Candidatus Liberibacter solanacearum (Lso) is bacterium transmitted by psyllids to Solanaceae and Apiaceae plants. So far, Lso is found in Europe affecting Apiaceae. In the Mediterranean region, Bactericera trigonica is the only known vector of Lso, but the leek-onion psyllid Bactericera tremblayi is another widespread psyllid and potential vector of Lso. Commonly, carrot, leek and potato are c...
Pseudomonas syringae pv. porri, the causative agent of bacterial blight in leek (Allium porrum), is increasingly frequent causing problems in leek cultivation. Because of the current lack of control measures, novel bacteriophages were isolated to control this pathogen using phage therapy. Five novel phages were isolated from infected fields in Flanders (vB_PsyM_KIL1, vB_PsyM_KIL2, vB_PsyM_KIL3,...
BACKGROUND Spray volume can influence the amount of free water on the leaf surface and subsequently the ability of entomopathogenic nematodes (EPNs) to move. In this study, an investigation was made of the effect of spray volume (548, 730 and 1095 L ha(-1) ) on the deposition, viability and infectivity of EPNs against Galleria mellonella on savoy cabbage, cauliflower and leek. RESULTS Increas...
Persian shallot, also called leek (Allium ampeloprasum), is a monocotyledon plant of the lily family (Liliaceae). It belongs to the genus Allium, has a characteristic taste and morphological features, making it to be considered as one of the popular herbal medicine. This research was conducted with the purpose of obtaining optimal conditions for tissue culture of Persian shallot and comparing i...
background: the sources of radioactivity in the environment have natural, terrestrial and extraterrestrial, and anthropogenic origins. plants may get radioactive nuclides in two ways: (i) by the deposition of radioactive fallout, (ii) by absorption from the soil. materials and methods: the concentrations of the natural radionuclides (226ra, 228ra, 40k) and the artificial radionuclide (137cs) in...
A rapid multi-residue method was developed for the determination of 20 organophosphorous pesticide residues in leeks by gas chromatography coupled to triple quadrupole mass spectrometry (GC–QqQMS/MS). The method was based on the modified QuEChERS sample preparation method. After microwave pre-treatment, leek samples were extracted with acetonitrile containing acetic acid 0.1% and cleaned by dis...
Leek (Allium porrum) plasma membrane is enriched in phosphatidylserine (PS) by the vesicular pathway, in a way similar to that already observed in animal cells (B. Sturbois-Balcerzak, D.J. Morre, O. Loreau, J.P. Noel, P. Moreau, C. Cassagne [1995] Plant Physiol Biochem 33: 625-637). In this paper we document the formation of PS-rich small vesicles from leek endoplasmic reticulum (ER) membranes ...
Background and objectives: This study was designed to investigate the effect of ethanol extract of Allium ampeloprasum (Leek) leaves on blood lipid profile in rats. Due to the side effects of chemical drugs and social tendency toward herbal medicines, it’s justified to propose new herbal remedies for prevention of cardiovascular disease. Methods: Thirt...
The leek moth, Acrolepiopsis assectella (Zeller), is a newly introduced micro-lepidopteran pest in North America that attacks Allium crops, including onion, leek, and garlic. Eggs are laid on leaves and emerging larvae may cause extensive damage by mining leaves, feeding on leaf surfaces and feeding directly on bulbs. Little is known about existing natural enemies for this pest in North America...
