Abstract:

Vitis rotundifolia (Muscadine grapes), a native species characterized with multiple resistance to grape diseases and insects, are cultivated throughout the southeastern U.S. for fresh fruit and processing. However, the species falls short of consumer's expectation as fresh fruit due to its seediness and thick skin. However, Vitis vinifera, a predominant Vitis species grown worldwide possesses good fruit characteristics such as seedlessness and edible skin but is susceptible to many diseases. Attempts to produce rotundifolia-vinifera hybrids to combine good fruit quality and disease resistance of both into F1 hybrids have been made by grape breeders for many years. Limited success was only reported when the V. vinifera was used as seed parents. Pollinating seedless vinifera pollen onV. rotundifolia stigma was made in 1993 and 1994. More than 20,000 flowers from 34 cross combinations were pollinated. These crosses were made to see if there is any chance to produce hybrids when muscadine grapes were used as female parent and specifically to introgress the seedlessness from European grapes into muscadine grapes. A few hundred seeds were collected from these crosses and germinated in a greenhouse. Two seedlings were clearly distinguished from the others with morphology intermediate between muscadine and the vinifera grapes, while the rest looked straight muscadine grapes derived from possible contaminated pollination. This conclusion was further confirmed by isozyme and DNA markers. One of the seedlings produced from the cross of `Jumbo' × `Thompson Seedless' grew vigorously and has been setting fruit since 1996. Fruit are mixture of stenospermocarpic and pathonocarpic seedlessness. Fruit setting and pollen viability test indicated that this hybrid is at least partly self-fertile. Many other characteristics of the hybrid, such as leaves, stems, tendrils, time of budbreak, bloom date, and ripen date are intermediate between muscadine and bunch grapes. The hybrid is resistant to Pierce's disease, anthracnose disease, and downy mildew, which are the limited factor to growing V. vinifera in the hot and humid southeastern U.S. This is the first report of a seedless hybrid from V. rotundifolia × V. vinifera.

Abstract:

Wine has been produced in Georgia since the 6th millennium BC. The processes of cultivar selection and breeding started with wild grapes Vitis vinifera L. ssp. sylvestris Gmel. and included multiple introgression events—from the wild to domestication. This article aims at improving the knowledge concerning the history of winemaking through a comparison of the Vitis vinifera subsp. sylvestris and subsp. sativa. Grapes of Vitis vinifera subsp. sylvestris were grown in an ampelographic collection and vintages 2017–2020 were analyzed. The obtained data were compared to a wider dataset available in literature concerning Vitis vinifera subsp. sativa, demonstrating the central role of grape morphology in the domestication process. This evidence suggests that the technological value of the cultivars played an important role in the selection process. In vintages 2017, 2018, and 2019, wines were produced with Vitis vinifera subsp. sylvestris grapes and compared with Cabernet Sauvignon and Saperavi vinifications. For all the vintages, the fermentations took shorter time for wild grape, despite the highest content of total phenols. Learning from the past, Vitis vinifera subsp. sylvestris might still be an interesting genetic resource for future breeding programs. Furthermore, the possible combination of wild and domesticated grapes can make possible the production of wines with long ageing, exalting their own characteristics.

Abstract:

Vitis and non-Vitis spp. surrounding nine Napa Valley vineyards were surveyed for Grapevine leafroll-associated virus (GLRaV)-1 to -5 and -9, Grapevine virus A (GVA), Grapevine virus B (GVB), and Grapevine virus D (GVD). Vitis spp. from three riparian areas not adjacent to vineyards were also included. DNA fingerprinting and probability analyses indicated that the Vitis samples consisted primarily of Vitis californica followed by V. californica × V. vinifera hybrids. Single and mixed infections of GLRaV-2, -3, GVA, or GVB were detected by conventional or quantitative reverse-transcription polymerase chain reaction in 6 of the 66 V. californica and 11 of the 19 V. californica × V. vinifera hybrids. GLRaV-1, -4, -5, -9, and GVD were not detected. Phylogenetic analysis of GLRaV-2 and -3 partial coat protein gene nucleotide sequences indicated that the isolates from V. californica and V. californica × V. vinifera hybrids were closely related to isolates from V. vinifera.

Abstract:

The recovery of inaperturate pollen from functionally female flowers in archaeological layers opens the question of a possible pollen-based discrimination between wild and domesticated Vitis vinifera in prehistoric times. Pollen analysis applied to archaeology has not routinely considered the existence of pollen dimorphism in Vitis, a well-known trait in the field of agrarian studies. Therefore, the inaperturate shape of grapevine pollen is ignored by studies on the archaeobotanical history of viticulture. In this paper we investigate pollen morphology of the domesticated and wild subspecies of V. vinifera, and report the first evidence of inaperturate Vitis pollen from an archaeological site. We studied exemplar cases of plants with hermaphroditic flowers, belonging to the subspecies vinifera with fully developed male and female organs, cases of dioecious plants with male or female flowers, belonging to the wild subspecies sylvestris and cases of V. vinifera subsp. vinifera with morphologically hermaphroditic but functionally female flowers. The pollen produced by hermaphroditic and male flowers is usually trizonocolporate; the pollen produced by female flowers is inaperturate. This paper reports on the inaperturate pollen of Vitis found in an archeological site of the Po Plain, Northern Italy. The site dated to the Bronze Age, which is known to have been a critical age for the use of this plant with a transition from wild to domesticated Vitis in central Mediterranean. Can the inaperturate Vitis pollen be a marker of wild Vitis vinifera in prehistoric times? Palynology suggests a possible new investigation strategy on the ancient history of the wild and cultivated grapevine. The pollen dimorphism also implies a different production and dispersal of pollen of the wild and the domesticated subspecies. Grapevine plants are palynologically different from the other Mediterranean “cultural trees”. In fact, Olea, Juglans and Castanea, which are included in the OJC index, have the same pollen morphology and the same pollen dispersal, in wild and domesticated plants. In contrast, the signal of Vitis pollen in past records may be different depending on the hermaphroditic or dioecious subspecies.

Abstract:

The narrow genetic base of modern cultivars is becoming a key bottleneck for crop improvement and the use of wild relatives is an appropriate approach to improve the genetic diversity of crops to manage the sustainable production under different abiotic and biotic constraints. In Pakistan, wild germplasm of grapevine viz Dakh, Toran, and Zarishk belong to Vitis vinifera subsp. sylvestris and Fatati belong to Vitis vinifera subsp. sativa is naturally present in humid and sub-humid areas of mountainous and sub-mountainous regions and showed varying level of tolerance against drought stress but have not been evaluated as rootstock. In this study, different tolerant behavior of wild grapevines as rootstock in grafted scion varieties were explored under different levels of PEG-6000 mediated drought stress i.e., -4.00, -6.00, and -8.00 bars. In response to drought stress, wild grapevines evoked several non-enzymatic and enzymatic activities. Among non-enzymatic activities, total chlorophyll contents of commercial varieties were sustained at higher level when grafted on wild grapevines Dakh and Fatati which subsequently reduced the damage of cell membrane via MDA. Whereas, to cope the membranous damage due to excessive cellular generation of ROS, wild grapevines triggered the enhanced activities of SOD to dismutase the free oxygen radicals into H2O2, then CAT enzyme convert the H2O2 into water molecules. Higher accumulation of ROS in commercial scion varieties were also coped by wild grapevines Dakh and Fatati through the upregulation of POD and APX enzymes activities. Based on these enzymatic and non-enzymatic indices, biplot and cluster analysis classified the wild grapevines as rootstock into three distinct categories comprises on relatively tolerant i.e., Dakh (Vitis vinifera subsp. sylvestris) and Fatati (Vitis vinifera subsp. sativa), moderate tolerant i.e., Toran (Vitis vinifera subsp. sylvestris) and relatively susceptible category i.e., Zarishk (Vitis vinifera subsp. sylvestris).

Abstract:

Muscadine grape (Vitis rotundifolia) is highly resistant to many diseases and insects that attack european grape (Vitis vinifera). However, distant hybridization incompatibility between V. rotundifolia (female) and V. vinifera (male) impedes the utilization of V. rotundifolia in grape breeding. This study used fourth-dimension label-free protein quantitation to detect the key genes and pathways in the V. rotundifolia stigma after self-pollination (V. rotundifolia × V. rotundifolia) and cross-pollination (V. rotundifolia × V. vinifera). A histological analysis showed that pollen tube growth in the stigma of V. rotundifolia was arrested 8 hours after cross-pollination, but not after self-pollination. A proteomic analysis identified 32 differentially expressed proteins (DEPs) in the stigma of V. rotundifolia between self-pollination and cross-pollination. A heatmap analysis grouped these DEPs into four clusters. The top gene ontology terms were ATPase-coupled transmembrane transporter activity, extracellular region, DNA replication, and cellular carbohydrate biosynthetic process. A Kyoto Encyclopedia of Genes and Genomes analysis revealed that these DEPs participated in DNA replication and starch and sucrose metabolism pathways. The downregulated A5AY88, D7TJ35, D7SU26, F6HJI1, and F6GUE7 may have a role in cross incompatibility. This study revealed the cross incompatibility of grapes at histological and proteomic levels.

Abstract:

Morphometric methods based on artificial vision algorithms provide measurements for magnitudes descriptive of seed images (i.e., the length, width, area, and surface circularity index). Nevertheless, their results frequently omit the resemblance of the images to geometric figures that may be used as models. A complementary method based on the comparison of seed images with geometric models is applied to seeds of Vitis spp. The J index gives the percentage of similarity between a seed image and the model. Seven new geometric models are described based on the heart-shaped and piriform curves. Seeds of different species, subspecies and cultivars of Vitis adjust to different models. Models 1 and 3, the heart curve and the water drop, adjust better to seeds of V. amurensis, V. labrusca and V. rupestris than to V. vinifera. Model 6, the Fibonacci’s pear, adjusts well to seeds of V. vinifera, in general, and better to V. vinifera ssp. vinifera than to V. vinifera ssp. sylvestris. Seed morphology in species of Cissus and Parthenocissus, two relatives of Vitis in the Vitaceae, is also analysed. Geometric models are a tool for the description and identification of species and lower taxonomic levels complementing the results of morphometric analysis.

Abstract:

The use of consensus chloroplast microsatellites primers for dicotyledonous chloroplast genomes revealed the existence of intra and interspecific length variation within the genus Vitis. Three chloroplast microsatellite loci were found to be polymorphic in samples of Vitis vinifera, Vitis berlandieri, Vitis riparia, and Vitis rupestris out of a total of 10 consensus primer pairs tested. These polymorphisms were always due to a variable number of mononucleotide residues within A and (or) T stretches in the amplified regions. Chloroplast microsatellite polymorphisms were used to demonstrate the maternal inheritance of chloroplast in V. vinifera and to characterise the chloroplast haplotypes present in wine grape cultivars of this species grown in Spain and Greece. The different distribution of haplotype frequencies in the two ends of the Mediterranean growth area suggests the existence of independent domestication events for grapevine.Key words: Vitis, grapevine, chloroplast microsatellites, chloroplast haplotypes, chloroplast inheritance, grapevine domestication.

Abstract:

Botrytis cinerea, the causal agent of Botrytis bunch rot and gray mold, is the number one postharvest disease of fresh grapes in the United States. Fungicide applications are used to manage the disease, but fungicide-resistant isolates are common and postharvest losses occur annually. Host resistance is needed for long-term management of the disease. Sources of resistance in grape have been identified, but often have poor fruit quality. In this study, 27 grape lines (cultigens and species), including high fruit–quality Vitis vinifera, were evaluated for fruit and leaf susceptibility to two isolates of B. cinerea. No significant differences in virulence or pathogenicity were detected between the two isolates, but differences in disease incidence were evident among lines in leaves and berries. Most V. vinifera cultivars evaluated had high disease incidence in berries, whereas complex hybrids, Vitis aestivalus and Vitis arizonica, had low- to moderate disease incidence. Two V. vinifera breeding lines had moderate susceptibility (<50% disease) to Botrytis bunch rot when inoculated with either isolate. Only one V. vinifera line had little (<5%) to no berry or leaf disease when inoculated with either isolate. Moderate resistance (10% to 25%) was detected in Vitis spp., and a single V. vinifera line. Correlations were examined among soluble solids, leaf susceptibility, and fruit susceptibility. No correlations between soluble solids and disease susceptibility (leaves or berries) were identified, but moderate correlations between leaf and berry susceptibility were observed. Moderate resistance to Botrytis bunch rot and leaf spot were detected in Vitis breeding lines, suggesting these may be useful for developing grape cultivars with high fruit quality and resistance to B. cinerea.

Abstract:

UV radiation causes various skin problems starting from reddening of skin to the change in the shape of DNA which further leads to the skin cancer. Considering harmful effect of UV radiation present study was designed to develop an environmental friendly UV protective finish for cotton fabric using Vitis vinifera leaves. Process parameters of the study were optimized using response surface methodology for getting maximum UV protection while maintaining other physical properties of the fabric. It was found that 9.038 % concentration of extract with 60 minutes of exhaustion time at 40.909oC exhaustion temperature were selected as optimum conditions for application of Vitis vinifera extract on cotton fabric. It can be concluded that application of Vitis vinifera extract on cotton fabric incorporates UV protection properties on cotton fabric which can be helpful to prevent various UV induced skin problems.

Abstract:

Transgenic grapevines were regenerated from somatic embryos produced from immature zygotic embryos of two seedless grape selections and from leaves of in vitro-grown plants of `Thompson Seedless'. Somatic embryos were bombarded with gold microparticles using the Biolistic PDS-1000/He device (Bio-Rad Labs) and then exposed to engineered A. tumefaciens EHA101 (E. Hood, WSU). Alternately, somatic embryos were exposed to A. tumefaciens without bombardment. Following cocultivation, secondary embryos multiplied on Emershad and Ramming proliferation medium under kan selection. Transgenic embryos were identified after 3 to 5 months and developed into rooted plants on woody plant medium with 1 mM N6-benzyladenine, 1.5% sucrose, and 0.3% activated charcoal. Seedless selections were transformed with plasmids pGA482GG (J. Slightom, Upjohn) and pCGN7314 (Calgene), which carry GUS and NPTII genes. `Thompson Seedless' was transformed with pGA482GG and pGA482GG/TomRSVcp-15 (D. Gonsalves, Cornell Univ.) containing the tomato ringspot virus coat protein gene. Integration of foreign genes into grapevines was verified by growth on kan, GUS, and PCR assays, and Southern analyses.

Abstract:

Vitis vinifera can be divided into two subspecies, V. vinifera subsp. vinifera, one of the most important agricultural crops in the world, and its wild ancestor, V. vinifera subsp. sylvestris. Three flower types can be observed: hermaphrodite and female (on some varieties) in vinifera, and male or female flowers in sylvestris. It is assumed that the different flower types in the wild ancestor arose through specific floral patterns of organ abortion. A considerable amount of data about the diversity of sexual systems in grapevines has been collected over the past century. Several grapevine breeding studies led to the hypothesis that dioecy in vinifera is derived from a hermaphrodite ancestor and could be controlled by either, one or two linked genetic determinants following Mendelian inherence. More recently, experiments using molecular approaches suggested that these loci were located in a specific region of the chromosome 2 of vinifera. Based on the works published so far, its seems evident that a putative sex locus is present in chromosome 2. However, it is still not fully elucidated whether flower types are regulated by two linked loci or by one locus with three alleles. Nevertheless, several genes could contribute to sex determination in grapevine. This review presents the results from early studies, combined with the recent molecular approaches, which may contribute to the design of new experiments towards a better understanding of the sex inheritance in grapevine.

Abstract:

Eastern North America is considered the center of diversity for many Vitis spp. and for the grape powdery mildew pathogen, Erysiphe necator. However, little is known about populations of E. necator from wild Vitis spp. We determined the phenotypic variation in pathogenicity and aggressiveness of E. necator among isolates from wild and domesticated Vitis spp. from diverse geographic regions in the eastern United States. To test pathogenicity, we inoculated 38 E. necator isolates on three wild Vitis spp., two commercially grown hybrids and the European wine grape, Vitis vinifera. V. rotundifolia (muscadine grape) was the only host species on which complete host specialization was evident; it was only susceptible to isolates collected from V. rotundifolia. All isolates, regardless of source host, were pathogenic on the other Vitis spp. We found no differences in components of aggressiveness latent period and lesion size among isolates from different source hosts when inoculated on V. vinifera, which is highly susceptible to powdery mildew. However significant variation was evident among isolates on the more resistant V. labruscana ‘Niagara’. Isolates from the wild species V. aestivalis were the most aggressive, whereas isolates from V. vinifera were not more aggressive than isolates from other source hosts. Greater aggressiveness was also detected among isolates from the southeastern United States compared with isolates from the northeastern United States.

Abstract:

Single nucleotide polymorphism (SNP) genotyping arrays are powerful tools to measure the level of genetic polymorphism within a population. The coming of next-generation sequencing technologies led to identifying thousands and millions of SNP loci useful in assessing the genetic diversity. The Vitis genotyping array, containing 18k SNP loci, has been developed and used to detect genetic diversity of Vitis vinifera germplasm. So far, this array was not validated on non-vinifera genotypes used as grapevine rootstocks. In this work, a core collection of 70 grapevine rootstocks, composed of individuals belonging to Vitis species not commonly used in the breeding programs, was genotyped using the 18k SNP genotyping array. SNP results were compared to the established SSR (Simple Sequence Repeat) markers in terms of heterozygosity and genetic structure of the core collection. Genotyping array has proved to be a valuable tool for genotyping of grapevine rootstocks, with more than 90% of SNPs successfully amplified. Structure analysis detected a high degree of admixed genotypes, supported by the complex genetic background of non-vinifera germplasm. Moreover, SNPs clearly differentiated non-vinifera and vinifera germplasm. These results represent a first step in studying the genetic diversity of non-conventional breeding material that will be used to select rootstocks with high tolerance to limiting environmental conditions.

Abstract:

We report the organization of a grapevine chimeric gene Adhr-Vine-1, composed by an Adhr gene, into which a retroelement, Vine-1, was inserted. Sequence analysis revealed that Adhr is a member of the Adh multigene family, but does not correspond to any other grapevineAdh described to date. Vine-1, albeit defective, is the most complete LTR (long terminal repeat)-retrotransposon-like element described in Vitis vinifera L. It is 2392 bp long, with two almost identical LTRs (287 bp) in the same orientation, and flanked by direct repeats of a 5 bp host DNA. This element presents other features, characteristic of retroviruses and retrotransposons including inverted repeats, a primer binding site, and a polypurine tract. It has a single open reading frame (ORF) of 581 amino acids, potentially encoding for a gag protein and parts of the protease and integrase proteins. Vine-1 is most likely related to the copia-like type family, but with no significant similarity to any previously described plant retrotransposon or inserted element, nor to any eukaryotic element described to date. Vine-1 element has been found in Adhr at the same location in different V. vinifera cultivars, but not in some other analyzed Vitis species. These data suggest that Vine-1 insertion in Adhr is specific to V. vinifera, and has occurred after the Adh isogene separation, but prior to cultivar development. Sequences related to Vine-1 were revealed in multiple copies in the V. vinifera genome and, to a lesser extent, in other analyzed Vitis species. The polymorphism observed prompts us to question the role played by transposition in the evolution of the Vitis genus. Key words: alcohol dehydrogenase, LTR, polymorphism, retrotransposon, Vitis vinifera L.

Abstract:

Endophytes are microorganisms that live asymptomatically inside plant tissues. They are beneficial to their host in many aspects, especially as a defense against foreign phytopathogens through the production of a variety of metabolites. These substances can serve as sources of new natural products for medicinal, agricultural, and industrial purposes. This article is focused on endophytic fungi from Vitis vinifera. The purpose of the research was their isolation and identification during the Vitis vinifera growing season. Subsequently, the isolates were tested for the production of biotechnologically interesting metabolites (siderophores, antioxidants, and antifungal compounds). In total, 24 endophytic fungi were isolated, the most represented genus was Cladosporium sp. The results of the test for antioxidant and antifungal properties, as well as siderophore production, have shown that the population of Vitis vinifera endophytic microscopic fungi could serve as a promising source of metabolites with a wide range of applications.

Abstract:

AbstractThis paper reviews the, so far available, paleorecords of Vitis sylvestris C.C. Gmel and Vitis vinifera L. from Romania. The study takes into consideration the presence of Vitis pollen from Holocene peat sediment sequences and archaeological context, but also the presence of macrorests from various archaeological sites that date from Neolithic, Chalcolithic, Bronze Age, and La Tène. Both paleobotanical arguments and archaeological discoveries support the theory that places the beggining of viticulture in Romania a few millenia ago, in Neolithic period. Also, written evidences (works of classical authors, epigraphical sources) confirm, indirectly, the presence of grapevine in La Tène period. Occurrences of Vitis vinifera and those of Vitis sylvestris manifest independently of the climate oscillations, being present both through colder and more humid episodes, as well as through drier and warmer events. Probably prehistoric communities have made a constant and deliberate effort, all along the Holocene, to maintain grapevine crops.

Abstract:

Cultivars of European grapevine, Vitis vinifera, show varying levels of susceptibility to Eutypa dieback and Esca, in terms of foliar symptoms. However, little is known regarding cultivar susceptibility of their woody tissues to canker formation. Accordingly, we evaluated the relative susceptibility of V. vinifera cultivars (‘Cabernet Franc’, ‘Cabernet Sauvignon’, ‘Chardonnay’, ‘Merlot’, ‘Riesling’, ‘Petite Syrah’, and ‘Thompson Seedless’) and species or interspecific hybrids of North American Vitis (Vitis hybrid ‘Concord’, V. arizonica ‘b42-26’, V. rupestris × V. cinerea ‘Ill547-1’, and Fennell 6 [V. aestivalis] × Malaga [V. vinifera] ‘DVIT0166’) to canker formation by seven trunk pathogens (Neofusicoccum parvum, Lasiodiplodia theobromae, Phaeomoniella chlamydospora, Togninia minima, Phomopsis viticola, Eutypa lata, and an undescribed Eutypa sp.). Susceptibility was based on the length of wood discoloration (LWD) in the woody stems of rooted plants in duplicate greenhouse experiments. Cultivars of V. vinifera and Concord did not vary significantly in susceptibility to N. parvum or L. theobromae (LWD of 21 to 88 mm at 14 weeks post inoculation; P > 0.16), suggesting that they are similarly susceptible to Botryosphaeria dieback. The table-grape Thompson Seedless was most susceptible to P. viticola (mean LWD of 61 mm at 11 months post inoculation; P < 0.0001). V. vinifera cultivars and Concord showed similar susceptibility to the Esca pathogens, Phaeomoniella chlamydospora and T. minima. Susceptibility to E. lata was greatest in V. arizonica b42-26 (mean LWD of 96 mm at 11 months post inoculation; P < 0.03). In fact, all four American Vitis spp. were more susceptible to Eutypa dieback than the V. vinifera cultivars. Our findings suggest that no one cultivar is likely to provide resistance to the range of trunk pathogens but that certain cultivars may be promising candidates for commercially relevant host resistance in grape-production systems where the dominant cultivars are very susceptible.

Abstract:

Fungus-resistant grapes (FRGs), or pilzwiderstandfähig (PIWI) in German, are obtained through crossbreeding Vitis vinifera and other Vitis species. FRG adoption is among the most promising strategies to pursue and improve sustainability in the wine industry; however, actual spread and impact on sustainability will largely depend on designation and certification possibilities and procedures for FRG wines, in line with the framework set by the European Union (EU) Regulation 2021/2117. The aim of this study is to discuss the potential impact on consumers’ preferences of four hypothetical designation and certification settings for FRG wines: (I) new names without certification; (II) extended use of the original Vitis vinifera variety names without certification; (III) new names and ad-hoc designations (Protected Designation of Origin, PDO); (IV) extended use of the original Vitis vinifera variety names and existing PDOs. Participants’ reactivity to the alternatives was tested through market simulations on a non-probabilistic sample of 301 Italian university students. According to the results, extension of existing names and PDOs is the best option to enhance industry sustainability, preserve its quality paradigm, and fairly manage competition between traditional and new wines. Still, further investments are needed to promote FRG adoption and development.

Abstract:

Abscisic acid (ABA) metabolism is complex involving biosynthesis, conjugation, and catabolism. Differences in ABA metabolism (ABA, ABA-related metabolites, and transcripts) in response to water deficit (WD) were detected in leaves and roots of four Vitis species differing in drought tolerance: Vitis vinifera (Cabernet Sauvignon), Vitis champinii (Ramsey), Vitis riparia (Riparia Gloire), and Vitis vinifera x girdiana (SC2). Concentrations of ABA and ABA-related metabolites increased after moderate or severe WD depending on species, organ, and time. Differences in ABA, glycosylated-ABA, and ABA catabolite concentrations, as well as previously investigated related transcript abundances, revealed differences in ABA metabolism pathways among the species and organs. NCED3 was a key gene in the WD response of leaves and roots of all species. NCED3 transcript abundance and ABA concentration in drought-tolerant Ramsey increased earlier and to a greater extent than other species. These species provide informative genetic resources to study ABA metabolism and drought tolerance further.

Abstract:

Agricultural bioinoculants containing arbuscular mycorrhizal fungi represent a potential opportunity to reduce the dependence of grapevines (Vitis) on agrochemicals. This field study assessed the ability of four commercial bioinoculants to colonize grapevine roots and their effects on petiole nutrient concentration, berry composition, and root morphology of ‘Pinot noir’ (Vitis vinifera) grafted onto rootstock ‘Couderc 3309’ (Vitis riparia × Vitis rupestris) and ‘Riesling’ (V. vinifera) grafted onto ‘Couderc 3309’ and Selection Oppenheim four (Vitis berlandieri × V. riparia). Three bioinoculants increased root mycorrhizal colonization; however, regardless of the treatment, mycorrhizal fungal structures were enhanced. Grapevine petiole nutrient concentration was improved by bioinoculants. Root diameter, root length density, and specific root length increased with greater mycorrhizal root colonization. Using bioinoculants to reduce chemical fertilizers may be a good strategy to improve grapevine productivity and health in cool climates; however, the impact of mycorrhizal bioinoculants in the vineyard may differ among scion–rootstocks, edaphoclimatic conditions, and vineyard soil microbiomes.

Abstract:

A Vitis riparia genomic library was screened for the presence of (GA)n simple sequence repeats (SSR) and 18 primer pairs yielding amplification products of the expected size were designed. Heterologous amplification with the primer pairs in related species (V. rupestris, V. berlandieri, V. labrusca, V. cinerea, V. aestivalis, V. vinifera, and interspecific hybrids) was successful in most primer-species combinations. Therefore, the new markers are applicable to the genotyping of a range of Vitis species. Variations in the SSR flanking sequence were detected between and within the species. The degree of polymorphism and performance of the markers were determined in up to 120 individuals of V. vinifera. Four of fifteen alleles per locus were detected and expected heterozygosity ranged between 0.37 and 0.88. Null alleles were shown to be present at two loci by a lack of heterozygous individuals and by transmission of the null alleles in a controlled cross. Regular Mendelian inheritance is indicated for all but one loci by a preliminary segregation analysis in 36 offspring. Thirteen of the markers were found suitable for the genotyping of grapevines (V. vinifera).Key words: microsatellites, simple sequence repeats, Vitis.

Abstract:

The main objective was to study the effect of sample preparation on the content of trans-resveratrol, trans-ε-viniferin and trans-δ-viniferin in young spring grapevine canes. The samples of six varieties of Vitis vinifera L. (‘Hibernal’, ‘Malverina’, ‘Kolor’, ‘Fioletovij Augustovskij’, ‘Grüner Veltliner’ and ‘Blaufränkisch’) were either lyophilised or slow dried at room temperature (three months), extracted and analysed by HPLC using DAD and FLD detectors and by LC-MS. The presence of trans-δ-viniferin was confirmed by comparison with trans-δ-viniferin prepared by dimerization of trans-resveratrol using laccase and its structure was verified by LC-NMR. The slow drying of the samples at room temperature enables the synthesis of a significant amount of stilbenes in all the studied varieties of V. vinifera canes resulting in a higher stilbene content compared to the lyophilised samples. The results of this study show the importance of the method of drying the cane sample before the extraction and analysis.

In the current experiment, the in vitro anticoccidial effect of Vitis venifera (grape seed) extract was evaluated. For this purpose, an in vitro sporulation inhbition assay was used. Collected oocysts of four Eimeria species (E. tenella, E. necatrix, E. brunetti and E. mitis) were exposed to six different concentrations (w/v) of Vitis vinifera extract (VVE) in 10% Dimethylsulphoxide solution (DMSO), while Dimethylsulphoxide (DMSO) and Potassium dichromate solution (K2Cr2O7) served as control groups. The results of the present study revealed that V. vinifera extract showed inhibitory effect on sporulation (%) and damage (%) of Eimeria oocysts in a dose dependent manner as compared to both control groups. V. vinifera extract also damaged the morhology of oocysts in terms of shape, size and number of sporocysts.

Abstract:

The quality of grapes is determined above all by the contents of the primary and secondary metabolites. The primary metabolites involve sugars and organic acids, and just these compounds are dealt with in this study. Its objective was to analyse and critically evaluate the primary metabolites in new interspecific varieties and, based on a comparison with European varieties of grapevine (Vitis vinifera L.), to find out the similarities and also possible differences between them. The study evaluates and compares 4 conventional varieties of Vitis vinifera with 11 new interspecific cultivars. The contents and compositions of the individual sugars and acids were estimated by means of the HPLC method. Most of these varieties belong to the group with either medium or low content of malic acid, i.e. with a medium to high β ratio. This corroborates the similarity of interspecific varieties to those of V. vinifera. The cluster analysis identified the existence of two interesting groups of varieties: the first one involved the varieties Riesling, Nativa, Marlen, and Kofranka while the other group consisted of varieties Blaufränkisch, Blauer Portugieser, and Laurot. This observation also indicates similarity between Vitis vinifera L. varieties and interspecific cultivars and demonstrates that the contents of the primary metabolites (i.e. sugars and organic acids) are also comparable.

The pre-acclimatization stage can be used to improve micropropagation protocols and increase the yield of produced plants. The influence of sucrose and photon flux density (PFD) levels on the acclimatization of in vitro-grown 'VR043-43' (Vitis vinifera x Vitis rotundifolia) grapevine rootstocks was evaluated. Rooted shoots were obtained from 4-week-old in vitro shoots cultivated in QL (Quoirin and Lepoivre, 1977) culture medium supplemented with 15, 30 and 45 g L-1 of sucrose. The experiment was kept in a 25 ± 2ºC growth room, under 16-h photoperiod and PFD of 18 µmol m-2 s-1 or 43 µmol m-2 s-1. Plants were transferred to an intermittent misting system greenhouse for 10 d followed by 20 d of once-a-day watering routine using a handheld hose. Plant height was influenced by sucrose concentration, and shoots produced on media supplemented with 30 g L-1 sucrose were the tallest (5.0 cm). The largest leaf area was obtained with 31.3 g L-1 of sucrose, under the PFD of 43 µmol m-2 s-1 (13.3 cm²). Absence of sucrose in the culture medium led to a significant reduction in leaf area at both PFDs. Shoot (aerial part) dry matter was largest when 30 or 45 g L-1 of sucrose (17.5 and 16.7 mg per plant, respectively) were used. Microcuttings rooted in all sucrose concentrations tested. The highest survival percentage (100%) during ex vitro acclimatization was obtained for shoots cultured in media supplemented with 45 g L-1 of sucrose under both PFDs tested.

Abstract:

Grape phylloxera, Dactulosphaira vitifoliae Fitch., is one of most destructive insect pest of cultivated grapes (Vitis vinifera L.) worldwide. Phylloxera was the cause of incomparable structural changes in European viticulture. It also led to the usage of new biotechnology – rootstocks for grape varieties. The direct damage is related to phylloxera feeding of roots and leaves. Rootstocks bred solely with American Vitis spp. parentage allow little or none of phylloxera related root damage that is seen on Vitis vinifera. Rootstocks with partial Vitis vinifera parentage may also confer a high level of grape phylloxera resistance, but this resistance is not durable. Rootstock was evaluated under laboratory conditions and with pot trials. Resistance against phylloxera at roots and leaves was evaluated. Highest resistance degree was proved for variety Börner. Good resistance was found for most of tested rootstock varieties. Very good resistance have SO4 PO 0/7 and Craciunel 2 PO 0/6. It is interesting, that hybrid Kl×SO4 has also relatively good resistance. This promising franco-american needs further examination thanks to its good growing properties. After long time, this research offers new results about rootstock and phylloxera interactions under conditions of Southern Moravia.

Abstract:

The interest towards nutraceuticals able to counteract drug side effects is continuously growing in current chemotherapeutic protocols. In the present study, we demonstrated that smoothies containing mixtures of Citrus sinensis and Vitis vinifera L. cv. Aglianico N, two typical fruits of the Mediterranean diet, possess bioactive polyphenols that protect cardiomyocytes against doxorubicin-induced oxidative stress. The polyphenolic extracts isolated from Citrus sinensis- and Vitis vinifera-based functional smoothies were deeply characterized by Liquid Chromatography-Mass Spectrometry methods. Subsequently, the functional smoothies and relative mixtures were tested to verify their ability to affect cellular viability and oxidative stress parameters in embryonic cardiomyocyte cells (H9c2), and human breast adenocarcinoma cell line (MCF-7) exposed to doxorubicin. Interestingly, we found that the mix resulting from Citrus sinensis and Vitis vinifera association in ratio 1:1 was able to reduce cardiomyocytes damage induced by anthracyclines, without significantly interfering with the pro-apoptotic activity of the drug on breast cancer cells. These results point out the potential use of vegetable smoothies as adjuvants functional foods for chemotherapeutic anticancer protocols.

Abstract:

Hybridizations between seedless Vitis vinifera L. genotypes and V. rotundifolia (Michx.) were made specifically to introgress the seedless trait into the disease-resistant background of V. rotundifolia. The seedless, gynoecious P79-101 was hybridized with three V. rotundifolia parents, producing a total of 102 ovules. From these ovules, 44 embryos developed, producing 20 plants. Isozyme analyses and morphological traits confirmed that 19 of the plants were hybrids. Sixteen were planted in an experimental vineyard at California State Univ. Fresno. One seedling, C41-5, produced seedless fruit that appeared to be stenospermocarpic based on fruit and aborted seed size. Fruit weight was slightly less than that of `Thompson Seedless' (stenospermocarpic) and at least twice that of parthenocarpic fruit of `Black Corinth' and C41-7, a seeded hybrid with many parthenocarpic fruit. Aborted seeds of C41-5 were larger than, but not significantly different from, those of `Thompson Seedless', while parthenocarpic fruit from `Black Corinth' and C41-7 had aborted seeds that were smaller than those of C41-5. Seed weight of C41-7 averaged almost 10 times that of aborted C41-5 seeds. This is the first report of a stenospermocarpic, seedless hybrid of V. vinifera × V. rotundifolia.
