Using nanopore skim-sequencing to characterise regional epigenetic variability in New Zealand Sauvignon Blanc

The selection of ancient grapevine varieties aims to achieve genetic gains in several important traits that can make the variety more interesting for the objectives of the producers. Traditionally, yield and quality traits of the must have been considered for selection, but many others can be taken into account. Linear mixed models are fitted to the data to predict the empirical best linear unbiased predictors (EBLUPs) of genotypic effects for each evaluated trait, which will be the basis for selection.

Rare Earth Elements (REEs) include 15 lanthanides, yttrium and scandium. Their occurrence in soil and plants seems to be closely tied to the geological composition of the underlying mother rock, to the physical and chemical properties of the soil and to the specific ability of the plant to take up and accumulate these microelements.

The market share of Rosé wine in France has grown from 11 % to 32 % over the last 20 years. Current trends are towards rosé wines of a lighter shade of pink, and where possible, containing a greater concentration in varietal thiols. Grape varieties, the soil on which they are grown, viticultural practices and winemaking technology all impact the polyphenols, color and aromas of rosé wines.

The ambition of the zonation of the Doc “Sangiovese di Romagna” is described as 25 siti sperimentali, aventi diversa origine geologica, in cui è stato individuato un vigneto omogeneo per la determinazione dei principali parametri viticoli ed enologici. In seguito è stato analizzato il contentto di stilbeni nei vini al fine di indepth il legame con le charatteristiche geopedologiche. The studio describes the positive relationship between the altitude and the content of the trans -piceide nelle province di Forlì and Ravenna and of the trans -resveratrolo a Ravenna. I suoli con maggiore calcare attivo hanno fornito vini più ricchi in stilbeni.

Actually, many countries around the world are studying different strategies for adapting winegrowing regions to climate changes, focusing on a sustainable viticulture.
