Digitalization and valorization of the genotypic and phenotypic information retained within the FEM grapevine germplasm

Abstract

The maintenance and valorization of genetic diversity is an undoubtable resource for the viticulture of the future, since the climate crisis is forcing us to think of new, more resilient varieties. For this reason, the grapevine germplasm of the Fondazione Edmund Mach has been continuously expanded in the last decade to a total of 3,120 accessions, whose trueness-to-type has been verified by means of the universal set of nine microsatellites. About two thirds are V. vinifera subsp. vinifera accessions, while the rest consists of naturalized and selected hybrids, V. vinifera subsp. sylvestris, and pure species. The genetic material has also been characterized over three consecutive years for ampelographic, vine development, and biotic stress response traits to be exploited for experimental purposes. All the data and metadata have been digitalized and hosted in a SQL database, the FEMVitisDB, developed with an ontology driven paradigm to annotate the deposited information. The database was built following the MIAPPE checklist to ensure data FAIRness. A RESTful WebServiceAPI based on BrAPI and a web frontend were developed to easily explore the information in the repository.
Findings about the captured genetic diversity, the identified unique profiles, and the scouted unknown and therefore novel genotypes will be discussed. The latter enrich the genetic asset of the grapevine community, towards the feeding of international databases. Where feasible, the first degree of parentage relationship has been reconstructed. Finally, the outcomes regarding the inferred phenological core collections will be introduced to provide an information arsenal for future ’omics analyses.

Flor yeast diversity and dynamics in biologically aged wines

Wine biological aging is characterized by the development of yeast strains that form a biofilm on the wine surface after alcoholic fermentation. These yeasts, known as flor yeasts, form a velum that protects the wine from oxidation during aging. Thirty-nine velums aged from 1 to 6 years were sampled from “Vin jaune” from two different cellars. We show for the first time that these velums possess various aspects in term of color and surface aspects. Surprisingly, the heterogeneous velums are mostly composed of one species, S. cerevisiae. Scanning electron microscope observations of these velums revealed unprecedented biofilm structures and various yeast morphologies formed by the sole S. cerevisiae species.

Screening of hydroxytyrosol and tyrosine related metabolites in commercial wines by an UHPLC/MS validated method.

Hydroxytyrosol (HT) is a bioactive phenolic compound with antioxidant activity. Yeast synthetise tyrosol from tyrosine by the Ehrlich pathway which is subsequently hydroxylated to HT. The aim of the present work is to develop and validate an UHPLC–HRMS method to assess the metabolites involved in this pathway as well as to screen Spanish commercial wines for HT bioactive compound.

Dual mode of action of grape cane extracts against Botrytis cinerea

Crude extracts of Vitis vinifera canes represent a natural source of stilbene compounds with well characterized antifungals properties. In our trials, exogenous application of a stilbene extract (SE) obtained from grape canes on grapevine leaves reduces the necrotic lesions caused by Botrytis cinerea
