In vitro regeneration of grapevine cv. Aglianico via somatic embryogenesis: preliminary studies for next genome editing applications  

A fair and sustainable society, with a modern, resource-efficient and competitive economy cannot be achieved without a workforce to support it.

According to the algorithm “A step back towards the future 4.1C”, (Cargnello,1986a, 1987d, 1988a.b, 1991, 1993, 1994b, 1995, 1999a.e, 2000b, 2007c, 2008a, 2009d, 2013; and according to the principles of “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” of GiESCO (Carbonneau and Cargnello, 2003 2015, 2017), the historical, applied philosophy and productive analysis connected to the innovations and to the “Certification of the Universal Holistic MetaEthical Sustainability 4.1C” “indexed new global production model 4.1C” has always been fundamental, especially for the “Prosecco Territory” and for the “Prosecco Wine” to design and implement their synergistic future “Sustainable and Certificable 4.1CC” according to the principles of the “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” by the GiESCO (Carbonneau and Cargnello, lc, Cargnello et Carbonneau, 2007, 2018), and of the Conegliano Campus 5.1C. (Cargnello, lc). Nowadays, people think that Prosecco is a wine from the Veneto Region (from Conegliano and Valdobbiadene in particular), while it comes from Friuli‐Venezia Giulia Region (in North Eastern Italy, such as Veneto) more precisely from “Prosecco” in the Municipality of Trieste (TS‐Italy), as documented in 1382 and in 1548, when Pier Andrea Mattioli, described “that ancient wine, which is born in Prosecco”, as a wine with the following characteristics “thin, clear, shiny, golden, odorous and pleasant to taste». In 1888 at the “Wine Fair” of Trieste there were the “Sparkling wine Prosecco” by Giovanni Balanc, by Giuseppe Klampferer and that one by Marino Luxa. In the 19th century, many expressed their appreciation for the “Prosecco” of Trieste. In order to implement intra and extra territorial and cross‐border relations, as well as, the “Certification of: Products, Companies, Territory, Bio‐MétaÉthique District 4.1C” of Prosecco, a series of activities and researches were conducted in 8 companies: 5 in the “Territory of Prosecco” (TS) in which the principles of “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” of GiESCO (Carbonneau and Cargnello, lc) have been successfully applied. In particolar: 1‐ new and original “Sustainable 4.1C global production model” developed also to prevent the problems caused by wild boar, roe deer, and birds while safeguarding their “psychophysical wellness”, as well as the “psychophysical wellness 4.1C” of the macro and micro flora and fauna, of the biodiversity, of the landscape, etc. (Cargnello, lc), 1.2‐ chemical weed control and “Non MetaEthics 4.1C” processing with the total grass growing of the ground without or with mowing, better if it is manual to protect grass, air and soil, 2‐ recovery of “Historic”: land, vineyards, vines, biodiversity, landscapes, productions, products, … , 3‐ production of the famous “Prosekar, also rosé, of Prosecco” and “Prosecco di Prosecco”, according to “A step back towards the future 4.1C” 4‐ to offer a deserved psychophysical well‐being to the “Prosecco Territory” and entrepreneurs. 

The overall quality of fine wines is linked to the development of “bouquet” during wine bottle ageing (1). Bordeaux red wine ageing bouquet is defined by the association of several odours

In a collective marketing strategy, the Protected Designation of Origin (PDO) can be used as a quality indicator. To highlight terroir specificities, it is useful to know how the wines are positioned on the local, national or international market from a sensory point of view. This is especially true for a comparison of varietal wines (e.g. Sauvignon blanc). We focus on the case of two closed Loire Valley PDO (France): Quincy and Reuilly. Three distinct tastings were organized. Firstly, at the local level comparing the 2 PDO (11 and 9 wines, 17 professional assessors); secondly at a regional level adding 3 closed PDO: Menetou-Salon, Sancerre and Pouilly-Fumé (3 wines per PDO, 16 assessors) and thirdly at an international level comparing these 5 PDO with Sauvignon Blanc wines coming from South Africa, New Zealand and Chile (1 to 3 wines per PDO, 19 assessors). All the wines were from the 2019 vintage and were considered to have a traditional elaboration process without contact with oak. A sensory descriptive analysis was performed using an aroma wheel allowing to combine a Check-All-That-Apply methodology, often used in sensory benchmarking, with a hierarchical structuration of the attributes. The aim is to facilitate data acquisition in a professional context without common training, to consider the hierarchical relationships among the attributes during the data analysis and to be able to characterize wines with a large range of sensorial variability. We use univariate, multivariate and clustering analyses. Similarities and differences between Quincy and Reuilly PDO wines and other Sauvignon blanc wines were identified. Specific attributes can distinguish the two PDO and different proximities exist with other local PDO, while clear differences were observed compared to international wines. Our study contributes to propose and discuss a method to do a wine sensory benchmarking highlighting sensory specificities linked to origin.

The main objective of this work is to study and model the impact of the polyphenolic profile on the stability and quality of wine aroma during oxidative aging.
