We examine the extent to which these viral RNAs have evolved to be physically compact molecules to facilitate encapsulation. Measurements of equal-length viral, non-viral, coding and non-coding RNAs show viral RNAs to have among the smallest sizes in solution, i.e., the highest gel-electrophoretic mobilities and the smallest hydrodynamic radii. Using graph-theoretical analyses we demonstrate that their sizes correlate with the compactness of branching patterns in predicted secondary structure ensembles. The density of branching is determined by the number and relative positions of 3-helix junctions, and is highly sensitive to the presence of rare higher-order junctions with 4 or more helices. -

(SMT 4-CT98-2252) through a partnership of contractor laboratories and intercomparison laboratories in European countries. Approved as an EPPO Standard in 2003-09. Revision approved in 2006-09. Introduction Identity Rhizomania disease of sugar beet was first reported in Italy Name: Beet necrotic yellow vein virus (Canova, 1959) and has since been reported in more than Acronym: BNYVV 25 countries. The disease causes economic loss to sugar beet Taxonomic position: Viruses, Benyvirus (Beta vulgaris var. saccharifera) by reducing yield. Rhizomania EPPO computer code: BNYVV0 is caused by Beet necrotic yellow vein virus (BNYVV), which Phytosanitary categorization: EPPO A2 list no. 160; EU is transmitted by the soil protozoan, Polymyxa betae (family Annex designation I/B. Plasmodiophoraceae). The virus can survive in P. betae cystosori for more than 15 years. The symptoms of rhizomania, Detection also known as ‘root madness’, include root bearding, stunting, chlorosis of leaves, yellow veining and necrosis of leaf veins. The disease affects all subspecies of Beta vulgaris, including The virus is spread by movement of soil, primarily on machinery, sugar beet (Beta vulgaris subsp. maritime), fodder beet (Beta sugar beet roots, stecklings, other root crops, such as potato, vulgaris subsp. vulgaris), red beet (Beta vulgaris subsp. cicla), and in composts and soil. -

Many pentachlorophenol- (PCP-) contaminated environments are characterized by low or elevated temperatures, acidic or alkaline pH, and high salt concentrations. PCP-degrading microorganisms, adapted to grow and prosper in these environments, play an important role in the biological treatment of polluted extreme habitats. A PCP-degrading bacterium was isolated and characterized from arid and saline soil in southern Tunisia and was enriched in mineral salts medium supplemented with PCP as source of carbon and energy. -

To isolate strains, Marine agar medium was basically used and cultivated at 37℃ and pH7 for several days aerobically. After single colony isolation, totally 49 pure single-colonies were iso- lated and phylogenetic analysis was carried out based on the result of 16S rRNA gene DNA sequenc- ing, indicating that isolated strains were divided into 3 phyla, 13 families, 15 genera, 34 species and 49 strains. Proteobacteria phylum, the main phyletic group, comprised 83.7% with 8 families, 8 genera and 26 species of Aeromonadaceae, Pseudoalteromonadaceae, Shewanellaceae, Enterobacteriaceae, Mor- ganellaceae, Moraxellaceae, Pseudomonadaceae, and Vibrionaceae. To confirm whether isolated strain can produce industrially useful enzyme or not, amylase, lipase, and protease enzyme assays were per- formed individually, showing that 39 strains possessed at least one enzyme activity. -

Vainio 2 and Carmen Büttner 1 1 Faculty of Life Sciences, Albrecht Daniel Thaer-Institute of Agricultural and Horticultural Sciences, Humboldt-Universität zu Berlin, Ber- lin, Germany; [email protected], [email protected] 2 Natural Resources Institute Finland, Latokartanonkaari 9, 00790, Helsinki, Finland; [email protected] * Correspondence: [email protected] Abstract: Forest health is dependent on the variability of microorganisms interacting with the host tree/holobiont. Symbiotic mi- crobiota and pathogens engage in a permanent interplay, which influences the host. Thanks to the development of NGS technol- ogies, a vast amount of genetic information on the virosphere of temperate forests has been gained the last seven years. To estimate the qualitative/quantitative impact of NGS in forest virology, we have summarized viruses affecting major tree/shrub species and their fungal associates, including fungal plant pathogens, mutualists and saprotrophs. The contribution of NGS methods is ex- tremely significant for forest virology. Reviewed data about viral presence in holobionts, allowed us to address the role of the virome in the holobionts. Genetic variation is a crucial aspect in hologenome, significantly reinforced by horizontal gene transfer among all interacting actors. Through virus-virus interplays synergistic or antagonistic relations may evolve, which may drasti- cally affect the health of the holobiont. Novel insights of these interplays may allow practical applications for forest plant protec- tion based on endophytes and mycovirus biocontrol agents.
