PREMISE OF THE STUDY Primers were designed to produce short amplicons containing single-nucleotide polymorphisms (SNPs) in β-tubulin (tubB) and translation elongation factor 1-α (tefA) in Epichloë canadensis (Clavicipitaceae), an endophytic fungus of Elymus canadensis (Poaceae). METHODS AND RESULTS Primers to amplify regions of tubB and tefA containing suspected SNPs were designed and tested ...
Application of a high-performance liquid chromatography-based muramic acid assay with precolumn fluorescence derivatization to quantification of root-associated bacteria was studied both in pure cultures and in the rhizosphere of axenic Festuca rubra seedlings. Quantities of muramic acid from acid-hydrolyzed cells of Frankia strains, Streptomyces griseoviridis, Enterobacter agglomerans, Klebsie...
Inter-sexual segregation between habitats or between sites within a habitat is very widespread in sexually dimorphic ungulates. As an explanation, it has been suggested that males, because of their larger forage requirements, are driven from preferred, high quality forage habitats into marginal habitats of lower forage quality but higher forage biomass by female competition (`indirect competiti...
The Festuca genus is thought to be the most numerous genus of the Poaceae family. One of the most agronomically important forage grasses, Festuca pratensis Huds. is treated as a model plant to study the molecular mechanisms associated with tolerance to winter stresses, including frost. However, the precise mapping of the genes governing stress tolerance in this species is difficult as its karyo...
The fungal family Clavicipitaceae includes plant symbionts and parasites that produce several psychoactive and bioprotective alkaloids. The family includes grass symbionts in the epichloae clade (Epichloë and Neotyphodium species), which are extraordinarily diverse both in their host interactions and in their alkaloid profiles. Epichloae produce alkaloids of four distinct classes, all of which ...
Entomopathogenic fungi (EPF) are cosmopolitan soil borne pathogens that cause epizootics in various insect orders. EPF isolates of Metarhizium brunneum and M. pinghaense have shown the potential for use as biological agents important agricultural pests. The aim current study was to test persistence on apple bark over a period three weeks, under laboratory conditions. Apple sprayed with conidial...
