  • Genetic Diversity and Phylogeny in Hystrix (Poaceae, Triticeae) and Related Genera Inferred from Giemsa C-Banded Karyotypes
    Genetics and Molecular Biology, 32, 3, 521-527 (2009) Copyright © 2009, Sociedade Brasileira de Genética. Printed in Brazil www.sbg.org.br Research Article Genetic diversity and phylogeny in Hystrix (Poaceae, Triticeae) and related genera inferred from Giemsa C-banded karyotypes Hai-Qin Zhang1,2, Rui-Wu Yang3, Li Zhang3, Chun-Bang Ding3, Jian Zeng1 and Yong-Hong Zhou1,2 1Triticeae Research Institute, Sichuan Agricultural University, Sichuan, China. 2Key Laboratory of Crop Genetic Resources and Improvement, Ministry of Education, Sichuan Agricultural University, Sichuan, China. 3College of Biology and Science, Sichuan Agricultural University, Sichuan, China. Abstract The phylogenetic relationships of 15 taxa from Hystrix and the related genera Leymus (NsXm), Elymus (StH), Pseudoroegneria (St), Hordeum (H), Psathyrostachys (Ns), and Thinopyrum (E) were examined by using the Giemsa C-banded karyotype. The Hy. patula C-banding pattern was similar to those of Elymus species, whereas C-banding patterns of the other Hystrix species were similar to those of Leymus species. The results suggest high genetic diversity within Hystrix, and support treating Hy. patula as E. hystrix L., and transferring Hy. coreana, Hy. duthiei ssp. duthiei and Hy. duthiei ssp. longearistata to the genus Leymus. On comparing C-banding patterns of Elymus species with their diploid ancestors (Pseudoroegneria and Hordeum), there are indications that certain chro- mosomal re-arrangements had previously occurred in the St and H genomes. Furthermore, a comparison of the C-banding patterns of the Hystrix and Leymus species with the potential diploid progenitors (Psathyrostachys and Thinopyrum) suggests that Hy. coreana and some Leymus species are closely related to the Ns genome of Psathyrostachys, whereas Hy.

    AJCS 5(12):1501-1507 (2011) ISSN:1835-2707 Taxonomic revision of the genus Psathyrostachys Nevski (Poaceae: Triticeae) in Turkey Evren Cabi 1*, Musa Do ğan 2, Ersin Karabacak 3 1Atatürk University, Faculty of Science, Department of Biology, 25240, Erzurum, TURKEY 2Middle East Technical University, Faculty of Arts and Sciences, Department of Biological Sciences, 06531, Ankara, TURKEY 3Çanakkale Onsekiz Mart University, Faculty of Arts and Sciences, Department of Biology, 17020, Çanakkale, TURKEY *Corresponding author: [email protected] Abstract In this study, the genus Psathyrostachys Nevski is revised in Turkey. Furthermore multivariate analysis have been carried out in order to understand the delimitation of the taxa of Psathyrostachys. For this reason, 20 quantitative, qualitative and multi-state morphological characters were scored for the accessions representing 10 populations of the genus. The data were subjected to numerical taxonomic analysis. The results showed that the genus is represented by 3 species one of which is new species and the other one is a new record for Turkey. An account of 3 species and 4 subspecies recognized in the genus is given including the genus description, a key for the species as well as the subspecies, species descriptions, flowering times, habitats, altitudes, type citations, distributions, phytogeography and their conservation status. However, three new taxa, namely P. narmanica sp. nov ., P. fragilis subsp. artvinense subsp. nov. and P. daghestanica subsp erzurumica subsp. nov. are described and illustrated for the first time. Keywords: Poaceae, Psathyrostachys , revision, Turkey. Introduction The genus Psathyrostachys Nevski (Poaceae; Triticeae) is a anatomical studies have also been done on certain grass small, well-defined, perennial genus comprising only eight genera (Do ğan, 1988, 1991, 1992, 1997; Cabi and Do ğan, species (Baden 1991).

  • 'Mankota' Russian Wildrye Release Brochure
    ‘Mankota’ Russian Wildrye Psathyrostachys juncea A Conservation Plant Release by USDA NRCS Plant Materials Center, Bismarck, North Dakota Source Mankota traces to plants selected from a source population of 29 different cultivars, experimental strains, and plant introductions. Selected plants were tested at the Northern Great Plains Research Laboratory, Mandan, ND, for seedling emergence from a 2-inch planting depth, stand establishment, resistance to leafspot diseases, lodging, and forage and seed yields. Uses Russian wildrye is better suited to grazing than to hay production. Russian wildrye is usually sown alone because it develops an extensive root system that provides high plant competition to most other forage species. Once 'Mankota' Russian wildrye Psathyrostachys juncea established, Russian wildrye is tolerant of heavy fall (Fisch.)

  • New Perspectives on Medicinal Properties and Uses of Iris Sp
    Hop and Medicinal Plants, Year XXIV, No. 1-2, 2016 ISSN 2360 – 0179 print, ISSN 2360 – 0187 electronic NEW PERSPECTIVES ON MEDICINAL PROPERTIES AND USES OF IRIS SP. CRIŞAN Ioana, Maria CANTOR* Faculty of Horticulture, University of Agricultural Sciences and Veterinary Medicine, Manastur Street 3-5, 400372 Cluj-Napoca, Romania *corresponding author: [email protected] Abstract. Rhizomes from various Iris species have been used in traditional medicine to treat a variety of ailments since ancient times and many constituents isolated from different Iris species demonstrated potent biological activities in recent studies. All research findings besides the increasing demand for natural ingredients in cosmetics and market demand from industries like alcoholic beverages, cuisine and perfumery indicate a promising future for cultivation of irises for rhizomes, various extracts but most importantly for high quality orris butter. Romania is situated in a transitional continental climate with suitable conditions for hardy iris species and thus with good prospects for successful cultivation of Iris germanica, Iris florentina and Iris pallida in conditions of economic efficiency. Key words: Iris, medicinal plant, orris butter, rhizomes Introduction The common word “iris” that gave the name of the genus, originates from Greek designating “rainbow” presumably due to the wide variety of colors that these flowers can have (Cumo, 2013). The genus reunites about 300 species (Wang et al., 2010) with rhizomes or bulbs (Cantor, 2016). In Romanian wild flora can be met both naturalized and native species, some enjoying special protection, like Iris aphylla ssp. hungarica (Marinescu and Alexiu, 2013) that can be seen on the hills nearby Cluj-Napoca (Fig.

    United States Department of Agriculture Rangelands of Central Asia: Forest Service Rocky Mountain Research Station Proceedings of the Conference Proceedings RMRS-P-39 on Transformations, Issues, and June 2006 Future Challenges Bedunah, Donald J., McArthur, E. Durant, and Fernandez-Gimenez, Maria, comps. 2006. Rangelands of Cen- tral Asia: Proceedings of the Conference on Transformations, Issues, and Future Challenges. 2004 January 27; Salt Lake City, UT. Proceeding RMRS-P-39. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 127 p. Abstract ________________________________________ The 11 papers in this document address issues and needs in the development and stewardship of Central Asia rangelands, and identify directions for future work. With its vast rangelands and numerous pastoral populations, Central Asia is a region of increasing importance to rangeland scientists, managers, and pastoral development specialists. Five of the papers address rangeland issues in Mongolia, three papers specifically address studies in China, two papers address Kazakhstan, and one paper addresses the use of satellite images for natural resource planning across Central Asia. These papers comprise the proceedings from a general technical conference at the 2004 Annual Meeting of the Society for Range Management, held at Salt Lake City, Utah, January 24-30, 2004. As the 2004 SRM Conference theme was “Rangelands in Transition,” these papers focus on an area of the world that has experienced dramatic socio-economic changes in 20th Century associated with adoption of communism and command economies and the subsequent collapse of the command economies and the recent transition to a free market economies. The changes in land use and land tenure policies that accompanied these shifts in socio economic regimes have had dramatic impacts on the region’s rangelands and the people who use them.

  • Secondary Metabolites of the Choosen Genus Iris Species
    ACTA UNIVERSITATIS AGRICULTURAE ET SILVICULTURAE MENDELIANAE BRUNENSIS Volume LX 32 Number 8, 2012 SECONDARY METABOLITES OF THE CHOOSEN GENUS IRIS SPECIES P. Kaššák Received: September 13,2012 Abstract KAŠŠÁK, P.: Secondary metabolites of the choosen genus iris species. Acta univ. agric. et silvic. Mendel. Brun., 2012, LX, No. 8, pp. 269–280 Genus Iris contains more than 260 species which are mostly distributed across the North Hemisphere. Irises are mainly used as the ornamental plants, due to their colourful fl owers, or in the perfume industry, due to their violet like fragrance, but lot of iris species were also used in many part of the worlds as medicinal plants for healing of a wide spectre of diseases. Nowadays the botanical and biochemical research bring new knowledge about chemical compounds in roots, leaves and fl owers of the iris species, about their chemical content and possible medicinal usage. Due to this researches are Irises plants rich in content of the secondary metabolites. The most common secondary metabolites are fl avonoids and isofl avonoids. The second most common group of secondary metabolites are fl avones, quinones and xanthones. This review brings together results of the iris research in last few decades, putting together the information about the secondary metabolites research and chemical content of iris plants. Some clinical studies show positive results in usage of the chemical compounds obtained from various iris species in the treatment of cancer, or against the bacterial and viral infections. genus iris, secondary metabolites, fl avonoids, isofl avonoids, fl avones, medicinal plants, chemical compounds The genus Iris L.
