The olive leaf trichomes are multicellular peltate hairs densely distributed mainly at the lower leaf epidermis. Although, non-glandular, they have gained much attention since they significantly contribute to abiotic and biotic stress tolerance of olive leaves. The exact mechanisms by which olive trichomes achieve these goals are not fully understood. They could act as mechanical barrier but th...

background and purpose: pistacia atlantica, which belongs to the anacardiaceae family, grows in the zagrossian region of iran. the aim of this study was to evaluate the antifungal properties of pistacia atlantica and olive leaf extracts against different fungal species. materials and methods: in this study, we assessed the activities of olive leaf extracts and pistacia atlantica leaf and fruit ...

Internally feeding herbivorous insects such as leaf miners have developed the ability to manipulate the physiology of their host plants in a way to best meet their metabolic needs and compensate for variation in food nutritional composition. For instance, some leaf miners can induce green-islands on yellow leaves in autumn, which are characterized by photosynthetically active green patches in o...

Olive leaf spot or peacock spot, caused by the fungal pathogen Spilocaea oleagina, can cause reduced growth and yield in olive trees (Olea eurapaea). Investigations were carried out during 20072010 to measure the prevalence and severity of olive leaf spot in the northern olive growing regions of Iran. The susceptibility of ten cultivars (Amygdalifolia, Blaidy, Koronakei, Mary, Manzanillo, Missi...

Olive oil, an important component of the Mediterranean diet, is rich in polyphenols and is known to possess positive health effects relative to other dietary fats. In addition, the leaves of the olive plant (Olea europaea) contain similar phenolics (oleuropein, luteolin-7-glucoside, apigenin-7-glucoside, verbascoside and hydroxytyrosol) to those of olives and olive oil, although at higher conce...

Calcium elenolate is a multifunctional monoterpene which can be isolated from acid-hydrolyzed aqueous extracts of various parts of olive plants. Viruses tested in this study were: Coxackievirus A21, parainfluenza 3 virus, herpesvirus (MRS), pseudorabies virus, vesicular stomatitis virus, encephalomyocarditis virus, Newcastle virus (GB), poliovirus 1,2,and 3, influenza A virus (PR8), Sindbis vir...

Introduction: Huntington's disease is a neurodegenerative disorder in which an increase in the global oxidative stress and a decrease in the antioxidant defense system are observed. Olea europaea's main phenolic components include oleuropein, dimethyl oleuropein, ligstroside and phenolic oleosides, which can be more than 140 mg per gram of fresh olives and 60-90 mg per gram of dried olive le...
