Strawberries are a common and important fruit in the Mediterranean diet because of their high content of essential nutrients and beneficial phytochemicals, which seem to have relevant biological activity in human health. Among these phytochemicals, anthocyanin and ellagitannins are the major antioxidant compounds. Although individual phytochemical(More)
OBJECTIVE We wanted to determine the total antioxidant capacity (6-hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid equivalent antioxidant assay; TEAC) of different species and cultivars (strawberry and apple) and to characterize the TEAC among fruits of the same varieties (peach and apricot) but grafted on different rootstocks. METHODS The study was(More)
BACKGROUND Efficient transformation and regeneration methods are a priority for successful application of genetic engineering to vegetative propagated plants such as grape. The current methods for the production of transgenic grape plants are based on Agrobacterium-mediated transformation followed by regeneration from embryogenic callus. However, grape(More)
The different types of organogenic (roots and adventitious shoots) and callus formation responses of leaves from 30-day-old proliferating shoots of different Fragaria spp. genotypes were studied in response to MS medium supplemented with 4.54 μM 1-phenyl-3-(1,2,3-thiadiazol-5-yl) urea (thidiazuron; TDZ) alone and in combination with 0.98 μM indole-3-butyric(More)
BACKGROUND AND AIM Free radicals are implicated in the aetiology of gastrointestinal disorders such as gastric ulcer, colorectal cancer and inflammatory bowel disease. Strawberries are common and important fruit due to their high content of essential nutrient and beneficial phytochemicals which seem to have relevant biological activity on human health. In(More)
Strawberries are an important fruit in the Mediterranean diet because of their high content of essential nutrients and beneficial phytochemicals, which seem to exert beneficial effects in human health. Healthy volunteers were supplemented daily with 500 g of strawberries for 1 month. Plasma lipid profile, circulating and cellular markers of antioxidant(More)
Exposure to UV-A radiation is known to induce discrete lesions in DNA and the generation of free radicals that lead to a wide array of skin diseases. Strawberry (Fragaria × ananassa) contains several polyphenols with strong antioxidant and anti-inflammatory activities. Because the major representative components of strawberry are anthocyanins, these may(More)
Zygotic embryo and shoot tip explants of Phoenix canariensis were cultured on MS (1962) basal medium supplemented with 100 μM Picloram and 9.5 μM kinetin or 10.8 μM or 45.25 μM 2,4-dichlorophenoxyacetic acid (2,4-D) and 9.8 μM N6-(2-isopentenyl) adenine (2iP). These explants after 12 weeks in darkness at 28 °C, produced embryogenic callus with very compact,(More)
In the last few years the nutritional value of fruit has been widely studied and requested by the consumers, especially for protection against cardiovascular events, cancer and others as well as for the general health benefits it can provide. These benefits can be ascribed mainly to the Total Antioxidant Capacity (TAC) of fruit which is determined by a(More)
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(More)
