Pathogenic Variation

Isolates of Sphaceloma manihoticola, the asexual stage of Elsinoe brasiliensis, were collected from several regions of south-central Brazil. The isolates were obtained from samples of leaves, stems, and petioles of cassava (Manihot esculenta) and the weedy Euphorbia heterophylla (“amendoim bravo”) by directly plating infected tissue onto acidified potato dextrose agar. For pathogenicity studies, 19 isolates were inoculated onto each of two cassava cultivars, MBRA 703 as a susceptible cultivar and MBRA 12 as a resistant cultivar to S. manihoticola. MBRA 703, with the greatest pathogenicity to 58% (11) of the isolates, showed an intermediate pathogenic reaction to 16% (3) of the isolates, and was less pathogenic to 26% (5) of the isolates. MBRA 12, with a less pathogenic reaction to 63% (12) of the isolates, showed an intermediate pathogenic reaction to 16% (3) of the isolates, and was highly pathogenic to 21% (4) of the isolates. The isolates were verified as belonging to the genus Sphaceloma based on their morphological characteristics, including conidia and hyphae of monoconidial isolate. Conidia of isolates were small, thin-walled, ellipsoid to (rarely) globose, commonly with one or two gut-tules. Conidiophores were phialides, hyaline to slightly pigmented 0-to-1 septate; conidiophores from the weedy specie were phialides, hyaline to brown 0-to-2 septate producing hyaline conidia. The isolates also were verified as belonging to the genus Sphaceloma by using a poly-merase chain reaction (PCR) assay, which detected a 645-bp band in all isolates except two (1 and 6) for which the PCR product had 600 bp. Digestion of the amplified product with the enzymes MspI and CfoI allowed differences to be detected in restriction patterns among isolates. A homogeneous banding pattern was obtained for 17 of the isolates but a different restriction pattern was obtained for isolates 1 and 6 of E. heterophylla. This suggests the possibility of another species within this group of isolates. The results indicate the presence of pathogenic variation among isolates of the fungus and an isolate-host interaction, because statistically significant differences were observed between the two cassava cultivars in response to inoculation with the isolates of S. manihoticola.

Nomina Dubia

The record of dinosaur body-fossils in the Brazilian Mesozoic is restricted to the Triassic of Rio Grande do Sul and Cretaceous of various parts of the country. This includes 21 named species, two of which were regarded as nomina dubia, and 19 consensually assigned to Dinosauria. Additional eight supraspecific taxa have been identified based on fragmentary specimens and numerous dinosaur footprints known in Brazil. In fact, most Brazilian specimens related to dinosaurs are composed of isolated teeth and vertebrae. Despite the increase of fieldwork during the last decade, there are still no dinosaur body-fossils of Jurassic age and the evidence of ornithischians in Brazil is very limited. Dinosaur faunas from this country are generally correlated with those from other parts of Gondwana throughout the Mesozoic. During the Late Triassic, there is a close correspondence to Argentina and other south-Pangaea areas. Mid-Cretaceous faunas of northeastern Brazil resemble those of coeval deposits of North Africa and Argentina. Southern hemisphere spinosaurids are restricted to Africa and Brazil, whereas abelisaurids are still unknown in the Early Cretaceous of the latter. Late Cretaceous dinosaur assemblages of south-central Brazil are endemic only to genus or, more conspicuously, to species level, sharing closely related taxa with Argentina, Madagascar, Indo-Pakistan and, to a lesser degree, continental Africa.

Entre o final dos anos 1990 e o início dos anos 2000, a partir de caminhos próprios ou sob influência das políticas em nível federal, os estados brasileiros dão início às suas políticas de apoio à APLs. A análise de como estas políticas foram implementadas nos estados do Centro-Sul do Brasil é o objetivo principal deste artigo que, analisa, também, os critérios norteadores da seleção dos arranjos focalizados pelas políticas, assim como o escopo, institucionalidade e instrumentos mobilizados para levar a cabo o apoio aos APLs. Ressalta que as principais tipologias para os APLs, cujo foco são os objetivos de política, constituem-se em referencial analítico para avaliar como vem se desenvolvendo o processo de implementação dessas políticas em alguns estados brasileiros. A avaliação empreendida neste trabalho traz, como conclusão principal, uma significativa diversidade nas políticas estaduais de apoio à APLs.Palavras-chave: Arranjos produtivos locais, políticas públicas.ANALYSIS OF SUPPORT LOCAL ARRANGEMENTS PRODUCTIVE POLICIES ON CENTRAL-SOUTH STATES IN BRAZILAbstract: Between the late 1990s and early 2000s, from their own paths or under the influence of central government policies, the Brazilian states initiate their policies to support clusters. The analysis of how these policies were implemented in the states of South-Central Brazil is the main purpose of this paper which also analyzes the guiding criteria of the selection of focused clusters by the policies, as well as the scope, institutionalities and deployed instruments to carry out the support for clusters. The main typologies of clusters, whose focus is on policy objectives, constitute the analytical framework to assess how the policies to support clusters have been developed in some Brazilian states. The assessment undertaken in this work underscores, as main conclusion, a significant diversity in state policies to support clusters. Key words: clusters, public policies
