  • Phytophthora Ramorum Sudden Oak Death Pathogen
    NAME OF SPECIES: Phytophthora ramorum Sudden Oak Death pathogen Synonyms: Common Name: Sudden Oak Death pathogen A. CURRENT STATUS AND DISTRIBUTION I. In Wisconsin? 1. YES NO X 2. Abundance: 3. Geographic Range: 4. Habitat Invaded: 5. Historical Status and Rate of Spread in Wisconsin: 6. Proportion of potential range occupied: II. Invasive in Similar Climate YES NO X Zones United States: In 14 coastal California Counties and in Curry County, Oregon. In nursery in Washington. Canada: Nursery in British Columbia. Europe: Germany, the Netherlands, the United Kingdom, Poland, Spain, France, Belgium, and Sweden. III. Invasive in Similar Habitat YES X NO Types IV. Habitat Affected 1. Habitat affected: this disease thrives in cool, wet climates including areas in coastal California within the fog belt or in low- lying forested areas along stream beds and other bodies of water. Oaks associated with understory species that are susceptible to foliar infections are at higher risk of becoming infected. 2. Host plants: Forty-five hosts are regulated for this disease. These hosts have been found naturally infected by P. ramorum and have had Koch’s postulates completed, reviewed and accepted. Approximately fifty-nine species are associated with Phytophthora ramorum. These species are found naturally infected; P. ramorum has been cultured or detected with PCR but Koch’s postulates have not been completed or documented and reviewed. Northern red oak (Quercus rubra) is considered an associated host. See end of document for complete list of plant hosts. National Risk Model and Map shows susceptible forest types in the mid-Atlantic region of the United States.

  • Tasmannia Lanceolata
    ASPECTS OF LEAF AND EXTRACT PRODUCTION from Tasmannia lanceolata by Chris Read, B. Agr.Sc. Tas. Submitted in fulfillment of the requirements for the Degree of Doctor of Philosophy University of Tasmania, Hobart December 1995 ' s~, ... ~~ \ ·'(11 a_C\14 \t\J. \I ' This thesis contains no material which has been accepted for the award of any other degree or diploma in any University, and to the best of my knowledge, contains no copy or paraphrase of material previously written or published by any other person except where due reference is given in the text. University of Tasmania HOBART March 1996 This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968 University of Tasmania HOBART March 1996 Abstract This thesis examines several aspects of the preparation, extraction and analysis of solvent soluble compounds from leaf material of Tasmannia lanceolata and reports a preliminary survey of extracts of some members of the natural population of the species in Tasmania. A major constituent of these extracts, polygodial, was shown to be stored within specialised idioblastic structures scattered throughout the mesophyll, and characterised by distinctive size and shape, and a thickened wall. The contents of these cells were sampled directly, analysed and compared with the composition of extracts derived from ground, dry whole leaf. This result was supported by spectroscopic analysis of undisturbed oil cells in whole leaf tissue. In a two year field trial, the progressive accumulation of a number of leaf extract constituents (linalool, cubebene, caryophyllene, germacrene D, bicyclogermacrene, cadina-1,4 - diene, aristolone and polygodial) during the growth flush was followed by a slow decline during the subsequent dormant season.

  • Diagnosis of Phytophthora Ramorum in Trees
    Diagnosis of PhytophthoraPhytophthora ramorumramorum in Trees by Dr. Kim D. Coder, Warnell School of Forest Resources, University of Georgia April, 2004 The organism shown to be responsible for SOD (sudden oak death) is Phytophthora ramorum, a fungus / yeast-like brown algae. This pathogen generates a number of symptoms in the trees infected. Of the trees and large shrubs shown to be infectable with this pathogen, some species have more serious stem and branch lesions like oaks, while other species have primarily leaf and twig lesions. In a single landscape, multiple hosts can keep the pathogen present for further attacks. This publication was prepared by reviewing approximately 35 research or disease announcement publications in Europe and North America. In addition, a number of factsheets and synthesized informa- tion guides were reviewed for continuity. This publication is designed for field diagnosis of SOD-like symptoms and related symptom sets on community trees. This publication should not be used in tree nursery situations, and is not a pathogen centered review. It is critical to seek pathological expertise and testing for confirming disease organism presence. A selected bibliography is available entitled “Sudden Oak Death – SOD: Bibliography of Important Literature.” (Coder, Kim D. 2004. University of Georgia, Warnell School of Forest Resources outreach publication SFR04-1. 2pp.). Names The tree syndrome or symptom set which characterizes attack by Phytophthora ramorum has common names of “ramorum dieback,” “ramorum blight,” “ramorum twig blight,”“ramorum leaf blight,” “ramorum stem canker,” “blood spot disease,” or “sudden oak death” (SOD). Phytophthora ramorum, and the less virulent Phytophthora nemorosa and Phytophthora pseudosyringae are all relatively new pathogen species recovered from trees which show ramorum blight symptoms.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese
