Complete Genome Sequences of Six Copper-Resistant Xanthomonas Strains Causing Bacterial Spot of Solaneous Plants, Belonging to X. gardneri, X. euvesicatoria, and X. vesicatoria, Using Long-Read Technology
Full text linkXanthomonas vesicatoria, Xanthomonas euvesicatoria, and Xanthomonas gardneri cause bacterial spot disease. Copper has been applied since the 1920s as part of integrated management programs. The first copper-resistant strains were reported some decades later. Here, we fully sequenced six Xanthomonas strains pathogenic to tomato and/or pepper and having a copper-resistant phenotype.EEA Bella VistaFil: Richard, Damien. CIRAD, UMR PVBMT; Francia.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
CIRM-CFBP : Plan de Gestion des Données
No full textPlan de Gestion des Données du CIRM-CFBP. Le CIRM est un Groupement d'Intérêt Scientifique (GIS) créé en 2004 par INRAE autour de ses collections de micro-organismes (bactéries, levures et champignons filamenteux). Il est Coordonné par INRAE et est constitué de cinq centres de ressources biologique (CRB), tous certifiés ISO 9001. Ces CRB conservent plus de 22 000 souches de bactéries associées aux plantes, bactéries pathogènes, bactéries d'intérêt alimentaire, levures et champignons filamenteux. Le CIRM est labellisé « ISC », Infrastructure Scientifique de Recherche par l’IR RARe. Le CIRM-CFBP est le CRB dédié aux bactéries associées aux plantes. Il est accueilli à l'UMR 1345 IRHS. INRAE
Sélection d'écotypes bactériens pathogènes et non-pathogènes par la plante en relation avec la différenciation en espèces génomiques chez Agrobacterium spp.
No full textThe aims of this work were : 1) to verify the existence of relations between genomic species and plant-associated ecotypes in Agrobacterium genus ; 2) to determine which genomic zones are implied in the ecotype differenciation and thus in the genomic species differenciation in this taxa. Firstly, we determined and caracterised, at the genomic level (by AFLP), non-pathogenic and pathogenic (harbouring a Ti plasmid) ecotypes in different biotopes. Our results show that the plant select specific ecotypes among the agrobacterial soil community. Moreover, some pathogenic strains, isolated from crown galls, are recruited among these particular ecotypes. Secondly, predictive AFLP performed on strain C58 genome, permitted us to identify the AFLP fragments caracteristic of genomic species G8. The genes and functions revealed this way could actually be implied in plant-bacteria relationships.Ce travail avait pour but : 1) de vérifier l'existence d'une relation entre espèces génomiques et écotypes associés aux plantes chez Agrobacterium spp.; 2) d'identifier les zones génomiques impliquées dans la différentiation en écotypes et, partant, en espèces génomiques dans ce taxon. Nous avons d'abord cherché et caractérisé au niveau génomique (par AFLP) des écotypes non-pathogènes et pathogènes (hébergeant un plasmide Ti), dans différents biotopes. Nos résultats montrent que la plante sélectionne des écotypes spécifiques au sein de la communauté des agrobactéries du sol. De plus, il apparaît que c'est parmis les écotypes spécifiques d'une plante donnée que sont recrutées certaines agrobactéries pathogènes isolées des tumeurs. L'AFLP prédictive réalisée sur le génome de la souche C58 nous a ensuite permis d'identifier les fragments AFLP caractéristiques de l'espèce G8. Les gènes et fonctions ainsi révèlées pourraient effectivement concerner des relations plantes-bactéries
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
