Under the continuous pressure of Dutch elm disease (DED) in Europe, increasing genetic diversity Ulmus minor trees resistant to Ophiostoma novo-ulmi is a priority for species conservation and reintroduction. In this work we screened 121 U. genotypes resistance O. under field experimental conditions. The had been previously obtained through controlled crosses between two moderately (dams) one su...
greenhouse-grown red pine seedling, Pinus resinosa, when cultured on malt agar or potato dextrose agar (PDA) showed inhibitory activity against selected test fungi. Sensitive fungi included Ceratocystis ulmi (BUISM.) C. MOREAU, Pythium spp., Rhizoctonia solani KUHN, Cylindrocarpon sp., Fusarium oxysporum SCHLECT., and Sirococcus strobilinus PREUSS. When grown on PDA, a colorless crystalline sol...
Ameroseius is the largest genus of the mite family Ameroseiidae (Mesostigmata), with a worldwide distribution. Ameroseius norvegicus Narita, Abduch & Moraes n. sp. is described based on the morphology of adult females collected from litter in a strawberry field, in Norway. The new species is most similar to Ameroseius ulmi Hirschmann. A key is provided to separate them as well as other similar ...
As part of the DNA Sequencing Research Group of the Association of Biomolecular Resource Facilities, we have tested the reproducibility of the Roche/454 GS-FLX Titanium System at five core facilities. Experience with the Roche/454 system ranged from <10 to >340 sequencing runs performed. All participating sites were supplied with an aliquot of a common DNA preparation and were requested to cond...
Introduction Up to 80% of post-stroke patients present upper-limb motor impairment (ULMI), causing functional limitations in daily activities and loss independence. UMLI is seldom fully recovered after stroke when using conventional therapeutic approaches. Functional Electrical Stimulation Therapy (FEST) controlled by Brain–Computer Interface (BCI) an alternative that may induce neuroplastic ch...
A Gram-positive, short, rod-shaped, cream-coloured actinobacterium, designated MSL-04(T), was isolated from a soil sample collected from an agricultural field on Bigeum Island (Republic of Korea) and was subjected to polyphasic characterization to unravel its taxonomic position. The optimum growth temperature and pH were 28-30 degrees C and pH 7.2-7.4. Chemotaxonomic characteristics such as B2b...
Clonal organisms with occasional sex are important for our general understanding of the costs and benefits that maintain sexual reproduction. Cyclically parthenogenetic aphids are highly variable in their frequency of sexual reproduction. However, studies have mostly focused on free-living aphids above ground, whereas dispersal constraints and dependence on ant-tending may differentially affect...
Current approaches in schema mapping and matching focus on pair-wise comparison of schemas. This chapter gives an overview of how n-way comparison of schemas via a unified data model for large-scale multi-schema integration (ULMI) can benefit to schema matching and mapping processes. The approach integrates a set of input schemas into one comprehensive representation. Thus, a unified data model...
This report presents a survey of previous and more recent ultrastructural and cytochemical investigations of disease development in elm, caused by Ophiostoma novo-ulmi, with results of some comparative studies of other wilt diseases caused by f.spp., of Fusarium oxysporum and of Verticillium sp. For cytochemical studies, probes complexed to colloidal gold to detect cellulose, pectin, chitin, an...
