OCCURRENCE of STONE FRUIT VIRUSES in PLUM ORCHARDS in LATVIA Alina Gospodaryk*,**, Inga Moroèko-Bièevska*, Neda Pûpola*, and Anna Kâle*
PROCEEDINGS OF THE LATVIAN ACADEMY OF SCIENCES. Section B, Vol. 67 (2013), No. 2 (683), pp. 116–123. DOI: 10.2478/prolas-2013-0018 OCCURRENCE OF STONE FRUIT VIRUSES IN PLUM ORCHARDS IN LATVIA Alina Gospodaryk*,**, Inga Moroèko-Bièevska*, Neda Pûpola*, and Anna Kâle* * Latvia State Institute of Fruit-Growing, Graudu iela 1, Dobele LV-3701, LATVIA [email protected] ** Educational and Scientific Centre „Institute of Biology”, Taras Shevchenko National University of Kyiv, 64 Volodymyrska Str., Kiev 01033, UKRAINE Communicated by Edîte Kaufmane To evaluate the occurrence of nine viruses infecting Prunus a large-scale survey and sampling in Latvian plum orchards was carried out. Occurrence of Apple mosaic virus (ApMV), Prune dwarf virus (PDV), Prunus necrotic ringspot virus (PNRSV), Apple chlorotic leaf spot virus (ACLSV), and Plum pox virus (PPV) was investigated by RT-PCR and DAS ELISA detection methods. The de- tection rates of both methods were compared. Screening of occurrence of Strawberry latent ringspot virus (SLRSV), Arabis mosaic virus (ArMV), Tomato ringspot virus (ToRSV) and Petunia asteroid mosaic virus (PeAMV) was performed by DAS-ELISA. In total, 38% of the tested trees by RT-PCR were infected at least with one of the analysed viruses. Among those 30.7% were in- fected with PNRSV and 16.4% with PDV, while ApMV, ACLSV and PPV were detected in few samples. The most widespread mixed infection was the combination of PDV+PNRSV. Observed symptoms characteristic for PPV were confirmed with RT-PCR and D strain was detected. Com- parative analyses showed that detection rates by RT-PCR and DAS ELISA in plums depended on the particular virus tested. -

A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Vinca major L. Big periwinkle Family: Apocynaceae Range: Primarily California, but also Oregon, Washington, Idaho, Utah, Arizona, New Mexico and much of the southern and eastern United States. Habitat: Riparian corridors, moist woodlands, forest margins, coastal habitats, and disturbed sites such as roadsides and old homesteads. Grows best under moist, shady conditions on sandy to medium loam soil, with acidic to neutral pH. Can also tolerate drought, full sun, heavy clay and slightly alkaline soils. Foliage is susceptible to frost damage. Origin: Native to central Europe and the Mediterranean region. Introduced to the United States in the 1700s as an ornamental and for medicinal uses. Impacts: Under favorable conditions, plants spread invasively and can develop a dense ground cover that outcompetes other vegetation in natural areas. Big periwinkle is becoming a dominant woodland understory in many areas of California. Infestations around old homesteads have been present for many years and serve as nurseries for further spread. Some plants in the dogbane (Apocynaceae) family are extremely toxic, although poisoning due to the ingestion of big periwinkle is poorly documented. -

Landscaping Near Black Walnut Trees
Selecting juglone-tolerant plants Landscaping Near Black Walnut Trees Black walnut trees (Juglans nigra) can be very attractive in the home landscape when grown as shade trees, reaching a potential height of 100 feet. The walnuts they produce are a food source for squirrels, other wildlife and people as well. However, whether a black walnut tree already exists on your property or you are considering planting one, be aware that black walnuts produce juglone. This is a natural but toxic chemical they produce to reduce competition for resources from other plants. This natural self-defense mechanism can be harmful to nearby plants causing “walnut wilt.” Having a walnut tree in your landscape, however, certainly does not mean the landscape will be barren. Not all plants are sensitive to juglone. Many trees, vines, shrubs, ground covers, annuals and perennials will grow and even thrive in close proximity to a walnut tree. Production and Effect of Juglone Toxicity Juglone, which occurs in all parts of the black walnut tree, can affect other plants by several means: Stems Through root contact Leaves Through leakage or decay in the soil Through falling and decaying leaves When rain leaches and drips juglone from leaves Nuts and hulls and branches onto plants below. Juglone is most concentrated in the buds, nut hulls and All parts of the black walnut tree produce roots and, to a lesser degree, in leaves and stems. Plants toxic juglone to varying degrees. located beneath the canopy of walnut trees are most at risk. In general, the toxic zone around a mature walnut tree is within 50 to 60 feet of the trunk, but can extend to 80 feet. -
Molecular Analysis of Vanilla Mosaic Virus from the Cook Islands
Molecular Analysis of Vanilla mosaic virus from the Cook Islands Christopher Puli’uvea A thesis submitted to Auckland University of Technology in partial fulfilment of the requirements for the degree of Master of Science (MSc) 2017 School of Science I Abstract Vanilla was first introduced to French Polynesia in 1848 and from 1899-1966 was a major export for French Polynesia who then produced an average of 158 tonnes of cured Vanilla tahitensis beans annually. In 1967, vanilla production declined rapidly to a low of 0.6 tonnes by 1981, which prompted a nation-wide investigation with the aim of restoring vanilla production to its former levels. As a result, a mosaic-inducing virus was discovered infecting V. tahitensis that was distinct from Cymbidium mosaic virus (CyMV) and Odontoglossum ringspot virus (ORSV) but serologically related to dasheen mosaic virus (DsMV). The potyvirus was subsequently named vanilla mosaic virus (VanMV) and was later reported to infect V. tahitensis in the Cook Islands and V. planifolia in Fiji and Vanuatu. Attempts were made to mechanically inoculate VanMV to a number of plants that are susceptible to DsMV, but with no success. Based on a partial sequence analysis, VanMV-FP (French Polynesian isolate) and VanMV-CI (Cook Islands isolate) were later characterised as strains of DsMV exclusively infecting vanilla. Since its discovery, little information is known about how VanMV-CI acquired the ability to exclusively infect vanilla and lose its ability to infect natural hosts of DsMV or vice versa. The aims of this research were to characterise the VanMV genome and attempt to determine the molecular basis for host range specificity of VanMV-CI. -

Agricultural Research Service UNITED STATES DEPARTMENT OF AGRICULTURE Washington, D.C. ISSUED JANUARY 1976 For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C 20402 — Price $7.10 (Paper Cover) Stock Number 0100-02691 FOREWORD The study of fruit tree virus diseases is a tedious process because of the time needed to produce experimental woody plants and, often, the long interval from inoculation until the development of diagnostic symptoms. The need for cooperation and interchange of information among investigators of these diseases has been apparent for a long time. As early as 1941, a conference was called by Director V. R. Gardner at Michigan State University to discuss the problem. One result of this early conference was the selection of a committee (E. M. Hildebrand, G. H. Berkeley, and D. Cation) to collect and classify both published and unpublished data on the nomenclature, symptoms, host range, geographical distribution, and other pertinent information on stone fruit virus diseases. This information was used to prepare a "Handbook of Stone Fruit Virus Diseases in North America," which was published in 1942 as a mis- cellaneous publication of the Michigan Agricultural Experiment Station. At a second conference of stone fruit virus disease workers held in Cleveland, Ohio, in 1944 under the chairmanship of Director Gardner, a Publication Committee (D.
