petri disease is responsible for grapevine decline and occurs wherever grapevines (vitis vinifera) are cultivated. phaeoacremonium species are among the principal hyphomycetes associated with petri disease. during 2009, a field survey was conducted throughout different vineyards in the fars province of iran in order to determine the fungal pathogens associated with the vine decline observed in ...

The effects of induced mutation produced by five different doses of gamma irradiation (20, 25, 30, 40, and 45 Gy) were determined using molecular approaches in Vitis vinifera cultivars, namely Thompson Seedless (Sultani Çekirdeksiz) (progenitor of seedless vinifera variety) and Kalecik Karasi (one of the best quality wine grape variety of Turkey). Mutant candidates were selected through morphol...

Traditional herbal plants have played a major role in healing and preventive medicine for hundreds of years. Berberis vulgaris L. var. asperma is an indigenous seedless barberry fruit variety in Iran which is commonly utilized as additive in food and has been documented to possess several pharmacological properties of medical importance. This preliminary study investigated the anticancer activi...

Compact binary coalescences are a promising source of gravitational waves for second-generation interferometric gravitational-wave detectors. Although matched filtering is the optimal search method for well-modeled systems, alternative detection strategies can be used to guard against theoretical errors (e.g., involving new physics and/or assumptions about spin or eccentricity) while providing ...

Grape (Vitis vinifera) yield is largely dependent on the fecundity of the cultivar. The average number of inflorescences per shoot (i.e. shoot fruitfulness) is a trait related to fecundity of each grapevine. Berry number and weight per bunch are other features affecting grape yield. An ovule-specific auxin-synthesizing (DefH9-iaaM) transgene that increases the indole-3-acetic acid content of gr...

Late-season dehydration is known as a type of berry shrivel and it often associated with wine grapes. This study different from other studies focuses on seedless grape cv. Sultan 7 (Vitis vinifera L.) aims to determine the effects pruning levels (90, 150, 180 buds per vine), leaf removal (LR) (25%, 50% shoot) treatments vine yield, number harvested clusters. Additionally, we aim find unhealthy ...

BACKGROUND The phytohormone gibberellic acid (GA3) is widely used in the table grape industry to induce seedlessness in seeded varieties. However, there is a paucity of information concerning the mechanisms by which GAs induce seedlessness in grapes. METHODOLOGY/PRINCIPAL FINDINGS In an effort to systematically analyze the cause of this GA3-induced seed abortion, we conducted an in depth char...

We used molecular markers associated with seedlessness in grapes, namely SCC8, SCF27 and VMC7f2, to improve the efficiency of seedless grapevine breeding via marker assisted selection (MAS). DNA from 372 F₁ hybrid progeny from the cross between seeded "Alphonse Lavallée" and seedless "Sultani" was amplified by PCR using three markers. After digestion of SCC8 marker amplification products by res...

In the present work, the seedless, highly aligned and vertical ZnO nanorods in 3 dimensions (3D) were grown on the nickel foam substrate. The seedless grown ZnO nanorods were characterised by field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD) techniques. The characterised seedless ZnO nanorods in 3D on nicke...

Grapevine leafroll disease (GLD) is the most important disease of grapevines, occurring in every grape-growing country (Martelli, 1993). GLD affects grapevines adversely, where it delays the maturation of the berries, decreases the accumulation of sugars and affects the overall yield and quality of the fruit (Over de Linden and Chamberlain, 1970). This negatively impacts on the wine industry, w...
