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

Abstract

Italy is a rich hub of viticultural biodiversity harboring hundreds of indigenous grape varieties that have adapted over centuries to the diverse climatic and geographic conditions of its regions. Preserving this biodiversity is essential for maintaining a diversified genetic pool, crucial for addressing future challenges such as climate change and emerging plant diseases. Rising temperatures, precipitation pattern variations, and extreme weather events can affect grape ripening, crop quality, and contribute to disease development. Integrated disease management necessitates exploration of novel strategies. Biotechnologies emerge as a significant player in tackling modern viticulture challenges. New plant breeding technologies (NpBT) can be employed in grapevine cultivation and, in particular, genome editing through CRISPR/Cas9 system has been shown to be a valid application for targeted mutagenesis, by until now its application is restricted on a few cultivars. Genetic improvement via in vitro delivery of desired constructs requires the regeneration of genome-edited plants. In vitro plant regeneration, a pivotal process in genetic engineering, encounters obstacles, particularly in grapevines, due to factors like genotype and explant-dependent responses. Therefore, reliable in vitro regeneration and propagation systems are imperative. Understanding and enhancing regeneration across different genotypes are critical steps in advancing genetic improvements and gene functional studies in grapevines. The study focuses on developing an efficient in vitro plant regeneration protocol by somatic embryogenesis (SE) of the grapevine cv. Aglianico, the most important grapevine variety of southern Italy regions. The embryogenic materials obtained will be used for future functional studies through genome editing approaches.

Recent advances in measuring, estimating, and forecasting grapevine yield and quality

Grapevine yield and fruit quality are two major drivers of input allocation and, ultimately, revenue for grape producers. Because yield and fruit quality vary substantially from year-to-year and within a single block, opportunities exist for optimization via precision management activities that could lead to more profitable and sustainable grape production. Here, we review recent advances in the techniques and technology used to measure, estimate, and forecast grapevine yield and fruit quality. First, we discuss direct “measurement” of yield and quality (i.e. ground-truth data generation), with an emphasis on potential for scalability and automation. Second, we discuss technology and techniques that do not directly measure yield and quality, but use correlated measurements for their estimation.

Techniques for sunburn reduction in bunches in Vitis vinifera L. cv. Graciano

Sunburn results from a combination of excessive photosynthetically active radiation (PAR) and UV radiation and temperature that can be exacerbated by other stress factors such as water deficit. Sunburn is a physiological disorder that affects the visual and organoleptic properties of grapes. The appearance of brown and necrotic spots severely affects the commercial value of the fruit, and in extreme cases, significantly decreases yield. This damage occurs with some frequency in sensitive varieties such as Graciano.

The evolution of the concept of geographical denomination in South America

Vers la fin du XX siècle, la vitiviniculture argentine a subi une profonde transformation qualitative atteignant toute la filière. L’analyse de l’évolution de la superficie des vignobles, l’élaboration des vins, la consommation et les exportations, permet de mettre en évidence ces changements. Dans ce contexte, l’origine apparaît comme un outil de force, d’expansion et de succès sur les marchés.
