El área de gestión de la información y del conocimiento como frente de investigación en la Ciencia de la Información brasileña: análisis de la producción científica en el período 2000-2009

The management of information and knowledge has been one of the areas of expertise of the fastest growing Brazilian information science. The purpose of this work is to observe how this research front structure from the point of view of the subjects that compose and intellectual frameworks which supports. For this we have analyzed the content of scientific production published in four majo r national journals of the discipline: Ciência da Informação, DataGramaZero, Perspectivas em Ciência da Informação and Transinformação over 2000-2009. The methodology is based on co-occurrence analysis of keywords of articles and co-citation analysis of authors. For the representation and interpretation of the results are used to social network analysis (SNA). We conclude that both information management and knowledge management are closely linked areas within topics including approaches but no consensus answer from the point of view of intellectual frameworks referenced.

Rhizoctonia solani GA-3PT es el principal patógeno asociado con el chancro del tallo y la sarna negra de la papa en Colombia

Stem canker and black scurf diseases of potatoes are caused by the basidiomycetous fungus Tanatephorus cucumeris (ana-morphic species complex Rhizoctonia solani). Tese diseases have worldwide distribution wherever potato is grown but their etiology varies depending on the predominance of distinct R. solani anastomosis groups (AGs) in a particular area. Within the species complex, several AGs have been associated with stem canker or black scurf diseases, including AG-1, AG-2-1, AG-2-2, AG-3, AG-4, AG-5 and AG-9. Tis article reports on the most comprehensive population-based study, providing evidence on the distribution of R. solani AGs in Colombian potato fields. A total of 433 isolates were sampled from the main potato cropping areas in Colombia from 2005 to 2009. Isolates were assigned to AGs by conventional PCR assays using specific primers for AG-3, sequencing of the ITS-rDNA and hyphal interactions. Most of the isolates evaluated were assigned to AG-3PT (88.45%), and a few to AG-2-1 (2.54%). Te remaining isolates were binucleate Rhizoctonia (AG-A, E, and I). Pathogenicity tests on the stems and roots of different plant species, including the potato, showed that AG-3PT affects the stems of solanaceous plants. In other plant species, damage was severe in the roots, but not the stems. AG-2-1 caused stem canker of Solanum tuberosum cv. Capiro and in R. raphanistrum and B. campestris subsp. Rapa plantlets and root rot in other plants. Te results of our study indicated that R. solani AG-3PT was the principal pathogen associated with potato stem canker and black scurf diseases of potatoes in Colombia.
