Plastid genomics of Vitis vinifera L. for understanding the molecular basis of  grapevine (Vitis vinifera L.) domestication

Abstract

Over the past decade, numerous scientific studies have utilized advanced next-generation plastid DNA technologies to assess the genetic diversity of grapevine (Vitis vinifera L.) worldwide, aiming for a deeper understanding the possible molecular mechanisms of domestication process. For such studies, it is essential to include both cultivated varieties (Vitis vinifera subsp. vinifera) and their wild ancestors (Vitis vinifera subsp. sylvestris) from all potential distribution and domestication sites, as only by comparing the genetic profiles of cultivated and wild specimens can the potential sites of domestication be identified. The main goal of the presented research was the next-generation sequencing (NGS) of complete plastid genomes mainly from European and Mediterranean wild grapevines, as well as cultivated varieties from Europe and Georgia (South Caucasus), and American and Asian Vitis species, followed by in silico genome assembly and phylogenetic analyses. The results revealed that plastomes of European and Mediterranean wild grapevines predominantly exhibit the so-called GTA haplotype; Portuguese wild grapevines exhibit a new type of ATA plastid haplotype; Plastomes of Asian and American species are distinct from those of European and Mediterranean grapevines and the Rkatsiteli haplotype (AAA) remains genetically unique among the plastomes sequenced to date.

Somatic embryogenesis and organogenesis: driving regeneration forces behind grapevine genetic transformation

Cell pluripotency, enables the possibility to change the cellular fate, stimulating the reorganization and the formation of new vegetative structures from differentiated somatic tissues. Although several factors are implicated in determining the success of a breeding program through the use of modern biotechnological techniques, the definition of a specific regeneration strategy is fundamental to speed up and make these applications feasible.

Novel ATR-FTIR and UV-Vis spectral markers for assessing the Prooxidant/Antioxidant Balance (PAB) in white wines

The browning index (BI), based on the absorbance at 420 nm, is a common oxidation marker in white wines, typically measured after thermal stress (50–60 °C for 5 up to 12 days) in air-saturated wines.

Genetic traceability of the varietal origin of wines: a robust application for must and wines during alcoholic fermentation

Industry and regulatory agencies have developed regulations to ensure authenticity and compliance with wine composition limits. However, this can be truncated by the absence of simple and robust analytical methodologies, uninfluenced by the environment, different oenological techniques and cultural practices. Genetic fingerprinting is the most powerful tool for unequivocal varietal identification; it is not affected by the environment or agronomic practices; however, its usefulness in musts and wines has been controversial and there is currently no routine certification of varietal origin based on DNA analysis.

The science of fungi in grapevine: An essential new book covering all aspects of fungi in viticulture

Grapevine is one of the world’s most important cultivated plants, domesticated from the wild vine over 11,000 years ago. The fungi associated with it are doubtless as old as the plant itself. Despite their co-evolution with the vine over the centuries, it was only with the invention of the microscope in the seventeenth century that fungi started to be recognised.

Wine consumption in Ukraine: trends, socio-economic aspects, and public perception

This article explores the contemporary culture of wine consumption in Ukraine through the lens of social, economic, and cultural transformations triggered by European integration, the COVID-19 pandemic, and the full-scale war since 2022.
