  • Monocyclic Components for Evaluating Disease Resistance to Cercospora Arachidicola and Cercosporidium Personatum in Peanut
    Monocyclic Components for Evaluating Disease Resistance to Cercospora arachidicola and Cercosporidium personatum in Peanut by Limin Gong A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 6, 2016 Keywords: monocyclic components, disease resistance Copyright 2016 by Limin Gong Approved by Kira L. Bowen, Chair, Professor of Entomology and Plant Pathology Charles Y. Chen, Associate Professor of Crop, Soil and Environmental Sciences John F. Murphy, Professor of Entomology and Plant Pathology Jeffrey J. Coleman, Assisstant Professor of Entomology and Plant Pathology ABSTRACT Cultivated peanut (Arachis hypogaea L.) is an economically important crop that is produced in the United States and throughout the world. However, there are two major fungal pathogens of cultivated peanuts, and they each contribute to substantial yield losses of 50% or greater. The pathogens of these diseases are Cercospora arachidicola which causes early leaf spot (ELS), and Cercosporidium personatum which causes late leaf spot (LLS). While fungicide treatments are fairly effective for leaf spot management, disease resistance is still the best strategy. Therefore, it is important to evaluate and compare different genotypes for their disease resistance levels. The overall goal of this study was to determine resistance levels of different peanut genotypes to ELS and LLS. The peanut genotypes (Chit P7, C1001, Exp27-1516, Flavor Runner 458, PI 268868, and GA-12Y) used in this study include two genetically modified lines (Chit P7 and C1001) that over-expresses a chitinase gene. This overall goal was addressed with three specific objectives: 1) determine suitable conditions for pathogen culture and spore production in vitro; 2) determine suitable conditions for establishing infection in the greenhouse; 3) compare ELS and LLS disease reactions of young plants to those of older plants.

Canada V5A IS6 The Canadian Entomologist 132: 243 - 245 (2000) An isolated stand of western white pine, Pinus monticola Dougl. ex D. Don, on Texada Island (49”4O’N, 124”1O’W), British Columbia, is extremely valuable as a seed-production area for progeny resistant to white pine blister rust, Cronartium ribicola J.C. Fisch. (Cronartiaceae). During the past 5 years, cone beetles, Conophthorus ponderosae Hopkins (= C. monticolae), have severely limited crops of western white pine seed from the stand. Standard management options for cone beetles in seed orchards are not possible on Texada Island. A control program in wild stands such as the one on Texada Island requires alternate tactics such as a semiochemical-based trapping program. Females of the related species, Conophthorus coniperda (Schwarz) and Conophthorus resinosae Hopkins, produce (+)-pityol, (2R,5S)-2-( 1 -hydroxyl- 1 -methylethyl)-5-methyl-tetrahydrofuran, a sex pheromone that attracts males of both species (Birgersson et al.

Plant Pathology & Quarantine 6(1), 43–46, Doi 10.5943/ppq/6/1/6 Abstract In September 2012, leaves of Solidago canadensis with typical symptoms of rust were collected in the Botanical Garden of Yashvantrao Chavan Institute of Science, Satara (MS, India). The rust was identified as Coleosporium asterum. This rust is recorded on S. canadensis in India for the first time. Key words – Asteraceae – Coleosporiaceae – Coleosporium asterum – Solidago canadensis. Introduction Solidago canadensis L. (Asteraceae) (cf. The Plant List, 2014) (Fig. 1A), commonly called Canadian goldenrod, is native to North America (Hegi 1979). It often occurs as a weed in abandoned fields and roadsides, grasslands, forest edges and human-influenced habitats in urban areas and settlements (Walck et al. 1999). It is also cultivated as an ornamental in botanical gardens and home gardens in various parts of the world. The plant is exotic to India and was introduced for its ornamental value. The inflorescence of the plant forms a broad pyramidal panicle with a central axis and recurving branches giving it a gorgeous look. Its golden yellow attractive inflorescence is largely used in bouquets.

  • Fungal Survey for Biocontrol Agents of Ipomoea Carnea from Brazil
    Fungal survey for biocontrol agents of Ipomoea carnea from Brazil D.J. Soares and R.W. Barreto Summary Ipomoea carnea Jacq., also known as morning glory, is native of tropical America, and its purported centre of origin is the Paraguay Basin. This plant is feared by ranchers because of its well-documented toxicity to cattle. Because of its showy flowers, it became a popular ornamental in Brazil and was introduced into others countries, becoming an aggressive wetland ecosystem invader. Little is known about its mycobiota in Brazil which may include fungal pathogens that could be used in classical bio- control programmes. Coleosporium ipomoeae (Schwein.) Burril and Puccinia puta H.S. Jacks. and Holw. ex F. Kern, Thurst. and Whetzel are the only fungi recorded in the literature attacking this plant in Brazil. An intensive search for specialized, coevolved fungal pathogens of I. carnea was initiated in 2003 in Brazil. Twenty-one fungal species were collected. Among these were the two previously known rusts, C. ipomoeae and P. puta, and Aecidium sp., Albugo sp., an unidentified ascomycete, Mycosphaerella sp., five coelomycetes Colletotrichum( sp., Phoma sp. Phomopsis sp., and two Phyl- losticta spp.) and ten hyphomycetes (Alternaria sp., Cercospora sp., Cladosporium sp., Curvularia sp., Dactylaria-like, Fusarium-like, Nigrospora sp. Passalora sp. and two Pseudocercospora spp.). Observations of the damage caused by such fungal diseases in the field indicate that the fungi with the best potential as biological agents are C. ipomoeae, P. puta, Albugo sp., the Phyllostica sp. that colonizes stems, and Phomopsis sp. Keywords: aquatic weeds, biological control, coevolved pathogens, Ipomoea fistulosa, Ipomoea carnea subsp.

  • Oxalis Violacea L. Violet Wood-Sorrel
    New England Plant Conservation Program Oxalis violacea L. Violet Wood-Sorrel Conservation and Research Plan for New England Prepared by: Thomas Mione Professor Central Connecticut State University For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, December 2002 1 SUMMARY Violet Wood-Sorrel (Oxalis violacea L., Oxalidaceae) is a low-growing herbaceous, self-incompatible perennial that produces violet flowers in May, June and again in September. Reproduction is both sexual (with pollination mostly by bees), and asexual (by way of runners). The species is widely distributed in the United States but is rare in New England. Oxalis violacea is an obligate outcrosser: the species is distylous, meaning that there are two flower morphs (pin and thrum), with a given plant producing one morph, not both. Pin flowers are more common than thrum flowers. In New England, the habitat varies from dry to moist, and for populations to remain vigorous forest canopies must remain partially open. Succession, the growth of plants leading to shading, is a factor contributing to decline of O. violacea in New England, as are invasive species and habitat fragmentation. Fire benefits this species, in part by removing competitors. Human consumption of the leaves has been reported. Oxalis violacea has a Global Status Rank of G5, indicating that it is demonstrably widespread, abundant and secure. In Massachusetts, it is ranked as Threatened; five occurrences are current (in four towns among three counties) and 10 are historic. In Connecticut, it is listed as a species of Special Concern; 10 occurrences are current (in ten towns among six counties) and 19 are historic.

  • 9B Taxonomy to Genus
    Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known. (Explanation paraphrased from "Dictionary of the Fungi, 9th Edition.") Principal authority for this taxonomy is the Dictionary of the Fungi and its online database, www.indexfungorum.org. For lichens, see Lecanoromycetes on p. 3. Basidiomycota Aegerita Poria Macrolepiota Grandinia Poronidulus Melanophyllum Agaricomycetes Hyphoderma Postia Amanitaceae Cantharellales Meripilaceae Pycnoporellus Amanita Cantharellaceae Abortiporus Skeletocutis Bolbitiaceae Cantharellus Antrodia Trichaptum Agrocybe Craterellus Grifola Tyromyces Bolbitius Clavulinaceae Meripilus Sistotremataceae Conocybe Clavulina Physisporinus Trechispora Hebeloma Hydnaceae Meruliaceae Sparassidaceae Panaeolina Hydnum Climacodon Sparassis Clavariaceae Polyporales Gloeoporus Steccherinaceae Clavaria Albatrellaceae Hyphodermopsis Antrodiella

Abstract Mesosphaerum suaveolens L. (Kuntze) is a perennial, erect, annual and aromatic herb that may grow up to height of 2m. Mesosphaerum suvaveolens methanolic extract fractionization was carried out in chloroform. From chloroform fraction triterpenoid was isolated by column chromatography. Triterpenoid identification did via chemical test, physical properties, TLC pattern. Then, the confirmation of chemical constituents was carried out by instrumental techniques as; UV, IR, MS and NMR. The tetracyclic triterpenoid stigmasterol structure interpreted at lastly. The ethanobotanical survey claim the valuable plant used for treating inflammation and rheumatoid arthritis (RA), No doubt, the further investigation must be needed for determining different pharmacological activity and medicinal use of Mesosphaerum suaveolens. But, at this level the present study claim that the stated activity is because of stigmasterol, because in inflammation and RA the steroids and triterpenoid play a vital role.
