Optimizing protocol for a rapid and cost effective DNA isolation for Marker Assisted Selection pipeline

Abstract

Grapevine is a plant that holds significant socioeconomic importance due to its production of grapes for fresh consumption, wines, and juices. However, climate changes and susceptibility to diseases pose a threat to the quality and yield of these products. The breeding of new genotypes that are resistant/tolerant to biotic and abiotic stresses is essential to overcome the impact of climate changes. In this regard, Marker-assisted selection (MAS), which uses DNA markers, is a crucial tool in breeding programs. The efficiency and economy of this method depend on finding rapid DNA isolation methods. In this study, we compared four different DNA extraction methods to choose the one that quickly isolates DNA from many young vine leaves samples in a single run. The methods used involved Lithium chloride, carboxyl coated magnetic beads, cetyltrimethylammonium bromide (CTAB), and a commercial kit called Red&extract. The results showed that the CTAB method was the best in terms of reliability of the procedure, yield of the extracted DNA, low quantity of inhibitors, and speed of the procedure. Improving the MAS technique will help identify plants containing genes involved in different types of stress and deepen the study of the resistance genes pyramided.

OENOLOGICAL POTENTIAL OF AUTOCHTHONOUS SACCHAROMYCES CEREVISIAE STRAINS AND THEIR EFFECT ON THE PRODUCTION OF TYPICAL SAVATIANO WINES

Due to the global demand for terroir wines, the winemaking industry has focused attention on exploiting the local yeast microflora of each wine growing region to express the regional character and enhance the sensory profile of wines such as varietal typicity and aroma complexity. The objective of the present study was to isolate and compare the indigenous strains of Saccharomyces cerevisiae present in different vineyards in the Mesogeia – Attiki wine region (Greece), evaluate their impact on chemical composition and sensory profile of Savatiano wines and select the most suitable ones for winemaking process.

Influence de l’ensoleillement sur la composante aromatique des baies de raisin

Syrah is a grape with weak aromatic expression. This atypical grape variety as a fruit allows the production of wines of great reputation for which the aromatic particularity plays an important role. The varietal aroma consists of volatile substances directly perceptible by the olfactory mucosa and of aroma precursors, of which the glycosides constitute an important class.

High density balsamic vinegar: application of stable isotope ratio analysis to determine watering down.

Aceto balsamico di Modena IGP (ABM) is an Italian worldwide appreciated PGI (Protected Geographical Indication) vinegar,  obtained from cooked and/or concentrated grape must (at least 20% of the volume), with the addition of at least 10% of wine vinegar and a maximum 2% of caramel for color stability (EU Reg. 583/ 2009).

Quantification of newly identified C8 aroma compounds in musts and wines as an analytical tool for the early detection of Fresh Mushroom Off-Flavor

The Fresh Mushroom Off-Flavor (FMOff) is a concerning undesirable aroma in wine specific of certain vintages, characterized by a typical button mushroom aroma. The appearance of this off-flavor is linked to the presence of certain fungus on the grape [1-3].

Reaction Mechanisms of Copper and Iron with Hydrogen Sulfide and Thiols in Model Wine

Fermentation derived sulfidic off-odors due to hydrogen sulfide (H2S) and low molecular weight thiols are commonly encountered in wine production and removed by Cu(II) fining. However, the mechanism underlying Cu(II) fining remains poorly understood, and generally results in increased Cu concentration that lead to deleterious reactions in finished wine. The present study describes a mechanistic investigation of the iron and copper mediated reaction of H2S, cysteine, 3-sulfanylhexan-1-ol, and 6-sulfanylhexan-1-ol with oxygen. The concentrations of H2S, thiols, oxygen, and acetaldehyde were monitored over time. It was found that Cu(II) was rapidly reduced by both H2S and thiols to Cu(I).
