It has been shown that Atropa belladonna acts as a symptomless carrier of Hyosoyamus Virus I. Some symptoms caused by this virus on other solanaceous plants are described.A naturally occurring virus complex in Hyoscyamus niger was found to consist of Solanum Virus I (potato virus X) and Brassica Virus I. During the course of the investigation it was found that potato virus X forms local lesions on the cotyledons of ridge cucumber without systemic infection and that Brassica Virus I behaves similarly on the inoculated leaves of Nicotiana sylvestris.

Solanaceae Family

Tropane alkaloids are a group of secondary metabolites occurring naturally in Solanaceae family as Atropa belladona, Datura stramonium, Mandragora officinalis, and Hyoscyamus niger. These molecules have valuable therapeutic applications, for example, atropine and hyoscyamine are utilized as antimuscarinic besides being stomach and intestinal diseases drugs. Plants of the Solanaceae family can provide a natural yet less expensive source of these compounds. Hitherto, in order to emphasize these metabolites biosynthesis, D. stramonium seeds were irradiated using a cobalt-60 source of gamma rays of 5 to 80 Gy and germinated in vitro on MS medium in growth controlled chamber. Mutagenesis of D. stramonium seeds was attempted aiming at obtaining plants from in vitro source that are genetically variable for enhancing the biosynthesis of secondary metabolites, namely alkaloids. Results indicated that D. stramonium seeds exhibited a good radiosensitivity and the mutagen damage index GR (30-50) for D. stramonium was determined at 80 Gy. The Characterization of alkaloids (Atropine and hyoscyamine) was done by infrared spectroscopy which showed that alkaloids content of the irradiated seeds is altered by irradiation as the reference bands were not found with all doses used. In addition, seedlings grown from irradiated in vitro seeds exhibited remarkable morphological variations that varied based on the employed dose of gamma rays. These findings permitted the selection of the optimal irradiation dose (80 Gy) to induce mutations that are likely to prompt changes at genetic and metabolic level of the targeted alkaloids.

Xanthomonas Vesicatoria

Abstract A description is provided for Xanthomonas vesicatoria. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On tomato, Lycopersicon esculentum, and Chilli peppers, Capsicum frutescens; also on Lycopersicon pimpinelifolium, Datura stramonium, Hyoscyamus niger, H. aureus, Lycium chinense, L. halimifolium, Nicotiana rustica, Physalis minima, Solanum dulcamara, S. nigrum, S. rostratum, S. tuberosum, S. melongena. DISEASE: Bacterial scab or spot. The pathogen causes a superficial corky scab of the fruits with irregularly lobed margins and water-soaked halos, a leaf spot or blight and a canker of the stems and petioles. GEOGRAPHICAL DISTRIBUTION: U.S.A., Mexico, Canada, Jamaica, Puerto Rico, Bermuda, Brazil, Argentina, Hawaii, Australia, Japan, India, China. Israel, Italy, Hungary, Yugoslavia, Bulgaria, Rumania, Lithuania, U.S.S.R., Mozambique, South Africa, Southern Rhodesia. (CMI Map 269). TRANSMISSION: On seed and by wind driven rain. Leaf infection occurs through the stomata, fruit infection through wounds. Overwintering in the dead stalks of diseased tomato plants and also survival in rhizospheres of dead plants has been recorded by Peterson (Phytopathology 53: 765-767, 1963) as well as overwintering on wheat roots (25: 479). Fruit symptoms reported to be associated with punctures by Nezara viridula (37: 249).

Die Geschwindigkeit, mit der sich das Kartoffel-X-Virus im Blatt-Parenchym anfälliger Wirtspflanzen ausbreitet, wurde durch vergleichende Messungen an kreisförmigen Infektionsherden verschiedenen Alters ermittelt. Die gefundenen Werte betragen rund 0,3 mm im BIatt der Tabaksorte Samsun, 0,2 mm im Blatt der Tabaksorte Xanthia und 0,1 mm im Blatt von Datura Stramonium innerhalb 24 Stunden. Im nervenständigen Parenchym erfolgt die Ausbreitung erheblich schneller, wodurch die stärkeren Abweichungen von der Kreisform zustandekommen.Ferner wird gezeigt, daß die Vermehrung (Konzentrationszunahme) des X-Virus im geimpften Blatt unter bestimmten Voraussetzungen der Zunahme einer stetig wachsenden Kreisfläche gleichgesetzt werden kann und daß die Ausbreitung in den latenten Infektionsherden der Blätter von Atropa Belladonna mit derselben Geschwindigkeit erfolgt wie beim Samsun-Tabak.Die Frage nach dem Mechanismus der Virusausbreitung im Parenchym wird kurz gestreift, sie bedarf noch eingehender Erörterung und experimenteller Prüfung.
