Despite senescence-induced chlorophyll depletion in plants has been widely studied, the enzymatic background of this physiologically regulated process still remains highly unclear. The purpose of this study was to determine selected biochemical properties of partially purified fractions of chlorophyllase (Chlase, chlorophyll chlorophyllido-hydrolase, EC 3.1.1.14) from leaves of three Prunus spe...

Sour cherry cv. Marasca is Dalmatian cultivar from XVI century. Cultivation is limited on the north and central part of Dalmatia and on the part of the islands, where it achieves the best quality of fruit, high content of dry matter and sugar respectively, agreeable aroma and intense color. Sour cherry cv. Marasca is source of biologically active ingredients, organic and inorganic compounds, di...

Background and objective: Peel oil and juice of citrus fruits have furocoumarin (Psoralen) that can induce phytophotodermatitis. If the reaction is mild, then only hyperpigmentation (Without itching, burning, erythema, vesicle and bullae, formation) may occur. The objective of this study was to describe the patients with hyperpigmentation of back of the hands. Materials and Methods: Thirty-two ...

Endophytic fungi are beneficial fungi to their host plants and help them to endure biotic and abiotic stresses with different methods. In order to identify some endophytic fungi of sour cherry trees, healthy plant samples including twigs and leaves were collected from several provinces of Iran. A total number of 176 isolates were obtained and studied taxonomically. Based on morphological featur...

Gametophytic self-incompatibility (GSI) is an outcrossing mechanism in flowering plants that is genetically controlled by 2 separate genes located at the highly polymorphic S-locus, termed S-haplotype. This study characterizes a pollen part mutant of the S(1)-haplotype present in sour cherry (Rosaceae, Prunus cerasus L.) that contributes to the loss of GSI. Inheritance of S-haplotypes from reci...

BACKGROUND Tart Montmorency cherries have been reported to contain high levels of phytochemicals including melatonin, a molecule critical in regulating the sleep-wake cycle in humans. PURPOSE The aim of our investigation was to ascertain whether ingestion of a tart cherry juice concentrate would increase the urinary melatonin levels in healthy adults and improve sleep quality. METHODS In a ...

recently great afford have focused on the production of food and beverages which are rich in phenolic and antioxidant components. the epidemiology investigations have proved that the regular composition of food and beverages are richer in phenolic and antioxidant components can strongly decrease the cardiovascular disease. this was done after the preparation of components such as soymilk mixed ...

The objective of this study is to investigate the influence of cultivar and industrial processing on total polyphenols, anthocyanins, hydroxycinnamic acids and antioxidant activity in concentrated sour cherry (Prunus cerasus L., cvs. Marasca and Oblačinska) juices. Samples were collected during four processing steps: from fresh fruit prior to processing, then from pressed, filtered and concentr...

BACKGROUND Long distance running causes acute muscle damage resulting in inflammation and decreased force production. Endurance athletes use NSAIDs during competition to prevent or reduce pain, which carries the risk of adverse effects. Tart cherries, rich in antioxidant and anti-inflammatory properties, may have a protective effect to reduce muscle damage and pain during strenuous exercise. Th...

Tetraploid sour cherry (Prunus cerasus) has an S-RNase-based gametophytic self-incompatibility (GSI) system; however, individuals can be either self-incompatible (SI) or self-compatible (SC). Unlike the situation in the Solanaceae, where self-compatibility accompanying polyploidization is often due to the compatibility of heteroallelic pollen, the genotype-dependent loss of SI in sour cherry is...
