The dynamics of Xylophilus ampelinus were studied in Vitis vinifera cv. Ugni blanc using gfp-marked bacterial strains to evaluate the relative importance of epiphytic and endophytic phases of plant colonization in disease development. Currently, bacterial necrosis of grapevine is of economic
Three major grapevine trunk diseases, esca, botryosphaeria dieback and eutypa dieback, pose important economic problems for vineyards worldwide, and currently, no efficient treatment is available to control these diseases. The different fungi associated with grapevine trunk diseases can be isolated
Very short exposures of embryogenic calli of Vitis vinifera cv. Superior Seedless grape plants to diluted cultures of Agrobacterium resulted in plant tissue necrosis and subsequent cell death. Antibiotics used for Agrobacterium elimination or as plant selectable markers were not responsible for this
Fungicides in the quinone outside inhibitor class (QoI, also referred to as strobilurins, FRAC group 11) are relied upon for management of a wide range of diseases, including anthracnose, black rot, downy mildew, and powdery mildew on grape. In June 2012, a grape grower from Anderson County in
The spatial distribution of vine plants contaminated by Xylophilus ampelinus, the agent responsible for bacterial necrosis, was studied over a 5-year period within two vineyards in the Cognac area. Both vineyards were planted with Vitis vinifera cv. Ugni blanc but were different in age and agronomic
Polyphenols contained in FGM from Negroamaro (N) and Koshu (K) Vitis vinifera have been shown to exhibit several immunomodulating activities. For instance, mice affected by experimental colitis when administered with K-FGM showed an attenuation of the inflammatory process. In murine asthma, K-FGM
OBJECTIVE
The interaction between the gall-forming grapevine parasite, phylloxera, and the susceptible grapevine species Vitis vinifera was investigated.
METHODS
Phylloxera and grapevines were cocultivated using both potted and micropropagated grapevines. Development of nodosities on primary roots
Leaf and shoot distortions and retarded shoot growth in Vitis vinifera L. prevalent in Australian vineyards in early spring, were investigated in replicated field experiments over 3 yrs. Leaf distortion and retarded shoot growth were identified as damage due to feeding of extremely high populations
Solar ultraviolet radiation (UV) is a major cause of non-melanoma skin cancer in humans. Photochemoprevention with natural products represents a simple but very effective strategy in the management of cutaneous neoplasia. The study investigated the protective activity of Calluna vulgaris (Cv) and
BACKGROUND
Protective effects of Vitis Vinifera seed aqueous extract (VVSAE) against pancreatic dysfunctions and elevation of oxidative stress, inflammation and apoptosis in the pancreas in diabetes were investigated. Histopathological changes in the pancreas were examined under light
Downy mildew resistance is a quantitative trait in grapevines of the genus Vitis. The grapevine 'Bianca' has retained resistance, originally present in its North American ancestors, through several cycles of backcrossing with susceptible cultivars of Vitis vinifera followed by phenotypic selection.
The medicinal properties of grapes (Vitis vinifera L.) are well known since ancient times. Ethnobotanical grape preparations, like the Ayurvedic Darakchasava are used as cardiotonic and for the treatment of cardiovascular diseases. Dried grape products are also applied in Iranian BACKGROUND
Fruits of Vitis vinifera L., commonly known as grapes, are largely consumed worldwide because of their high nutritional and medicinal benefits.
OBJECTIVE
The present study investigated effects of V. vinifera fruits in ovalbumin-induced animal model of bronchial asthma.
METHODS
Male wistar
Grapevine trunk diseases (Eutypa dieback, esca and Botryosphaeria dieback) are caused by a complex of xylem-inhabiting fungi, which severely reduce yields in vineyards. Botryosphaeria dieback is associated with Botryosphaeriaceae. In order to develop effective strategies against Botryosphaeria
Several years ago, Vitis vinifera cv. Red Globe vines (over 6 years old), started to show disease symptoms approximately 10 weeks after bud break. Symptoms first appeared on the leaves at the base of the shoots and then spread to other leaves, continuing to appear throughout the growing season. Two
