Background and Purpose: Mycorrhizal fungi are of high importance for functioning of forest ecosystems and they could be used as indicators of environmental stress. The aim of this research was to analyze ectomycorrhizal community structure and to determine root colonization rate with ectomycorrhizal, arbuscular mycorrhizal and endophytic fungi of poplars growing on pyrite tailings contaminated ...

schwannoma is a benign encapsulated slow-growing tumor that originates from schwann cells of the peripheral nerve sheath. it usually occurs in the head and neck; however, it is rare in the oral cavity. the tongue is the most common site of intraoral schwannomas, followed by the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area. we report a rare case of schwannom...

Scaling-up knowledge of land-atmosphere net ecosystem exchange (NEE) from a single experimental site to numerous perennial grass fields in the Northern Great Plains (NGP) requires appropriate scaling protocols. We addressed this problem using synoptic data available from the Landsat sensor for 10 growing seasons (April 15 to September 30) over a North Dakota field-site, where we continuously me...

Lipoteichoic acid (LTA) is an important cell wall component required for proper cell growth in many Gram-positive bacteria. In Listeria monocytogenes, two enzymes are required for the synthesis of this polyglycerolphosphate polymer. The LTA primase LtaP(Lm) initiates LTA synthesis by transferring the first glycerolphosphate (GroP) subunit onto the glycolipid anchor and the LTA synthase LtaS(Lm)...

NH(2) terminal analysis of polyphenylalanine formed from 30S subunit-bound (14)C-phenylalanyl-tRNA suggests that there is only one site in a 30S subunit for specific binding of phenylalanyl-tRNA. Assuming that no movement of the bound phenylalanyl-tRNA takes place during association of 30S subunits with 50S ribosomal subunits, the binding site of the 30S ribosomal subunit corresponds to site 2 ...

Gas flaring is now recognized as a major environmental problem. Smoking flare may be significant contributor to overall particulate emissions. It also results in production of excessive heat the nearby areas. The present investigation aims study impact elevated soil temperature on physiological parameters tea plant growing adjacent site. experimental plot was laid out 5 x 2 factorial RCBD with ...
