Genetic diversity of Oenococcus oeni strains isolated from Yinchuan wine region in the East of Helan Mountain, China

Abstract

Aim: This study aimed to isolate Oenococcus oeni in red wines from Yinchuan wine region in the East of Helan Mountain, China, and analysis their genetic diversity.

Methods and Results: Oenococcus oeni strains were isolated from Cabernet Sauvignon and Cabernet Gernischt wines of four representative wineries in 2016. Total 207 O. oeni strains were isolated and identified by species-specific PCR. Following that, 206 amplified fragment length polymorphism (AFLP) genotypes were detected, with the similarity coefficients ranging between 63% – 97%. Based on the UPGMA, two major phylogroups were deciphered at 81% similarity level. Interestingly, the strains in different phylogroups were isolated from wines of different cultivars. In addition, strains from the same winery formed a unique cluster.

Conclusions: 

Our results indicate there is an obvious genetic relationship of O. oeni with grape cultivars and their origins. Our results also support the fact that O. oeni is an important factor related to the wine terroir. 

Significance and Impact of the Study: The Chinese wine industry has steadily grown in recent years. However, limited development and application of indigenous O. oeni strains would lead to homogeneity in wine quality. The outcome of this study would lay down the theoretical foundation for the development of indigenous O. oeni strains with regional characteristics.

Where the sky is no limit — The transformation of wine marketing through text-to-video generation AI model

The introduction of ai-driven tools in digital content creation represents a significant shift in the landscape of marketing, particularly for industries reliant on rich visual storytelling such as the wine sector. The development of ai models like openai’s sora, runway’s gen-2 or google’s lumiere, which can generate realistic video content from textual descriptions, offers promising new avenues for enhancing brand narrative and consumer engagement. This research explores the potential of text-to-video (t2v) ai models to revolutionize wine marketing by creating dynamic, engaging content that captures the essence of vineyards and their products without the need for traditional video production processes.

Study of wine-growing land (“terroir”) characteristics in the canton of Vaud (Switzerland): ecophysiological behaviour of the vine (cv. Chasselas)

A study of the physiological and agronomical behaviour of the vine (cv. Chasselas) was conducted between 2001 and 2003 by the Swiss Federal Research Station for Plant Production at Changins (Agroscope RAC Changins) on various wine-growing farms (terroirs) in the Canton of Vaud (Switzerland), as part of a study project on Vaudois

Potentiel des sols viticoles et qualité des vins

La qualité des vins dépend de différents facteurs et procédés, notamment de la nature des terrains viticoles. Dans ce travail, nous avons cherché à établir les liens entre descripteurs pédologiques des parcelles et descripteurs sensoriels des vins. Sur la base de Classifications Ascendantes Hiérarchiques (CAH) et d’Analyses en Composante Principale (ACP), il a été possible d’établir des liens entre la nature des parcelles (sableuse, argileuse, sablo-graveuleuse) et certains descripteurs sensoriels des vins (chaleur, astringence, fruit noir) et plus globalement avec le type de vins élaborés.
