Saturation transfer difference NMR spectroscopy is used to study non-covalent interactions between four different glycostructure transforming enzymes and selected substrates and products. Resulting binding patterns represent a molecular basis of specific binding between ligands and biocatalysts.
The interactions established between plants and endophytic fungi span a continuum from beneficial to pathogenic associations. The aim of this work was to isolate potentially beneficial fungal endophytes in the legume Lotus tenuis and explore the mechanisms underlying their effects. One of the nine
OBJECTIVE
Two main strategies that allow plants to cope with soil waterlogging or deeper submergence are: (1) escaping by means of upward shoot elongation or (2) remaining quiescent underwater. This study investigates these strategies in Lotus tenuis, a forage legume of increasing importance in
Six extracts were prepared from Alternaria tenuis isolated ATCC 6663, ATCC 16086 and DAOM (Agriculture Canada) 183905 grown separately on two synthetic media, revised tobacco and Czapek's, and their biochemical and immunological properties were examined. High-performance liquid chromatography
The carbohydrate metabolism of the autotrophically grown blue-green alga, Tolypothrix tenuis, was studied. The alga respires glucose, fructose, galactose, and ribose. About 60% of the glucose consumed is converted by starved cells into a glucose polysaccharide. Glucose uptake and O(2) consumption
Kinetic substituent effects have been used to examine the catalytic reaction profile of xylose reductase from the yeast Candida tenuis, a representative aldo/keto reductase of primary carbohydrate metabolism. Michaelis-Menten parameters (k(cat) and K(m)) for NADH-dependent enzymic aldehyde
Cyanobacterial populations introduced into crop fields as biofertilizer become non-target organisms for the pesticides and fungicides applied in the field. Effect of four commonly used pesticides viz. Bagalol, Mancozeb (fungicides), Thiodan and Phorate (insecticides) was studied on growth and
Rapid initiation of clotting is critical to trauma patients. In the present study exopolymers (EPs) from four desert cyanobacteria including Tolypothrix tenuis and three species of Anabaena have been discovered as potential hemostatic biomaterials. The EPs showed reduction in activated partial
Carnivorous plants of the genus Nepenthes supplement their nutrient deficiency by capturing arthropods or by mutualistic interactions, through their leaf-evolved biological traps (pitchers). Though there are numerous studies on these traps, mostly on their prey capture mechanisms, the gas
Five allergen extracts of Dermatophagoides pteronyssinus, Lolium perenne, Alternaria tenuis, Aspergillus fumigatus and Cladosporium herbarum, obtained from four different manufacturers, were examined by inhibition of RAST, content of protein and carbohydrate, contents of phosphorylcholine (Pc) and
In colonial modular organisms, differences in module size and colony growth patterns among species have the potential to impose varying constraints on reproductive investment. Here, we compare reproductive output among seven morphologically different species of spawning reef corals, and analyse the
Most microplastics are expected to sink and end up in marine sediments. However, very little is known concerning their potential impact on sediment-dwelling organisms. We studied the long-term impact of microplastic exposure on two sediment-dwelling bivalve species. Ennucula tenuis and Abra nitida
Tomato leaf miner (TLM), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most destructive tomato pests worldwide. We tested quantity and quality of tomato fruits after simultaneous use of two biological control agents, the predatory mirid bug Nesidiocoris tenuis (Reuter) and the egg
Coral generally harbors zooxanthellae (genus Symbiodinium) in the body for mutualistic symbiosis, which favors the host through effects on growth, stress response, and nutrient utilization. However, little is known about the molecular mechanisms by which the partners establish and regulate the
