The ligandin activity of specific glutathione S-transferases (GSTs) is necessary for the transport of anthocyanins from the cytosol to the plant vacuole. Five GSTs were purified from Vitis vinifera L. cv. Gamay Fréaux cell suspension cultures by glutathione affinity chromatography. These proteins underwent Edman sequencing and mass spectrometry fingerprinting, with the resultant fragments align...

Different lengths of the promoter of grape (Vitis vinifera) VvHT1 (Hexose Transporter 1) gene, which encodes a putative hexose transporter expressed during the ripening of grape, have been transcriptionally fused to the beta-glucuronidase reporter gene. In transgenic tobacco (Nicotiana tabacum) transformed with these constructs, VvHT1 promoters were clearly responsible for the sink organ prefer...

Table grape is a non-climacteric fruit, very sensitive to water loss and gray mold during postharvest handling storage. The aim of this work was evaluate the effects modified atmosphere packaging chitosan treatment on quality sensorial parameters minimally processed cv. ‘Italia’ table cold storage (14 days at 5 °C) shelf-life (7 14 plus 20 °C), reproducing retail sales condition. Our data showe...

Berry diameter was monitored during dry-down and rewatering cycles and pressurization of the root system of Vitis vinifera (cv. Merlot) and Vitis labruscana (cv. Concord) to test changes in xylem functionality during grape ripening. Prior to veraison (onset of ripening), berries maintained their size under declining soil moisture until the plants had used 80% of the transpirable soil water, beg...

The experiment was carried out in nursery of Al-Musaib technical college 2020 season to know the effect adding Urea fertilizer three levels 0, 5 and 10 g. seddling-1, spraying by NATURWIN fertilizer, also 20 ml /L-1 on vegetative chemical characterizes grape seedling, cv. Kamali. results showed treatment Kamli urea seedling-1 concentration significant increase all characterizes, stem length (cm...

The research was carried out at University of Belgrade Faculty Agriculture experimental station “Radmilovac” on table grape Victoria cv with aim to improve quality and consideration the introduction these ampelographic measures in regular grapevine growing. included two treatments berry thinning (thinning bunch tip - BtT first lateral wink -BtW), girdling (G) control (C). Combined effect were n...
