Abstract: in bean (phaseolus vulgaris) producing areas of paraná state, bean rugose mosaic virus (brmv) has been found in mixed infections with bean golden mosaic virus (bgmv) increasing the severity of symptoms and crop losses. the association of cowpea severe mosaic virus (cpsmv) with bud blight symptoms in soybean (glycine max) plants was recently observed in paraná for the first time. in this work rt-pcr products of 600 bp of brmv-pr rna2 and 594 bp of cpsmv-pr rna2 were cloned and sequenced. the amino acid sequences coded by the rna2 segment from these isolates were compared with sequences of the same rna2 genomic region of six comovirus species from the genbank. the cpsmv-pr showed 85% homology with the cpsmv rna2 from the genbank. moreover, the brmv-pr isolate showed 39 and 44% homology with cpsmv and bean pod mottle virus (bpmv), respectively. this work shows, for the first time, partial sequencing data for brmv. this data may be helpful for the complete molecular characterization of this virus and for establishing strategies to obtain virus resistant plants.

Abstract: this work was carried out in order to identify bemisia tabaci (genn.) biotypes present in the state of paraná and to determine their geographical distribution and host plants. about 50 adults were collected in several host crops, weeds and ornamental plants in north, northwest, northeast, west and central areas of the state, from january to may, 1998 and 1999. the species were identified by means of rapd-pcr, using the primer operon h-16. whitefly populations were detected mainly from february on, in both years, seldom achieving more than one adult per leaf. the insect was found in only 66% of the sampled areas. bean golden mosaic was almost never observed during the period. both biotype a and biotype b of b. tabaci were found in the state of paraná, the last one being more restricted to the north region. although biotype b was found colonising a wider range of host plants, it has not spread out in all the state and most of the whitefly specimens found are still the biotype a. a banding pattern distinct of those obtained for a and biotype b of b. tabaci was obtained exclusively with the populations collected from cassava, thus indicating the possible presence of a biotype specific for this crop.

Abstract: compaction is a process that can occur in soils managed inadequately, affecting crop growth and yield directly or indirectly. the shoot development was evaluated as a function of different degrees of subsoil compaction in soybean, corn, cotton, and brachiaria brizantha plants grown in pots filled with soil material from a dystrophic dark-red latosol, with water supply through subsurface irrigation. the experiment was carried out in screened greenhouse at the school of agronomy and veterinary medicine of ufmt, in rigid pvc pots with 195 mm internal diameter in a completely randomized design in a 4 × 5 factorial scheme (four species and five soil densities - 1.0; 1.2; 1.4; and 1.5 mg m-3). the water content in the soil/pot system was maintained above 60% of its maximum water retention capacity. at the end of the experiment, the plant height was measured and the plants cut at ground level; the leaf area estimated, and cotton, corn and soybean yield and the shoot dry matter evaluated. soil densities above 1.4 mg m-3 led to significant reduction in the development of shoot growth of cotton, corn, and soybean, while in brachiaria brizantha plants the reduction was verified only at a density of 1.5 mg m-3. soybean presented the largest increment of the evaluated characteristics at a density of 1.2 mg m-3. brachiaria brizantha presented higher tolerance to compaction, whereas cotton plants were the most sensitive to effects of soil compaction. in general, the quadratic model adequately explained the growth of the studied plants as a function of soil compaction.

Abstract: Nas áreas produtoras de feij o (Phaseolus vulgaris) do Estado do Paraná observa-se anualmente a ocorrência do vírus do mosaico em desenho do feijoeiro (Bean rugose mosaic virus, BRMV), principalmente em infec es mistas com o vírus do mosaico dourado do feijoeiro (Bean golden mosaic virus, BGMV), acarretando maior severidade de sintomas e causando perdas na produ o. Recentemente constatou-se a presen a do vírus do mosaico severo do caupi (Cowpea severe mosaic virus, CPSMV) associado a sintomas de queima do broto em planta es de soja (Glycine max) na regi o de Londrina, sendo este um fato novo no Estado. Neste trabalho, parte do RNA2 de dois comovirus isolados de soja no Paraná foram clonados e sequenciados, sendo 600 pares de bases (pb) do BRMV-PR e 594 pb do CPSMV-PR. Posteriormente, as seqüências correspondentes de aminoácidos foram comparadas com seis seqüências de vírus do gênero Comovirus depositadas no GenBank. Com base nestes dados observou-se que o segmento do RNA2 do isolado CPSMV-PR apresentou homologia de 85% com parte de uma seqüência já conhecida do RNA2 do CPSMV, enquanto que o segmento do RNA2 do isolado BRMV-PR apresentou homologia de 39% com o CPSMV, e de 44% com o Bean pod mottle virus (BPMV). Este trabalho apresenta pela primeira vez dados de sequenciamento parcial do BRMV, o que poderá contribuir para sua completa caracteriza o molecular e para o estabelecimento de estratégias para obten o de plantas resistentes ao vírus.

Abstract: plants of bean (phaseolus vulgaris), showing symptoms of stunt, stem necrosis and chlorotic mosaic, similar to those induced by virus infection were found in a bean field in londrina, paraná. electron microscopy examinations showed isometric virus particles in the cell cytoplasm. double immunodifusion serological tests with antiserum for southern bean mosaic virus (sbmv) gave positive results when tested against plant sap from infected bean plants. the virus was purified and the molecular mass of its coat protein was estimated as 30 kda, the expected value for the coat protein of viruses from the genus sobemovirus. the host range of the virus was restricted to bean and some soybean (glycine max) cultivars. it was possible to separate two isometric viruses commonly found in bean based on the immunity reaction of crotalaria sp., chenopodium quinoa and mucuna deeringiana to sbmv, and on the susceptibility reaction of the same hosts to bean rugose mosaic virus (brmv).

Abstract: This article analyses the reform of the Justice of the Peace, provided for by the legislative decree n. 274/2000. This law introduces some changes in the Italian justice system: a faster proceeding than in other Courts, the institutions of the immediate claim and the low degree of seriousness of the crime, two new types of punishments (community service and house imprisonment), the reconciliation between the victim and the offender and, for the first time, the victim has achieved a greater importance and a central role.Moreover, some documents that belong to the Tribunal of Justice of Peace in Bologna have been studied. The data discussed in the article are referred to dismissed cases and sentences which became final in 2002 to 2006.Cet article analyse la réforme de la justice de paix aux termes du décret législatif n° 274 du 28 ao t 2000. Cette loi a introduit plusieurs nouveautés dans le système de justice italien. En particulier, se sont mises en place des mesures aidant à une justice plus rapide (par example, grace à la possibilité de déclarer l'extinction de l'infraction à la suite d'une conduite réparatrice), des sanctions qui visent à resocialiser et pas seulement à punir (le travail d'intérêt général et la détention domiciliaire), et des mesures permettant de privilégier la réconciliation des parties.Enfin, les données d'une recherche réalisée sur une série de dossiers pénaux jugées et classées par les juges de paix du Tribunal de Bologne sont présentées.
