This plant has been used in traditional medicine in different cultures as a hallucinatory, analgesic, aphrodisiac, nematicide, sleep inducer, and muscle relaxant, as well as a treatment for rheumatism, asthma, and inflammation. The flowers, fruits, stems, and roots of the plant are used, and different chemical compounds have been identified, such as alkaloids, volatile compounds (mainly terpenes), coumarins, flavonoids, steroids, and hydrocarbons. The concentration of the different compounds varies according to the biotic and abiotic factors to which the plant is exposed.

    "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."

    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

The results support the splitting of Datura and Published: October 2018 Brugmansia into two distinct genera (BS 100 & 91). D. ceratocaula earlier considered as the connecting link between the two genera, is nested within the Datura clade (BS 57) as a distinct species. Although the three conventional sections of Datura viz. Dutra, Ceratocaulis & Datura (Stramonium) stand well supported (BS 100, 100 & 83), D. kymatocarpa, D. leichhardtii and D. pruinosa appear shifted from Section Dutra to Section Datura, corroborating earlier observations. D. discolor remains nested within the Section Dutra, refuting earlier suggestions as intermediary or ancestral role. But the divergence of D. discolor from the remaining taxa within the section Dutra as a clearly supported subclade (BS 100) may be suggestive of the subdivision of Section Dutra into two subsections. This subdivision of section Dutra however remains to be appraised using cladistical studies incorporating both molecular and morphological data.

The most important family was Asteraceae with 22 species, followed by Fabaceae s.l. with 11, and Solanaceae with eight. More than 90 general medicinal indications were recorded to treat a wide range of illnesses and ailments. The highest number of species and applications were reported for digestive system disorders (stomach ailments and liver problems), musculoskeletal body system (rheumatism and the complex of contusions, luxations, sprains, and swellings), kidney and other urological problems, and gynecological disorders. Some medicinal species had magic connotations, e.g. for cleaning and protection against ailments, to bring good luck, or for Andean offerings to Pachamama, ‘Mother Nature’. In some indications, the separation between medicinal and magic plants was very narrow. Most remedies were prepared from a single species, however some applications were always prepared with a mixture of plants, e.g.

Tropane and Granatane Alkaloid Biosynthesis: A Systematic Analysis Abstract The tropane and granatane alkaloids belong to the larger pyrroline and piperidine classes of plant alkaloids, respectively. Their core structures share common moieties and their scattered distribution among angiosperms suggest that their biosynthesis may share common ancestry in some orders, while they may be independently derived in others. Tropane and granatane alkaloid diversity arises from the myriad modifications occurring ot their core ring structures. Throughout much of human history, humans have cultivated tropane- and granatane-producing plants for their medicinal properties. This manuscript will discuss the diversity of their biological and ecological roles as well as what is known about the structural genes and enzymes responsible for their biosynthesis.

Bot. 29 (2): 225-230 Abstract: Downy thorn-apple Datura innoxia Mill is native in southwest U.S.A. and Mexico. It has been recorded as a new alien species to the vascular flora ofBosnia and Herzegovina. In Bosnia and Herzegovina, D. innoxia is reported from two localities in the city of Mostar where the species has escaped cultivation and established small populations in surrounding ruderal habitats including waste land. The species is toxic to animals and humans. The paper presents a short morphological characteristic and photographs as well as the distribution of the species in the Bosnia and Herzegovina. Keywords: alien plants, Bosnia and Herzegovina, Datura, distribution, garden escape, morphology. Introduction The genus Datura L. belongs to the tribe Datureae G. Don, of Solanaceae. There are about 10 species which occur naturally in south-western USA and Mexico, and parts of Central America (Dupin & Smith 2018). Within the genus Datura, only six species have been recorded as escapees in Europe of which four have been reported in the Balkans: Datura ferox L., Datura innoxia Mill., Datura metel L. and Datura stramonium L.

A phylogeny of Solanaceae is presented based on the chloroplast DNA regions ndhF and trnLF. With 89 genera and 190 species included, this represents a nearly comprehensive genus-level sampling and provides a framework phylogeny for the entire family that helps integrate many previously-published phylogenetic studies within So- lanaceae. The four genera comprising the family Goetzeaceae and the monotypic families Duckeodendraceae, Nolanaceae, and Sclerophylaceae, often recognized in traditional classifications, are shown to be included in Solanaceae. The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive “x = 12” clade, which includes Nicotiana and the Australian tribe Anthocercideae. These results also provide greater resolution among lineages within Solanoideae, confirming Jaltomata as sister to Solanum and identifying a clade comprised primarily of tribes Capsiceae (Capsicum and Lycianthes) and Physaleae.

    (Trnf) Pseudogenes Defines a Distinctive Clade in Solanaceae Péter Poczai* and Jaakko Hyvönen

    Poczai and Hyvönen SpringerPlus 2013, 2:459 http://www.springerplus.com/content/2/1/459 a SpringerOpen Journal SHORT REPORT Open Access Discovery of novel plastid phenylalanine (trnF) pseudogenes defines a distinctive clade in Solanaceae Péter Poczai* and Jaakko Hyvönen Abstract Background: The plastome of embryophytes is known for its high degree of conservation in size, structure, gene content and linear order of genes. The duplication of entire tRNA genes or their arrangement in a tandem array composed by multiple pseudogene copies is extremely rare in the plastome. Pseudogene repeats of the trnF gene have rarely been described from the chloroplast genome of angiosperms. Findings: We report the discovery of duplicated copies of the original phenylalanine (trnFGAA) gene in Solanaceae that are specific to a larger clade within the Solanoideae subfamily. The pseudogene copies are composed of several highly structured motifs that are partial residues or entire parts of the anticodon, T- and D-domains of the original trnF gene. Conclusions: The Pseudosolanoid clade consists of 29 genera and includes many economically important plants such as potato, tomato, eggplant and pepper.
