Cultivar characterization for fruit trees certification requires fast, efficient and reliable techniques. Microsatellite markers (SSR) were used in the molecular characterization of 29 Prunus spp. rootstocks. The DNA from the rootstocks was analyzed using five pre-selected SSR primers (UDP96-005, UDP96-008, UDP96013, UDP96-18 and UDP98-414) and revealed 81 alleles, which allowed each genotype t...

Background The peach Lipid Transfer Protein (LTP), Pru p 3, is considered to be a major allergen in peach allergy, but sensitization to it is almost always present in LTP-syndrome. Thus, detection of Pru p 3 specific IgE (sIgE) is frequent in routine peach and/or LTP allergy diagnosis. ImmunoCAP is one of the most frequent immunoassays for specific IgE detection, with a 0.1kU/L detection limit,...

Cold storage is extensively used to slow the rapid deterioration of peach (Prunus persica L. Batsch) fruit after harvest. However, peach fruit subjected to long periods of cold storage develop chilling injury (CI) symptoms. Post-harvest heat treatment (HT) of peach fruit prior to cold storage is effective in reducing some CI symptoms, maintaining fruit quality, preventing softening and controll...

Breeding programs aiming at developing new nematode-resistant rootstocks are important because current rootstocks with adequate nematode resistance tend to have other undesirable viticultural characteristics (excessive vigor, excessive potassium uptake, poor resistance to phylloxera, rooting difficulty, inadequate zinc absorption). In this paper the authors develop a technique for evaluating re...

Modification of anthocyanin plays an important role in increasing its stability in plants. Here, six anthocyanins were identified in peach (Prunus persica), and their structural diversity is attributed to glycosylation and methylation. Interestingly, peach is quite similar to the wild species Prunus ferganensis but differs from both Prunus davidiana and Prunus kansueasis in terms of anthocyanin...

Extensive studies on the dry fruits of the model plant arabidopsis (Arabidopsis thaliana) have revealed various gene regulators of the development and dehiscence of the siliques. Peach pericarp is analogous to the valve tissues of the arabidopsis siliques. The stone (otherwise called pit) in drupes is formed through lignification of the fruit endocarp. The lignified endocarp in peach can be sus...

BACKGROUND In the coming years, a nutraceutical food may provide both physical and mental benefits that are commonly attributed to the active components of the food. OBJECTIVE In this study, we determined the nutrient and mineral contents, sensory properties, and physical and chemical characteristics of ice creams manufactured using peach fibre at different concentrations (1 and 2%). METHOD...

Paclobutrazol (Pbz) is a triazol that effectively inhibits vegetative growth in peach. Changes in mineral element concentration have been generally found. However, uneven distribution of the elements in the soil may partially account for these differences. To ascertain these effects, an experiment was designed under controlled conditions, in which sugar beet, used as a model plant, was grown hi...

BACKGROUND AND OBJECTIVE The allergenic potential of proteins can be altered under various physicochemical conditions. Glutathione (GSH) is a reducing agent that is used as an antioxidant in food products. We aimed to characterize the natural folding of peach proteins and test the allergenicity of reduced and natural Pru p 3, the major peach allergen. METHODS Pru p 3 was purified from peach, ...
