Members of the genus Agrobacterium constitute a diverse group of organisms, all of which, when harbouring the appropriate plasmids, are capable of causing neoplastic growths on susceptible host plants. The agrobacteria, which are members of the family Rhizobiaceae, can be differentiated into at least three biovars, corresponding to species divisions based on differential biochemical and physiol...
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
We compared the nodulation competitiveness of three strains of Rhizobium leguminosarum by counting the number of nodules formed on faba bean plants after the application at sowing time of different concentrations of the strains to soils already containing Rhizobium strains of the same species. A relationship of type y = ax was found to exist between the ratio of the nodules formed by the applie...
Rhizobium-legume symbiosis begins with two free living organisms, and ends with an intimate cellular co-existence. Rhizobium bacteria recognize specific plants, provoke development of a root nodule, and invade the plant tissue. Eventually, the Rhizobium cell transfers itself into a host cell, surrounds itself with plant membrane, and arranges a nutrient exchange in which the bacteria brings fix...
this thesis examines the significances and implications of inflicted physical pain in waiting for the barbarians (1980) by john maxwell coetzee (1940 - ). the researcher tries to show how body becomes a site for exercising violence. in this way, the government’s representatives turn bodies of the barbarians into blank pages through torturing in order to create the truth of the empire. in this p...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Aim of present study is to evaluate the effect of salinity on the growth of Rhizobium symbiosis with various cultivars of Berseem (WARDAN, BB3, JHB 052 and BB2). Two sets of plots were maintained in which one set contained non-inoculated while another set contained inoculated seeds with Rhizobium culture, which were irrigated with saline waters of different concentrations (0, 3, 6, 7.2, 10, 12 ...
Air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. SO2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. Symbiosis of Rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
