ABSTRACT Overwintering of tobacco thrips, Frankliniella fusca, was investigated on common winter annual host plants infected with Tomato spotted wilt virus (TSWV). Populations of tobacco thrips produced on TSWV-infected plants did not differ from those produced on healthy plants, whereas populations varied greatly among host plant species. The mean per plant populations of F. fusca averaged 401...
Thermobifidas are thermotolerant, compost inhabiting actinomycetes which have complex polysaccharide hydrolyzing enzyme systems. The best characterized enzymes of these hydrolases are cellulases from T. fusca, while other important enzymes especially hemicellulases are not deeply explored. To fill this gap we cloned and investigated endomannanases from those reference strains of the Thermobifid...
Epiphytic yeasts, which colonize plant surfaces, may possess activity that can be harnessed to help plants defend themselves against various pathogens. Due to their unique characteristics, epiphytic yeasts belonging to the genus Pseudozyma hold great potential for use as biocontrol agents. We identified a unique, biologically active isolate of the epiphytic yeast Pseudozyma aphidis that is capa...
We investigated the effect of injections of four biogenic amines (serotonin, dopamine, octopamine and tyramine) on behavior patterns displayed by workers of the red wood ant Formica polyctena during dyadic confrontations with four types of opponents: a nestmate, an alien conspecific, an allospecific ant (Formica fusca), and a potential prey, a nymph of the house cricket (Acheta domesticus). Sig...
Phyllosphere microbiota play a crucial role in plant-environment interactions and their microbial community and function are influenced by biotic and abiotic factors. However, there is little research on how pathogens affect the microbial community of phyllosphere fungi. In this study, we collected 16 pumpkin (Cucurbita moschata) leaf samples which exhibited powdery mildew disease, with a sever...

The ability of a parasite strain to establish and grow on its host may be drastically altered by simultaneous infection by other parasite strains, and dynamics under multiple infection have been suggested to be a major force driving pathogen evolution. Here, I studied whether hosts' induced defenses mediate dynamics of multiple infection of the fungal pathogen, Podosphaera plantaginis, infectin...
Microalgae are considered to be potentially attractive feedstocks for biodiesel production, mainly due their fast growth rate and high oil content accumulated in cells. In this study, the suitability biofuel production was tested Chlorella vulgaris, fusca, Oocystis submarina, Monoraphidium strain. The effect of nutrient limitation on microalgae biomass growth, lipid accumulation, ash content, f...
Bacteria belonging to the order Actinomycetales have proven to be an important source of biologically active and often therapeutically useful natural products. The characterization of orphan biosynthetic gene clusters is an emerging and valuable approach to the discovery of novel small molecules. Analysis of the recently sequenced genome of the thermophilic actinomycete Thermobifida fusca revea...
Almost complete 16S rRNA sequences from seven Thermomonospora strains, Thermomonospora curvata, Thermomonospora formosensis, Thermomonospora fusca, Thermomonospora mesophila, Thermomonospora chromogena, Thermomonospora alba and Thermomonospora mesouviformis (a synonym of Thermomonospora alba) were determined and subjected to phylogenetic analysis together with the sequences from all the represe...
