sanitaria delle piante e le caratteristiche del vino sia rispetto alla forma di allevamento (alberata tradizionale e controspalliera) che all’altezza della fascia produttiva. I primi risultati indicano la totale omogeneità genetica della popolazione del vitigno ‘Asprinio’, non essendo stati ritrovati campioni vegetali riferibili a biotipi diversi. I saggi immunoenzimatici ELISA hanno rilevato la presenza di GLRaV 1, GLRaV 3 e GVA in tutti i campioni, mentre l’analisi delle molecole aromatiche delle uve e dei vini, condotta mediante analisi SPME-GC/MS, ha messo in evidenza che le uve ‘Asprinio’, prodotte sulla fascia più bassa delle alberate, presentano una maggiore potenzialità aromatica, rispetto a quelle della fascia più alta o delle controspalliere. I vini prodotti con diversi protocolli mostrano parametri enologici (grado alcolico, livelli di pH a acidità totale) simili tra di loro ed a quelli riportati da autori della metà del XX secolo.

During 2009, in some vineyards grown on trees (alberata) in the province of Caserta (Italy), a study is carried out to assess the genetic variability of the ‘Asprinio’ grapevine population, the health condition of the plants and the features of the wine in relation to the breeding system (traditional alberata vs horizontal training system) and to the heigth of fertile shoots. The first results point out the genetic identity of the ‘Aprinio’ grapevine population, because no different bio-types were found. The immunoenzymatic essays ELISA revealed that all the accessions were infected by GLRaV 1, GLRaV 3 and GVA; whereas the determination of the aromatic molecules from grapes and wines, performed by SPME- GC/MS analysis, indicated that the ‘Asprinio’ grapes, grown on lower area of the alberata, show greater aromatic potential than those from highest level of the same or those from vertical training system. The wines, produced by different procedures, show oenologycal parameters (alcohol degree, pH and total acidity level) similar to each other and to those reported by some authors of the mid-twentieth century.

Saccharomyces cerevisiae – Oenococcus oeni – Lactiplantibacillus plantarum: focus on malolactic fermentation during production of Catarratto and Riesling white wines

The increasing interest in enhancing groundbreaking sensory profile of wines determined the need to select novel strains of lactic acid bacteria (LAB). Metabolic processes characterizing malolactic fermentation (MLF) lead to the production of several organic compounds that significantly impact the oenological and sensory characteristics of wines.

Study of the interactions between wine anthocyanins and proline rich proteins

The interaction between tannins and salivary proteins is considered to be the basis of the phenomenon of wine astringency. Recently, some authors have revealed that some anthocyanins can also contribute to this mouthfeel sensation by interacting with proline rich proteins (PRPs). However, more studies are needed in order to elucidate the affinity of anthocyanins with these proteins.

Genomic characterization of terpene biosynthetic genes in seven Vitis vinifera L. varieties 

Grapes (Vitis vinifera L.) are a fruit crop of high economic significance globally. Each grapevine cultivar is characterized by its distinctive grape aroma, affecting the wine quality. In several cultivars, the aroma is shaped by terpenoid (mono- and sesqui-terpenoids). Their profile is controlled by terpene synthases (TPS), which are part of a largely expanded gene family. How the variation in TPS copy number and sequence among cultivars determines terpenoid profiles of grapes remains largely unexplored. We annotated TPS in the haplotypes of seven genomes (Riesling, Albariño, Fiano, Gewürztraminer, Pinot Noir, Cabernet Sauvignon, and Viognier) using BLAST, GMAP, PFAM, and phylogenetic analyses. Further, TPS expression patterns and terpenoid accumulation during berry development and ripening were characterized using RNA-Seq and SPME/GC-MS platforms, respectively. Variation in TPS copy number exists among cultivars. Specifically, the TPS counts span a range of 251 to 150 for Riesling and Fiano, respectively, when considering combined haplotypes within each cultivar. Total terpenoid accumulation patterns throughout development were consistent among the five aromatic cultivars, marked by high concentrations in flowers, followed by a decline and subsequent rise during berry development and ripening, respectively. Conversely, non-aromatic cultivars exhibited no substantial increase in terpenoid concentration during ripening. Transcriptome and network analyses are currently employed to determine which TPS are expressed in the berry and determine the terpenoid profile of the specific cultivar. These findings shed light on the genomic determinants of grape aroma in major cultivars, and allow future studies focused on cultivar-specific responses of terpenoid biosynthesis to environmental stresses.
