Significance The earliest biomolecular archaeological and archaeobotanical evidence for grape wine viniculture from the Near East, ca. 6,000–5,800 BC during early Neolithic Period, was obtained by applying state-of-the-art archaeological, archaeobotanical, climatic, chemical methods to newly excavated materials two sites in Georgia South Caucasus. Wine is central civilization as we know it West. As a medicine, social lubricant, mind-altering substance, highly valued commodity, became focus...
The mountainous region between the Caucasus and China is considered to be center of domestication for grapevine. Despite importance Central Asia in history grape growing, information about extent distribution genetic variation this limited comparison wild cultivated grapevines from around Mediterranean basin. principal goal work was survey diversity relationships among germplasm Caucasus, Asia, basin collectively understand gene flow, possible events adaptive introgression.A total 1378...
Abstract Background Grape ripening represents the third phase of double sigmoidal curve berry development and is characterized by deep changes in organoleptic characteristics. In this process, skin plays a central role synthesis many compounds interest ( e.g . anthocyanins aroma volatiles) fundamental protective barrier against damage physical injuries pathogen attacks. order to improve knowledge on tissue during ripening, protein expression red cultivar Barbera at five different stages from...
Background and Aims In the light of possible climate change, a crucial aspect for future Mediterranean Europe viticulture is selection new rootstocks exhibiting adaptability to drought salt stress. this context considering recent literature, it fundamental increase our knowledge biochemical physiological events that characterise stress responses in grapevine roots. study, leaf root induced by water (WS) sodium chloride (NaCl) exposure selected genotype, named M4 (Vitis vinifera × V....
Plasmopara viticola (Berk. et Curt.) Berl. and de Toni, the agent of downy mildew, is one most important pathogens European grapevine (Vitis vinifera L.). Extensive evaluation cultivated germplasm has highlighted existence resistant phenotypes in Georgian (Southern Caucasus) germplasm. Resistance shown as a reduction disease severity. Unraveling genetic architecture response to P. infection crucial develop varieties reduce impact management. The aim this work was apply genome-wide...
Georgia, in the Caucasian region, is considered first domestication centre of grapevine. This country characterized by high morphological variability cultivated (Vitis vinifera L. subsp. sativa (DC.) Hegi) and wild sylvestris (Gmel.) compartments. The main objective this study was to investigate level genetic diversity obtained novel custom Vitis18kSNP array, order analyse 71 grapevine accessions representative Georgian germplasms. number loci successfully amplified 15,317 out 18,775 SNP 79...
Roots play a central role in plant response to water stress (WS). They are involved its perception and signalling the leaf as well allowing adapt maintaining an adequate balance. Only few studies have investigated molecular/biochemical responses WS roots of perennial plants, such grapevine. This study compares two grapevine rootstock genotypes (i.e. 101.14 M4) with different tolerance WS, evaluating at proteomic metabolite levels.WS induced changes abundance several proteins both (17 22%...
The Eurasian grapevine (Vitis vinifera), an Old World species now cultivated worldwide for high-quality wine production, is extremely susceptible to the agent of downy mildew, Plasmopara viticola. cultivation resistant V. vinifera varieties would be a sustainable way reduce damage caused by pathogen and impact disease management, which involves economic, health environmental costs frequent fungicide application. We report finding unique mildew resistance traits in winemaking cultivar from...
In Georgia, one of the most ancient vine-growing environment, homemade production wine is still very popular in every rural family and spontaneous fermentation must, without addition chemical preservatives, norm. The present work investigated yeast biodiversity five Georgian areas (Guria, Imereti, Kakheti, Kartli, Ratcha-Lechkhumi) sampling grapes wines from 22 different native cultivars, 26 vineyards 19 cellars. One hundred eighty-two isolates were ascribed to 15 species by PCR-ITS RFLP,...
Downy mildew, caused by the oomycete Plasmopara viticola, is one of diseases causing most severe economic losses to grapevine (Vitis vinifera) production. To date, application fungicides efficient method control pathogen and implementation novel sustainable disease methods a major challenge. RNA interference (RNAi) represents biotechnological tool with great potential for controlling fungal pathogens. Recently, candidate susceptibility gene (VviLBDIf7) downy mildew has been identified in V....
Among the main challenges in current viticulture, there is increasing demand for sustainability protection from fungal diseases, such as downy mildew (DM) and powdery (PM). Breeding disease-resistant grapevine varieties a key strategy better managing fungicide inputs. This study explores diversity of germplasm (cultivated wild) Caucasus neighboring areas to identify genotypes resistant DM PM, based on 13 Simple Sequence Repeat (SSR) loci phenotypical (artificial pathogen inoculation)...
A three year survey on the dominant yeast populations in samples of air, must and wine different vineyards cellars two northern Italian vine-growing territories (six sites Franciacorta eight Oltrepò Pavese areas) was carried out. total 505 isolates were ascribed to 31 species by RFLP analysis ITS1–5.8SrRNA–ITS2 region partial sequence 26S rRNA gene. The most commonly found Saccharomyces cerevisiae (frequency, F′ = 58.7 %; incidence, I' 53.5 %), Hanseniaspora uvarum (F′ 14.3 I′ 5.3...
Cultivars used for wine and table grape have self-fertile hermaphrodite flowers whereas wild European vines American Asian species are dioecious, having either male or female flowers. Consistent with previous studies, the flower sex trait was mapped as a single major locus on chromosome 2 based pure Vitis vinifera population segregating progeny, hybrid producing all three types. The placed between same SSR SNP markers both genetic maps, although abnormal segregation hampered to fine map...
Sunburn can affect grape quality both for chemical modifications and by visual impact of the browning. Optical properties 17 white accessions were investigated in visible region using a noninvasive instrument. Reflectance spectra obtained Jaz System spectrometer. Browning was induced exposing bunches to direct sunlight at 12:30 p.m. 5 h. During experiment, global solar radiation ranged from 2.6 2.7 MJ m-2 h-1 air temperature 24.3 29.2 °C; exposed berries reached 34.2 °C comparison 30.4...
