In the study, the bioactive, physicochemical and antimicrobial properties of koruk juice and dried koruk pomace were investigated. The total phenolic contents of koruk juice and pomace were determined as 1119.670 and 1182.170 mg GAE/L, respectively. Higher DPPH radical scavenging activity found in koruk pomace, which was consistent with total phenolic contents. Organic acid, total sugar and ascorbic acid contents of koruk juice (3.44%, 4.737 g/L and 2.559 mg/100 mL) were higher than koruk pomace (0.19%, 0.866 g/L and 0.242 mg/100 mL). The counts of Total Psychrophilic Aerobic Bacteria and mold-yeast in pomace were determined as 0.694 and 1.016 log CFU/g, respectively, while no growth was observed in koruk juice. Koruk juice and pomace indicated antimicrobial effect on all test microorganisms in the range of 31.3-500.0 µg/mL (Minimum Inhibition Concentration). The most sensitive bacteria to koruk juice were Bacillus cereus, while Pediococcus acidilactici was the most sensitive one to koruk pomace. Koruk juice also showed bactericidal effect on all test cultures at concentration ranging between 250.0 and 500.0 µg/mL (Minimum Bactericidal Concentration), koruk pomace was not showed bactericidal effect on Escherichia coli O157:H7, Salmonella Typhimurium, E. coli and B. cereus. This study demonstrated that the koruk products could be used in food applications as natural antioxidant and antimicrobial substance.

Grapevine (Vitis vinifera L.) is a perennial horticultural crop which is used worldwide for production of wine, table grapes, dried fruits and grape juice. In spite of its importance as a cash crop, the purity of each variety and genetic diversity of this crop has not been identified. The study therefore, was conducted to assess the purity and genetic diversity among and within 10 varieties of grapevines represented by a total of 43 individual plants. By using nine ISSR primers, a total of 56 polymorphic bands were generated. Within variety diversity based on polymorphic bands ranged from 26.79% for Ruby seedless to 73.21% for Alphoncelavallee with a mean of 55.18 %, Neis genetic diversity of 0.089 0.308 with a mean of 0.202, Shannon information index of 0.137–0.445 with a mean of 0.302 and analysis of molecular variation (AMOVA) of 76.767% within varieties were detected. With all diversity parameters, the highest diversity was obtained from Regina, Alphoncelavallee, Syrah and Makutupora white varieties, whereas the lowest was from Ruby seedless. AMOVA showed a 23.23% between varieties variability was less than that of within varieties variation. Varieties differentiation with Fixation index (FST) was 0.23. From Jaccards pairwise similarity coefficient, Makutupora red and Chancellor were most related varieties exhibiting 0.976 meanwhile Queen of vineyard and Ruby seedless were most distantly related varieties with similarity of 0.408. Alphoncelavallee and Makutupora white varieties exhibited the highest genetic diversity. Therefore, these varieties should be considered for further improvement of this species.

The emergence and expression of the YABBY gene family (YGF) coincided with the evolution of leaves in seed plants, and was integral to the early evidence of lamina followed by reproductive development. YGF contains six subclasses, i.e., CRC, INO, FIL, YAB2, YAB3, and YAB5. This study aims to extract the genome sequences of the YGF in Bienertia sinuspersici, an important model plant for single-cell C4 (SCC4), non-Kranz photosynthesis. A comparative genomic analysis was undertaken with Vitis vinefera, Arabidopsis thaliana, Brassica rapa, and Chenopodium quinoa. Six copies of YGF were present in B. sinuspersici and A. thaliana with a single copy of each YGF subgroup. V. vinefera possessed seven copies of YGF with duplicates in FIL and YAB2 subgroups, but no YAB3. B. rapa and C. quinoa after whole genome duplication contained additional copies of YGF. The gene structure and conserved motifs were analyzed among the YGF. In addition, the relative quantification of YGF was analyzed in the leaves, reproductive developmental stages such as the bud, and the pre-anthesis and anthesis stages in B. sinuspersici, A. thaliana, and B. rapa. CRC and INO possessed conserved floral-specific expression. Temporal and perpetual changes in the expression of YGF orthologs were observed in the leaves and reproductive developmental stages. The results of this study provide an overview of YGF evolution, copy number, and its differential expression in B. sinuspersici. Further studies are required to shed light on the roles of YABBY genes in the evolution of SCC4 plants and their distinct physiologies.

Attempts were made to delineate the correlation coefficients of the vine, cluster and berry parameters with yield and quality in to direct and indirect effects in Thompson Seedless grape (Vitis vinifera L.) and its clones, namely Tas-A-Ganesh and 2A clone by Path Coefficient Analysis. Yield was influenced most, directly by cluster weight in Thompson Seedless, while by canes/vine in Tas-A-Ganesh; indirectly by berry diameter via cluster weight in the former variety, while by canes/vine via berries/cluster in the latter. When the negative effects on yield were considered, the direct effect of berries/cluster was highest in Thompson Seedless, while it was of berries/cluster in Tas-A-Ganesh. Among the indirect negative effects, cluster weight through berry diameter was highest in Thompson seedless, but berries/cluster through canes/vine in Tas-A-Ganesh. All the parameters included in the study could determine the yield in 2A clone by only 1.0 per cent, as the residual effect was 0.99. The corresponding residual values were 0.506 for Thompson Seedless and 0.516 for Tas-A- Ganesh.

L’esca est une maladie de dépérissement de la vigne provoquée par des champignons intraxylémiens, dont Phaeomoniella chlamydospora et Phaeoacremonium aleophilum. Nous avons tout d’abord précisé l’influence de facteurs environnementaux tels que la température et le pH sur la croissance des deux champignons et défini des critères cyto-physiologiques permettant leur distinction in vitro. A l’issue de leur étude in planta, dans des boutures infectées sélectivement, nous avons observé que ces agents colonisent des tissus distincts : P. Chlamydospora se développe essentiellement dans les vaisseaux et les fibres xylémiennes alors que P. Aleophilum est détecté préférentiellement dans le protoxylème et la moelle. Ce dernier présente une capacité de dégradation des différentes couches pariétales lignifiées alors que P. Chlamydospora ne désorganise que les parois pectocellulosiques. De plus, des expériences de co-inoculation montrent l’effet synergique des deux champignons dans leur capacité d’envahissement du xylème et d’altération des parois. Sur les sarments et les feuilles de Vitis vinifera cv Ugni blanc nous avons défini des caractéristiques phénotypiques et structurales propres à l’esca, comparativement à celles du black dead arm et de l’eutypiose. Puis, dans les feuilles nous avons mis en évidence l’impact de l’esca sur le glutathion et sur l’expression des gènes d’enzymes participant à son métabolisme, dont des glutathion S-transférases. Au delà des altérations précoces du métabolisme primaire, la teneur et l’état rédox du glutathion et l’expression des glutathion S-transférases représentent des marqueurs de niveau de stress dans la vigne : leur suivi pourrait être un indicateur de l’apparition de la maladie au vignoble
Esca disease is a grapevine damage induced by pathogenic fungi localized in the xylem especially Phaeomoniella chlamydospora and Phaeoacremonium aleophilum. We evaluated the effect of various environmental factors, such as temperature and pH on the development of these two fungal pathogens and determined the corresponding cyto-physiological criteria leading to their in vitro characterization. In selectively infected cuttings we observed that these agents invaded different areas: P. Chlamydospora developed mainly in vessels and fibres whereas P. Aleophilum was detected predominantly in protoxylem and pith areas. Our data also highlighted P. Aleophilum capacity to degrade lignified wall layers whereas P. Chlamydospora only disorganized pectocellulose walls. In addition, co-inoculations of the two fungi showed the synergistic capacity of these two fungi to invade wood and cause cell wall damage. In canes and leaves of Vitis vinifera cv Ugni blanc we determined specific phenotypic and structural features of the esca disease and compared this to those of black dead arm and eutypa dieback. We observed the impact of esca on glutathione in leaves, focusing on gene expression corresponding to enzymes involved in its metabolism, as well as glutathione S-transferases. Apart from an initial perturbation in primary metabolism, levels and redox state of glutathione and expression of glutathione S-transferases can be considered as stress markers in vine: their detection might constitute an early indicator for infection of grapevine by esca disease in the field

L'implantation du Fer Servadou dans le sud-ouest de la France est assez importante et en constante augmentation. A ce jour, aucune étude n'a été menée sur ce cépage, mais la connaissance de ces aptitudes viticoles et oenologiques représente un enjeu important pour les viticulteurs de la région. Dans le but de mieux comprendre la physiologie de la nutrition minérale du Fer Servadou, nous avons mis en place une expérimentation en culture hors-sol. Les résultats montrent que le Fer Servadou présente une capacité d'absorption élevée pour le K et le Mg mais faible pour le Ca et que l'antagonisme Ca-Mg est marqué sur ce cépage. Aussi, le clone 556 présente une capacité d'absorption plus forte pour le K, mais plus faible pour le Mg que le clone 420. Dans le but d'étudier les relations cépage/terroir/qualité des vins, nous avons effectué un suivi agronomique et œnologique sur un réseau de parcelles de Fer Servadou ; l'ensemble des données acquises ont fait l'objet d'analyses en composantes principales. Quatre groupes de terroirs ont été identifiés selon le type de sol et le climat. Sur les sols non carbonatés, l'alimentation potassique est importante, les baies de raisin sont grosses et peu acides et les vins sont peu colorés, assez fruités, mais peu complexes. Inversement, sur les sols carbonatés, l'alimentation calci-magnésienne est importante, les raisins sont riches en acides organiques mais pauvres en potassium, et les vins acides, colorés et complexes. De plus, sur les terroirs les plus froids, la maturation des raisin est plus tardive, les raisins et les vins sont plus acides, plus riches en anthocyanes et polyphénols, et les vins plus riches en IBMP et plus complexes
Plantations of Fer Servadou in South West France are significant and constantly growing. So far, no study has been made on this variety but the knowledge but mastery of its varied characteristics is of the utmost importance for the regions' wine growers. In order to allow us to understand the mineral nutrition physiology of FS more fully, we carried out an experiment in hydroponic culture under controlled conditions. Results show that Fer servadou has a high capacity for K and Mg uptake but low for Ca uptake, and the Ca-Mg antagonism is strong for this variety. However, clone 556 presents a capacity higher for K uptake but lower for Mg uptake than clone 420. In order to study the relationship between the vine/terroir/wine quality, we carried out an agronomic and enological follow up on plots of Fer servadou and the total data obtained have been analysed by several Principal Components Analysis. Four groups of terroirs have been identified depending of the soil type and the climate. On the low-carbonated soils, the potassium nutrition is high, the grapes have large berries with a lack of acidity and the wines have weak color, is quite fruity but lacking in complexity. On the other hand, on the high-carbonated soils, calcium and magnesium nutrition is important and the grapes are rich in tartaric and malic acid yet poor in potassium and the wines are acid, with good color and complex. Moreover, on the coolest terroirs, grapes mature later and both grapes and wines have higher acidity, are richer in anthocyanins, polyphénols and the wines have more IBMP, and are more complex

La Vigne est principalement cultivée pour ses baies de raisin, qui ont un intérêt économique considérable. Afin de mieux comprendre les mécanismes impliqués dans l’accumulation des sucres, nous avons identifié trois transporteurs de monosaccharides : VvHT1 (Vitis vinifera hexose transporter 1), VvHT2 et VvHT6. VvHT1 a été caractérisé dans le système hétérologue levure comme un transporteur de glucose membranaire. En conjuguant des techniques d’hybridation in situ et d’immunolocalisation nous avons pu localiser VvHT1 à l’interface du complexe cellule criblée/cellule compagne. Les tentatives de caractérisation fonctionnelle de VvHT2 et VvHT6 dans la levure ayant échoué, nous avons opté pour de la transgenèse. Ainsi des expériences d’expression transitoire dans les protoplastes de plantes ont permis de localiser VvHT2-GFP et VvHT6-GFP sur le tonoplaste. Afin de caractériser VvHT2 et VvHT6, des mesures d’absorption de sucres radiomarqués réalisées sur des cellules transgéniques de Vigne surexprimant VvHT2 révèlent un efflux de glucose par rapport au contrôle, et celles surexprimant VvHT6 révèlent un influx de glucose plus important comparativement au contrôle. Dans le but de mieux comprendre la régulation de ces transporteurs au cours du développement de la baie, nous avons cloné et analysé leurs promoteurs. Des expériences de RT-PCR semi-quantitative réalisées après traitements de cellules de Vigne par différents stimuli ont révélé que certains des éléments identifiés par analyse in silico sur les promoteurs pourraient être fonctionnels. Enfin, des constructions promoteursVvHT::GUS ont été préparées et utilisées pour localiser l’expression de VvHT2 et VvHT6 in planta
Grapevine is mainly cultivated for its berries, which are of major economical interest. In order to better understand the mechanisms involved in sugar accumulation, we identified three monosaccharide transporters : VvHT1 (Vitis vinifera hexose transporter 1), VvHT2 et VvHT6. VvHT1 have been characterized in heterologous yeast system as a plasma membrane glucose transporter. The combine use of in situ hybridization and immnunogold labelling, allowed us to localize VvHT1 at the sieve element – companion cell interface. As attempts to express VvHT2 and VvHT6 in yeast failed, we decided to use transgenic approach. Thus, transient expression experiments in plant protoplasts allowed us to localize both VvHT2-GFP and VvHT6-GFP at the tonoplast. In order to characterize VvHT2 and VvHT6, sugar uptake experiments were performed on the transgenic cells overexpressing either VvHT2 or VvHT6. The results obtained revealed that the overexpression of VvHT2 resulted in a glucose influx of less importance in comparison to the control and that the overexpression of VvHT6 was responsible of a more important glucose influx compared to the control. In order to better understand the regulation of the expression of these transporters during grape berry development, we cloned and analyzed the corresponding promoters. Semi-quantitative RT-PCR experiments conducted on grape cell suspensions after different treatments suggested that some of elements identify on these promoters by in silico analysis could be functional. Finally, promoterVvHT::GUS constructs were produced and allowed the localisation of VvHT2 and VvHT6 expression in planta
