Domestication of crop plants selects for numerous traits that often distinguish them dramatically from their wild progenitors. In some cases, these modifications lead to increased herbivory, by enhancing their attractiveness to herbivorous insects or reducing the efficiency of natural enemies, or both. This study investigated the effects of fruit enlargement on the olive (Olea europaea L.), the...

Analyzing genome structure in different species allows to gain an insight into the evolution of plant genome size. Olive (Olea europaea L.) has a medium-sized haploid genome of 1.4 Gb, whose structure is largely uncharacterized, despite the growing importance of this tree as oil crop. Next-generation sequencing technologies and different computational procedures have been used to study the comp...

Olive fly (Bactrocera oleae R.) is the most harmful insect pest of olive (Olea europaea L.) which strongly affects fruits and oil production. Despite the expanding economic importance of olive cultivation, up to now, only limited information on plant responses to B. oleae is available. Here, we demonstrate that olive fruits respond to B. oleae attack by producing changes in an array of differen...

Eco-friendly synthesis of nanoparticles, which is one of the most advanced evergreen branches of nanoscience for biomedical application. This synthesis is non toxic and very low cost are major features of production it further attractive prospective option for biomedical field and elsewhere. In this investigation, the anticancer potentiality of AuNPs, stabilized with Olea europaea L was studied...

BACKGROUND A new subcutaneous specific immunotherapy (SCIT) product adsorbed on aluminium hydroxide has been developed with a short and simplified up-dosing phase, containing a biologically standardized allergen pollen extract from Olea europaea. OBJECTIVE To assess the tolerability profile of the updosing phase and its immunological effect, in terms of specific IgG4 and IgE levels and immedi...

BACKGROUND Phylogenetic and phylogeographic investigations have been previously performed to study the evolution of the olive tree complex (Olea europaea). A particularly high genomic diversity has been found in north-west Africa. However, to date no exhaustive study has been addressed to infer putative polyploidization events and their evolutionary significance in the diversification of the ol...

pollen grains as well as whole plants of four olive (olea europaea l.) cultivars were screened for nacl salinity stress. different vegetative and physiological indexes of the cultivars were analyzed. leaf and root na/k ratio as well as stomatal resistance of plants exposed to salinity proved to be appropriate indexes of whole plant response to salt stress. whereas, in vitro pollen germination p...

The objective of this study is the evaluation anticoagulant activity polyphenols obtained from olive extracts (Olea europaea L.) Of margines two varieties cultivated at Khenchela (East Algeria) , first one souidi Chacher and second chemlal Baghai. physicochemical characteristics studied showed a difference in water content, total solid content (dry matter), suspension, potential hydrogen, espec...

The leading olive variety in Slovenia is "Istrska belica" (Olea europaea L.), which currently represents 70% of all olive trees in productive orchards. Paternity analysis based on microsatellite markers was used for genotyping and identification of the potential pollen donors of "Istrska belica" and for assessing the proportion of self-fertilization in monovarietal olive orchards in the Slovene...

Storage at 3 and 18 °C of 'Arbequina' olives (Olea europaea L.) cultivated in hedgerows and harvested manually or mechanically (wine grape harvester) was tested. Fruit characteristics and oil quality were monitored. Mechanical harvesting caused internal fruit damage that induced its rapid softening and decay, but also facilitated obtaining higher amounts of oil, which suffered a rapid deteriora...
