Odor, Not Performance, Dictates Bemisia tabaci's Selection between Healthy and Virus Infected Plants
Although, insect herbivores are generally thought to select hosts that favor the fitness of their progeny, this "mother-knows-best" hypothesis may be challenged by the presence of a plant virus. Our previous study showed that the whitefly, Bemisia tabaci, the obligate vector for transmitting Tomato yellow leaf curl virus (TYLCV), preferred to settle and oviposit on TYLCV-infected rather than he...
The attention of the profession in this country, was not, I believe, particularly called to the medicinal properties of the Stramonium till Dr Marcet, in an interesting paper, read before the Medical and Chirurgical Society of London, in June 1816, and published in their Transactions *, detailed the ^results of his experience of its use. Storck, it is true, so early as 1762, in a pamphlet publi...
The alkaloid spectra of Datura innoxia plants grown in Egypt and Bulgaria were investigated by GC-MS. Thirty-eight alkaloids were detected in the roots, leaves and fruits of the plants. Five new alkaloids for D. innoxia are reported. Alkaloid spectra of Egyptian and Bulgarian plants differ significantly in respect to their alkaloid composition and main alkaloids accumulated in the plant organs.
The presence of different glutamine synthetase isoenzymes in different Solanaceae plants and their relative antigenicities against antiglutamine synthetase from tomato leaf serum were studied. All the plants tested showed one glutamine synthetase isoenzyme except for Mandragora autumnalis, which showed two, after discontinuous polyacrylamide gel electrophoresis and specific in situ assay. Antig...
Pot experiments were conducted to study the allelopathic effect of Datura stramonium residue on germination and growth characters purslane (Portulaca oleracea L). Experiments set as completely randomized design with four treatments three replications. Results indicated that concentration affect negatively. The lower level induced a stimulatory plant height, leaf area, shoot root, fresh dry weig...
Hairy root cultures were obtained from diploid and induced tetraploid plants of Datura stramonium and analyzed by gas chromatography/mass spectrometry. Twenty alkaloids (19 for diploid and 9 for tetraploid hairy root cultures) were identified. A new tropane ester 3-tigloyloxy-6-propionyloxy-7-hydroxytropane was identified on the basis of mass spectral data. Hyoscyamine was the main alkaloid in ...
