RNA-guided genome editing using the CRISPR/Cas9 CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 (CRISPR-associated protein 9) system has been applied successfully in several plant species. However, to date, there are few reports on the use of any of the current genome editing approaches in grape-an important fruit crop with a large market not only for table grapes but al...

The changes in some physicochemical properties, sugar, organic acid and volatile compound contents fresh Verdani grape (Vitis vinifera L.) juice (FGJ) were evaluated the production of its traditional molasses (pekmez). After production, total soluble solid (TSS), titratable acidity (TA), glucose, fructose, malic, citric succinic concentrations increased (P

Among the dramatic changes occurring during grape berry (Vitis vinifera) development, those affecting the flavonoid pathway have provoked a number of investigations in the last 10 years. In addition to producing several compounds involved in the protection of the berry and the dissemination of the seeds, final products of this pathway also play a critical role in berry and wine quality. In this...

61 Anthocyanins are flavonoid compounds responsible for red/purple colours in the leaves, fruit and flowers 62 of many plant species. They are produced through a multistep pathway which is controlled by MYB 63 transcription factors. VvMYBA1 and VvMYBA2 activate anthocyanin biosynthesis in grapevine (Vitis 64 vinifera) and are non-functional in white grapevine cultivars. In this study, transgeni...

222 cultivated (Vitis vinifera) and 22 wild (V. vinifera ssp. sylvestris) grape accessions were analysed for genetic diversity and differentiation at eight microsatellite loci. A total of 94 alleles were detected, with extensive polymorphism among the accessions. Multivariate relationships among accessions revealed 16 genetic groups structured into three clusters, supporting the classical eco-g...

The dynamics of Xylophilus ampelinus were studied in Vitis vinifera cv. Ugni blanc using gfp-marked bacterial strains to evaluate the relative importance of epiphytic and endophytic phases of plant colonization in disease development. Currently, bacterial necrosis of grapevine is of economic importance in vineyards in three regions in France: the Cognac, Armagnac, and Die areas. This disease is...

The ripening of grape (Vitis vinifera L.) is characterized by massive sugar import into the berries. The events triggering this process and the pathways of assimilate transport are still poorly known. A genomic clone Vvht1 (Vitis vinifera hexose transporter1) and the corresponding cDNA encoding a hexose transporter whose expression is induced during berry ripening have been isolated. Vvht1 is e...

Resveratrol is positively correlated with grapevine disease resistance and its consumption is also highly beneficial to human health. HPLC analyses showed that resveratrol content was significantly higher in most wild Chinese grapevines than in most European Vitis vinifera grapevine cvs. Fruit of the wild Chinese genotype Vitis quinquangularis Danfeng-2 contains much higher levels of resveratro...

The North Carolina wine industry is growing at a fast pace. Many new vineyards are being planted with European varieties. Vitis vinifera varieties in general are the most challenging species of grape grown, requiring considerable effort to consistently produce yields of appropriate volume and good quality. The model produced in this research was designed to help guide site selection for V. vini...

Grapevine (Vitis vinifera L.) is one of the most important fruit crop worldwide. Commercial cultivars are greatly affected by a large number of pathogenic microorganisms that cause diseases during pre- and/or post-harvest periods, affecting production, processing and export, along with fruit quality. Among the potential threats, we can find bacteria, fungi, oomycete, or viruses with different l...
