  • 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.

Manitoba Conservation Data Centre Surveys and Stewardship Activities, 2014 By Colin Murray Carla Church Manitoba Conservation Data Centre Wildlife Branch Manitoba Conservation and Water Stewardship Winnipeg, Manitoba Executive Summary In 2014, the Manitoba Conservation Data Center (MBCDC) added 538 new occurrences to its biodiversity geospatial database. This represents thousands of species at risk (SAR) observations for 260 plant, 92 animal and 19 invertebrate species. Observations were gathered by MBCDC staff and also submitted to the MBCDC by individuals and other organisations. This information will further enhance our understanding of biodiversity in Manitoba and guide research, development, and educational efforts. This year MBCDC field surveys targeted 21 species which are listed under the federal Species at Risk Act, assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), and listed under Manitoba’s Endangered Species and Ecosystems Act, and especially occurring in the mixed-grass prairie and sand hill areas of southwestern Manitoba.

  • Plant Species on Salt-Affected Soil at Cheyenne Bottoms, Kansas
    TRANSACTIONS OF THE KANSAS Vol. 109, no. 3/4 ACADEMY OF SCIENCE p. 207-213 (2006) Plant species on salt-affected soil at Cheyenne Bottoms, Kansas TODD A. ASCHENBACH1 AND KELLY KINDSCHER2 1. Department of Ecology and Evolutionary Biology, University of Kansas, Lawrence, Kansas 66045-2106 ([email protected]) 2. Kansas Biological Survey, University of Kansas, Lawrence, Kansas 66047-3729 ([email protected]). Soil salinity and vegetative cover were investigated at Cheyenne Bottoms Preserve, Kansas in an effort to identify and document the plant species present on naturally occurring salt- and sodium-affected soil. Soil salinity (as indicated by electrical conductivity, ECe) and sodium adsorption ratio (SAR) were measured from nine soil samples collected to a depth of 20 cm in June 1998. Vegetative cover was visually estimated in June and September 1998. A total of 20 plant species were encountered at five soil sampling locations on soils classified as saline, saline-sodic, or sodic. Dominant species observed include Agropyron smithii, Distichlis spicata, Euphorbia geyeri, Poa arida, and Sporobolus airoides. While most species encountered during this study exhibited greater vegetative cover on non-saline soils, all of the dominant species, except A. smithii, exhibited greater cover on salt-affected soil compared to non- saline soil. Comparable salinity levels and species found in areas that have been degraded through oil and gas production activities suggest that the dominant species observed in this study deserve further attention as potential candidates for the restoration of salt-affected areas. Key Words: brine contamination, Cheyenne Bottoms, restoration, saline-sodic, salinity, salt tolerance. INTRODUCTION osmotic stress, ion toxicity or decreased absorption of essential nutrients (Läuchli and Salt-affected soils are commonly found in arid Epstein 1990).

Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 44 p. Abstract Administered by the USDA Forest Service, the Kiowa and Rita Blanca National Grasslands occupy 230,000 acres of public land extending from northeastern New Mexico into the panhandles of Oklahoma and Texas. A mosaic of topographic features including canyons, plateaus, rolling grasslands and outcrops supports a diverse flora. Eight hundred twenty six (826) species of vascular plant species representing 81 plant families are known to occur on or near these public lands. This report includes a history of the area; ethnobotanical information; an introductory overview of the area including its climate, geology, vegetation, habitats, fauna, and ecological history; and a plant survey and information about the rare, poisonous, and exotic species from the area. A vascular plant checklist of 816 vascular plant taxa in the appendix includes scientific and common names, habitat types, and general distribution data for each species. This list is based on extensive plant collections and available herbarium collections. Authors Donald L.

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.) Nevski (Mandan R 1808, PI-556988) was grazing, and the basal leaves provide high quality forage. released cooperatively in March 1991 by the USDA Fall regrowth is rapid if soil water is adequate.
