Abstract
  • Maize necrotic streak virus (MNeSV) has 32 nm isometric particles that encapsidate a single stranded RNA genome ca. 4.3 kb in size and is a tentative member of the genus Tombusvirus. Since tombusviruses elicit the formation of cytopathological structures known as \"multivesicular bodies\" that assist in their classification at genus level, the cytology of thinsectioned maize leaf tissues 7, 15 and 45 days after inoculation was investigated. The prominent cytopathological features were: (i) extensive accumulation of virus particles scattered throughout cytoplasm or in crystalline arrays in cytoplasm or, occasionally, in intercellular spaces; (ii) extensive plasmolysis and appearance of small patches of amorphous, dark-staining material in cytoplasm; (iii) proliferation of membranes and presence of empty double membrane-bound vesicular structures of various sizes. No apparent connection between these membranous elements and the nuclear envelope was detected, even when large clusters of vesicles were adpressed to the nuclei. Some of the largest doublemembrane bound structures had rows of small vesicles located inside peripheral dilations of the bounding membrane. Although most of these structures appeared to originate from disintegrating mitochondria, they bore little resemblance to genuine multivesicular bodies like those arising from the modified mitochondria that follow infection by certain members of Tombusviridae, i.e. Carnation Italian ringspot virus, Pelargonium necrotic spot virus (PNSV), Galinsoga mosaic virus (GaMV) and Turnip crinkle virus (TCV). Immunogold labelling using antibodies to virus particles was detected over cytoplasm, associated with virus particles and patches of electrondense amorphous material, suggesting that this material consists of virus coat protein (literal)
  • The AGRIS initiative was set up by the FAO in the 70s and created a worldwide cooperation for sharing access to agricultural science and technology information. Based on available technologies, AGRIS was initially collecting bibliographic references for a central database. However, since the advent of the Internet in the late 90s AGRIS has become the brand name for a network of centres, which are promoting the exchange of agricultural science and technology information through the use of common standards and methodologies. The AGRIS open archives and bibliographical databases cover the many aspects of agriculture, including forestry, animal husbandry, aquatic sciences and fisheries, and human nutrition, extension literature from over 100 participating countries. Material includes unique grey literature such as unpublished scientific and technical reports, theses, conference papers, government publications, and more. AGRIS today is part of the CIARD (Coherence in Information for Agricultural Research for Development) initiative, in which the CGIAR, GFAR and FAO collaborate to create a community for efficient knowledge sharing in agricultural research and development. We encourage all research centres or research information units all over the world to participate in this project. By contacting the AGRIS Secretariat all necessary information to participate will be provided. More information is available in the AGRIS wiki page. (literal)
