Double-stranded RNA (dsRNA) viruses are common to all fungal classes and although these viruses do not always cause disease symptoms, the presence of certain dsRNA viruses have been associated with reduced virulence (hypovirulence) in O. -

Viruses Virus Diseases Poaceae(Gramineae)
Viruses and virus diseases of Poaceae (Gramineae) Viruses The Poaceae are one of the most important plant families in terms of the number of species, worldwide distribution, ecosystems and as ingredients of human and animal food. It is not surprising that they support many parasites including and more than 100 severely pathogenic virus species, of which new ones are being virus diseases regularly described. This book results from the contributions of 150 well-known specialists and presents of for the first time an in-depth look at all the viruses (including the retrotransposons) Poaceae(Gramineae) infesting one plant family. Ta xonomic and agronomic descriptions of the Poaceae are presented, followed by data on molecular and biological characteristics of the viruses and descriptions up to species level. Virus diseases of field grasses (barley, maize, rice, rye, sorghum, sugarcane, triticale and wheats), forage, ornamental, aromatic, wild and lawn Gramineae are largely described and illustrated (32 colour plates). A detailed index Sciences de la vie e) of viruses and taxonomic lists will help readers in their search for information. Foreworded by Marc Van Regenmortel, this book is essential for anyone with an interest in plant pathology especially plant virology, entomology, breeding minea and forecasting. Agronomists will also find this book invaluable. ra The book was coordinated by Hervé Lapierre, previously a researcher at the Institut H. Lapierre, P.-A. Signoret, editors National de la Recherche Agronomique (Versailles-France) and Pierre A. Signoret emeritus eae (G professor and formerly head of the plant pathology department at Ecole Nationale Supérieure ac Agronomique (Montpellier-France). Both have worked from the late 1960’s on virus diseases Po of Poaceae . -

To determine which other viruses are associated with soybean thrips, the metatranscriptome of soybean thrips, collected by the Midwest Suction Trap Network during 2018, was analyzed. Contigs assembled from the data revealed a remarkable diversity of virus-like sequences. Of the 181 virus-like sequences identified, 155 were novel and associated primarily with taxa of arthropod-infecting viruses, but sequences similar to plant and fungus-infecting viruses were also identified. -

The Effect of Potyvirus Resistance on Maize Lethal Necrosis (Mln)
THE EFFECT OF POTYVIRUS RESISTANCE ON MAIZE LETHAL NECROSIS (MLN) THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By VICTORIA BIKOGWA BULEGEYA Graduate Program in Horticulture and Crop Science The Ohio State University 2016 Master's Examination Committee: Professor DAVID M. FRANCIS “Advisor” Professor MARGARET G. REDINBAUGH “Co-advisor” Professor PETER R. THOMISON Copyrighted by VICTORIA BIKOGWA BULEGEYA 2016 Abstract Maize lethal necrosis (MLN) is a viral disease of corn (Zea mays L.) currently affecting farmers in East and Central Africa. MLN is caused by a combined infection of Maize chlorotic mottle virus (MCMV) and any potyvirus. In East Africa, MLN was reported to be caused by a combined infection of MCMV and Sugarcane Mosaic virus (SCMV). Most of African maize germplasm is susceptible to the disease and there are no known sources of resistance. Resistance to MCMV has not been well studied but tolerant germplasm has been reported in the US. Resistance to the potyvirus pathogens of maize is well studied and sources of resistance are known and published. This study utilize available potyvirus resistance sources to control MLN and to link potyvirus resistance to white maize endosperm color which is preferred by consumers in Sub Saharan Africa. Lines with different QTL for potyvirus resistance were screened against MLN using artificial inoculation and natural infestation. Genotypes used for the study were Recombinant inbred lines (RIL) derived from Oh1VI, a line known for multi-virus resistance, and Oh28 which is a susceptible parent. Genotypes, with QTL for potyvirus resistance on chromosome 3, 6 and 10 alone and in combination were selected and screened against MLN. -
Data Sheet on Maize Lethal Necrosis (MLN) Disease
Leibniz Institut DSMZ GmbH, Plant Virus Department, Inhoffenstraße 7 b, 38124 Braunschweig, GERMANY Data Sheet on Maize Lethal Necrosis (MLN) Disease Maize lethal necrosis is a serious disease of maize which from its first appearance in Kenya in 2011 (Wangai et al., 2012) is now found in many countries of East Africa where maize is grown. The maize lethal necrosis disease (syn. corn lethal necrosis, CLN) is known to naturally affect varieties of maize (Zea mays) resulting in chlorotic mottling of the leaves, severe stunting and necrosis, often leading to plant death. MLN is caused by a mixed infection between Maize chlorotic mottle virus (MCMV, genus Machlomovirus) and potyviruses infecting maize. In Kenya and other countries, most frequently it is Sugarcane mosaic virus (SCMV) in synergism with MCMV causing MLND. Single infections of MCMV or SCMV cause only mild mosaic or mottling symptoms and a moderate reduction of growth (Fig. 1). In mixed infections, early infected plants appear stunted and show a general chlorosis, leaf bleaching and necrosis. Fig.1: Symptoms of MCMV and SCMV on maize. Maize infected with SCMV (left), MCMV (middle) and synergistic effect of mixed infection of MCMV and SCMV (right and cutout detail). Both, MCMV and SCMV are readily transmitted by mechanical means and are known to be seed transmitted. In addition, MCMV can be experimentally transmitted by thrips (Cabanas et al., 2013) while SCMV is vectored by aphids. Infectious isolates available at DSMZ Collection no.: Original host: Geographic origin: MCMV PV-1087 Zea mays Kakamega, Kenya SCMV PV-0731 Zea mays Borsdorf, Germany SCMV PV-0368 Zea mays Freiburg, Germany Virus diagnosis: Identification of MLND and the viruses involved in the disease complex is generally by observation of symptoms in the field. -
