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.

Alcohol preference and health behaviors in patients with cardiometabolic diseases: insights from the multi-center iact cross-sectional study

Recognizing the influence of alcohol preference on health behaviors is essential for developing tailored interventions that effectively promote healthier lifestyles and optimize disease management strategies in the vulnerable population of patients with cardiometabolic diseases (CMD). The present study aims to provide valuable insights into how alcohol preference relates to dietary habits and medication adherence among patients with CMD diseases.

Isotopes to distinguish production system in Brazilian viticulture

Organic viticulture integrates practices aimed at foresting positive relationships among, vines, soil, and climate, with a focus on sustainability, social responsibility, and environmental protection. To safeguard production integrity, regulatory bodies worldwide conduct organic certifications in accordance with relevant regulations. Considering that agriculture practices influence the nitrogen, carbon and oxygen isotope composition, the study aimed to investigate the response of these isotopes in grape must cultivated by organic, biodynamic and conventional methods to distinguish between production systems.

Towards an ecological architecture inspired by underground cellars: An example of the thermal inertia of Moldovan underground cellars and new geothermal and Canadian well approaches

The search for underground shelters is one of the oldest forms of human habitation, providing refuge in extreme environments such as deserts and polar regions.

New ways of grape pomaces valorization: production of functional beverages or nutraceuticals

The wine industry generates each year 20 million tons of by-products. Among them grape pomaces represent a big part that can be considered as a source of potentially bioactive molecules such as polyphenols. Kombucha fermentation is an ancestral process which allow to increase the biological properties of tea by the action of a microbial consortium formed by yeasts and bacteria called scoby.

Acumulación de materia seca, orientada a valorar la fijación de carbono, en función del aporte de riego y la pluviometría, en Cabernet-Sauvignon a lo largo de 15 años

The vineyard is capable of fixing carbon in its permanent structure from atmospheric carbon dioxide, through the process of gas exchange and the performance of photosynthesis. The photosynthetic capacity of the vineyard depends on the water resources that the plant may have at its disposal, so the amount of dry matter, derived from the processed photosynthates, that it can store will depend on the water regime of the crop, both in the annually renewable organs as in permanent parts.
