Bradyrhizobium ingae sp. nov., isolated from effective nodules of Inga laurina grown in Cerrado soil

Root-nodule bacteria were isolated from lnga laurina (Sw.) Willd. growing in the Cerrado Amazon region, State of Roraima, Brazil. The 16S rRNA gene sequences of six strains (BR 10250(T), BR 10248, BR 10249, BR 10251, BR 10252 and BR 10253) showed low similarities with currently described species of the genus Bradyrhizobium. Phylogenetic analyses of sequences of five housekeeping genes (dnaK, gyrB, recA and rpoB) revealed Bradyrhizobium iriomotense EKO5(T) to be the closest type strain (97.4% sequence similarity or less). Chemotaxonomic data, including fatty acid profiles [with the major components C-16:0 and summed feature 8 (C-18:1 omega 6c/C-18:1 omega 7c)], the slow growth rate and carbon compound utilization patterns supported the assignment of our strains to the genus Bradyrhizobium. Results from DNA DNA hybridizations and physiological traits differentiated our strains from the closest related species of the genus Bradyrhizobium with validly published names. Sequences of symbiosis-related genes for nodulation (nodC) and nitrogen fixation (nifH) grouped together with those of B. iriomotense EKO5(T) and Bradyrhizobium sp. strains BR 6610 (used as a commercial inoculant for Inga marginata in Brazil) and TUXTLAS-10 (previously observed in Central America). Based on these data, the six strains represent a novel species, for which the name Bradyrhizobium ingae sp. nov. is proposed. The type strain is BR 10250(T) (=HAMBI 3600(T))

The influence of an organisation's perceived market orientation on the personality trait profile of its salespeople

D.Comm.The market orientation construct describes the behaviours and activities necessary for an organisation to become market oriented - in other words reflect its adoption of the marketing concept. In this study an organisation's perceived level of market orientation was determined using salespeople to assess the extent to which their organisations exhibited market oriented behaviours. The results obtained revealed that on the whole salespeople tend to see their organisation as having above average levels of market orientation. Market oriented organisations provide salespeople with a support system that enable them to provide their customers with optimal satisfaction since everyone in the organisation is focused on this objective. Salespeople operating in market oriented organisations will tend to experience less role stress than those salespeople operating in organisations with lower levels of market orientation. Salespeople with certain personality traits are better able to cope with role stress and therefore these individuals would probably be found in organisations with low levels of market orientation. In this study the personality trait profiles of salespeople working for organisations with different perceived levels of market orientation were determined and the results obtained were correlated with their perceptions of their organisations level of market orientation. The results obtained revealed that there was a correlation between two of the salesperson's personality traits namely, gregarious and energies and their organisation's perceived level of market orientation. The personality dimensions measured in this study were also used to develop a model whereby one could predict 68% ofthe overall respondents correctly in terms of their customer or competitor orientations. Two factors namely apprehensive and conservative, with a negative loading entered into the model in this order, would enable one to predict the salesperson's dominant orientation
