Abstract:

Datura stramonium (Solanaceae) is an annual weed found in most temperate and subtropical regions of the world. The taxonomic identity of this species is still under debate since Linnaeus first published the name. Early on, many varieties and forms were recognized. In Egypt, D. stramonium presents in two forms: the white-flowered ‘stramonium’ form and violet-flowered ‘tatula’ form. Some authors treated D. stramonium and D. tatula as two distinct species, while others included D. tatula within D. stramonium as either a variety or forma. The present study aimed to elucidate the taxonomic identity of both the white ‘stramonium’ and the violet ‘tatula’ forms based on morphological, palynological and cytogenetic studies extended to karyotyping. A taxonomic study of these forms was carried out using 75 morphological and pollen characters. Significant morphological differences were observed; the most important ones were flower and stem colour, in addition to flower and fruit dimensions. The anatomical examination of juvenile-fruit in acropetal transverse sections, revealed the gradual displacement of parietal placentation at the fruit base to axile at the fruit apex. Pollen of both forms showed no significant differences. Cytogenetic results revealed the presence of a diploid chromosome number (2n=2x=24) in both forms, with minor aneuploidy in the ‘tatula’ form. According to the karyotyping, notable differences were found between the two studied forms, including the centromeric index, total genomic length, and intrachromosomal asymmetry index. Morphological and cytogenetic data revealed that the two forms are different enough to be treated taxonomically as two distinct varieties, namely D. stramonium var. stramonium and D. stramonium var. tatula.

Abstract:

India has a great wealth of various naturally occurring plant drugs which have great potential pharmacological activities. Datura stramonium D. stramonium is one of the widely well known folklore medicinal herbs. Datura Familiy solanaceae , a genus of poisonous herbs, shrubs or small trees, is distributed throughout the tropical and warm temperate region of the world. The word 'Datura' is derived from the Arabic name 'Tatorah' or the Hindustani 'Dhatura'.This genus is represented by about 11 species Datura ceratocaula, D. innoxia, D. metel, D. quercifolia, D. stramonium, D. tatula, D. discolor, D. wrightii, D. alba, D. fastuosa, D. ferox of which D. innoxia, D. metel and D. stramonium are important drug plant whereas some are ornamenatals.

Abstract:

Flora of railways was investigated in the Jeseník District (Silesia, Czech Republic). Four red list species were found on the railway habitats: Papaver argemone, Saxifraga tridactylites, Urtica urens and Verbena officinalis. Papaver argemone and S. tridactylites have recently expanded along railways in many regions of the Czech Republic, which is also the case of the studied area. Senecio vernalis was confirmed after decades in the Jeseník District, while the finding of Datura stramonium var. tatula is so far the second case of naturalization of this taxon in the region of northern Moravia and Silesia. A further spreading of all studied taxa along railways should be monitored.

Abstract:

The influence of a varying Ca2+/K+ balance on alkaloid production and accumulation in Datura stramonium var. tatula L. Torr. (thorn-apple) was examined. Plants were grown in culture on two different mineral media, that varied only in the proportions of the two cations. In addition, plants were cultured under two different light regimes to investigate a possible interaction between different ecophysiological parameters. When plants were grown under a higher light energy regime, more alkaloids accumulated in the plants during a certain stage of development, but also a higher proportion was found in fruits and seeds. This was associated with a lower alkaloid content in leaves and stems. The observed effect of the Ca2+/K+ balance on alkaloid content in the leaves, was affected by the different light regimes. An interpretation, including the possible influence on glutamine content, is put forward.

Abstract:

AbstractThis paper presents the results of research on ephemerophytes of the alien portion of the flora of the Romensko-Poltavsky Geobotanical District (north-eastern Ukraine). It is a detailed study of this group of plants, conducted for the first time in the Ukraine. The checklist of alien vascular plants contains 345 species, of which 27 species are ephemerophytes (or 8%): Adonis aestivalis, A. annua, Papaver albiflorum, Urtica cannabina, Gypsophila perfoliata, Atriplex micrantha, Chenopodium × preissmannii, Ch. × thellungii, Rumex longifolius, Sisymbrium polymorphum, Euphorbia humifusa, Malus sylvestris, Onobrychis viciifolia, Astrodaucus orientalis, Datura tatula, Solanum schultesii, Lindernia procumbens, Melampyrum cristatum, Helianthus annuus, Petasites spurius, Xanthium ripicola × Xanthium albinum, Echinochloa tzvelevii, Panicum capillare, Panicum capillare L. subsp. barvipulvinatum, Phalaris canariensis, Setaria ×ambigua, Sorghum halepense. The basis of this work is original data of the author obtained during field studies, and a critical study of the literature, archival, cartographic materials and herbarium collections, and the use of classical methods of botanical classification. Complex research of this group of plants was conducted and as a result of these investigations the following characteristics were established: a predominance of kenophytes of Mediterranean origin in this group, species of arid areas, cosmopolitan species with a diffuse type of space structure, therophytes, herbaceous monocarpic plants, mesotrophes, heliophytes and xeromesophytes, with an insignificant degree of impact on native plant communities and with a limited distribution within the study region. The combination of these results indicates that ephemerophytes comprise a temporary, unstable component of the flora of this region of the Ukraine. The paper provides maps of the distribution of these 27 species.

Abstract:

Potato virus A (PVA; genus Potyvirus, family Potyviridae) occurs wherever potatoes are grown and may reduce tuber yields as much as 40%. Its host range consists of six experimental hosts (Lycopersicon pimpinellifolium (Jusl.) P. Mill., Nicandra physalodes (L.) Gaertn., Nicotiana tabacum L., Solanum demissum Lindl., S. demissum × S. tuberosum, and Nicotiana debneyi Domin.) and two natural hosts (S. tuberosum L. and S. betaceae (Cav.) Sendt.) (1). N. physalodes and Nicotiana tabacum sometimes grow in nature in the eastern and southern United States (2) but have not been reported to be PVA sources in nature. PVA is known to survive winter in temperate climates only in tubers used for potato propagation and potato volunteers. We detected PVA in all six Black Nightshade (S. nigrum L.) and all six Hairy Nightshade (S. sarrachoides Sendt.) weeds expressing mild mosaic symptoms and growing in PVA-infected potato fields near Prosser, WA in September of 2002. PVA was not detected in any of the 24 Cutleaf Nightshade (S. trifolium) plants selected from the same fields. The virus was detected using double antibody sandwich enzyme-linked immunosorbent assay with a test kit obtained from Agdia, Inc. (Elkhart, IN) and by reverse transcription-polymerase chain reaction using primers designated 3 (gta-ctg-aac-tgg-aaa-agt-act) and 4 (ccc-tga-cag-ttg-aaa-cat-aag) (3). One positive control for these assays was a PVA virus isolate from the “Shultz Collection” provided by Robert Goth (USDA, ARS, Beltsville, MD) in 1986. The Agdia, Inc. test kit also provided a positive control. We also transmitted PVA from one of the Black Nightshade and one of the Hairy Nightshade weeds to greenhouse-produced Nicotiana megalosiphon Van Heurck & Mull. Agr., Nicotiana tabacum cv. Samsum NN, S. tuberosum cv. Russet Burbank, S. sarrachoides, and S. nigrum plants by Myzus persicae Sulzer in a stylet-borne manner. The virus was transmitted from the greenhouse test plants back to S. sarrachoides and S. nigrum plants where it produced mild mosaic symptoms identical to virus from the original sources. PVA was not transmitted from weedy sources to Datura tatula L., Physalis floridana Rydb., or S. trifolium. M. persicae readily colonized S. sarrachoides, S. nigrum, and S. trifolium in the field and greenhouse. Since black and hairy nightshade are frequently found in potato fields (4) and our findings show these weeds to be hosts of PVA, their role in the epidemiology of this disease should be more fully evaluated.

Abstract:

IntroductionDatura, long considered an medicinal plant, represents a prospective source for discovering novel drugs for modern medicine. The Egyptian flora encompasses six Datura genotypes, including D. innoxia, D. ferox, D. metel and three forms of D. stramonium (stramonium, tatula and inermis). However, the taxonomic status of Datura genus remains controversial.MethodsOur study aims to clarify the phylogenetic relationships among Egyptian Datura via contemporary molecular taxonomy techniques, including ISSR, SCoT, CDDP, as well as cytogenetics assessment, and chemical taxonomy, using total- and tropane-alkaloid and UV spectroscopic pattern.ResultsBased on our results, the three forms of D. stramonium (stramonium, tatula and inermis) are closely related taxa, although there were some significant differences, suggesting the need to upgrade inermis to level of subspecies (Datura stramonium subsp. Inermis). The GC-MS results identified 31 tropane alkaloids. Out of which, seven were described in a qualitative manner in genus Datura, which enhances these genotypes’ medical and economic value. Expression level of the genes PMT, TR1, TR2, H6H, HDH and AT4 influenced the tropane alkaloids accumulation within the genotypes examined.DiscussionTo date, this is the first study to identify the evolutionary relationship of the genus Datura combining molecular and chemical taxonomy, and to quantify the TAs and the genes involved in their biosynthesis among Datura genotypes.ConclusionThis study is significant since drug development strategies and enhanced therapeutic usage of Datura heavily depend on comprehensive knowledge of the species and subspecies’ molecular and phytochemical variability.

Abstract:

Summary Alkaloids and alkaloid-producing plants have the potential to reduce crop damage by plant-parasitic nematodes. In a series of in vitro experiments, the nematicidal activity of the tropane alkaloids, hyoscyamine and scopolamine, and a mixture of both on the root-knot nematode, Meloidogyne incognita, was tested. Solutions of 16 mg of compound per ml of solvent were used in concentrations of 80-1280 μg ml−1 of water. Inactivity of second-stage juveniles of M. incognita increased with increasing concentration and exposure time. Lethal concentrations (LC50) after 120 min of exposure ranged from 182.4 μg ml−1 for scopolamine to 318.4 μg ml−1 for hyoscyamine and 332.8 μg ml−1 for the combination of both alkaloids. Similarly, the same concentrations of scopolamine inhibited hatching of M. incognita to a greater extent than hyoscyamine. In a glasshouse experiment, M. incognita was not able to penetrate the roots, induce galls and reproduce on Datura stramonium, D. innoxia and D. tatula. Results indicate that the tropane alkaloids hyoscyamine and scopolamine contained in Datura plants express a strong nematicidal activity against M. incognita and could possibly be used for an alternative and sustainable nematode management.
