Abstract: phanerogam species reserve nutrients in their seeds in order to sustain propagation. their chemical composition and the way the metabolites are used vary, according to genotype, the environment and the interaction between these factors. as the jatropha is considered a strategic oilseed crop in biofuel production, the aim of this work was to quantify the major reserve components (starch, protein, soluble sugar and lipid) of the jatropha seed and its disposition in the cells during different periods of germination, in order to understand the process of reserve mobilisation and to determine the potentially right time for the extraction of vegetable oil for that species. the seeds were soaked in water for 0; 12; 24; 36; 42; 45 and 48 hours, following a completely randomised design and evaluated for wet and dry biomass, chemical characteristics of the reserves and the disposition of the reserve compounds. through research, it was observed that the levels of lipids increased up to 43% at the moment of protrusion. the carbohydrate levels, in both the endosperm and the embryo are minimal during protrusion and shortly after, indicating the maximum use of carbohydrates in the germination process. greatest protein synthesis occurs with the greatest moisture gain, with a reduction in and agglomeration of protein bodies during embryo root growth after protrusion. despite the presence of starch in the endosperm of jatropha curcas l., starch cannot be considered a source of sugars during the period of germination studied.

Abstract: In the present research the use of a microwave oven for the soil moisture content determination was analyzed, comparing the results with the values given by the conventional oven drying, using nine soils, with different textures. The results obtained by either method did not show appreciable differences for the soil samples. When the microwave oven was used, the variation among replicates decreased with the sample size and with the fine particles percentage in the soil. The regression analysis showed that a power law, y = kxn, adjusted the date with a large correlation (R = 0.9997) for all the soils. The n exponent values, near to the unity, indicated that the water removal mechanism showed a behavior near to the linearity in function of the time and that neither the initial water content nor the soil mass influenced the process. The k values in the regression equations showed that the process acts more intensively on clayey soils than on sandy ones. The experimental results allowed to conclude that the microwave oven may be used as an alternative to soil content measurement, resulting in time economy. No presente trabalho estudou-se a utiliza o do forno de microondas na determina o da umidade no solo, comparando-se os resultados com os valores fornecidos pelo método da estufa convencional, usando-se nove solos, com diferentes texturas. Os resultados obtidos por meio de qualquer um dos dois métodos n o diferiram entre si. Quando se usou o método do microondas, as varia es entre repeti es diminuíram com o tamanho da amostra e com a percentagem de partículas finas no solo. A análise de regress o entre as variáveis tempo e umidade apresentou ajuste potencial do tipo y = kxn, com elevada correla o (R = 0,9997) para todos os solos estudados. Os valores do expoente n, todos próximos da unidade, indicaram que o mecanismo de retirada da água por microondas apresentou um comportamento quasi-linear em fun o do tempo e que os teores de umidade inicial e a massa de solo n o influenciaram o processo. Os valores de k nas equa es de regress o indicaram que o processo de secagem no forno de microondas tem maior efeito sobre solos argilosos em rela o àqueles arenosos. O forno de microondas pode ser empregado na determina o da umidade em solos, ocasionando significativa economia de tempo.

Abstract: the most traditional method to determine the soil-water retention curve is based on the richards' pressure plate apparatus. for practical reasons, cheaper and faster alternatives to the richards' apparatus are needed. therefore, this study evaluated the use of the filter paper method. initially, an oxisol was sampled and physically characterized. undisturbed soil samples were prepared and tested in richards' chamber, at pressures of 0, 10, 30, 60, 100, 300, 500, 1,000 and 1,500 kpa. in the filter paper test, the water matric potential was measured in samples for which moisture levels had been determined by an appropriate calibration curve. the tests obtained pressure versus moisture points that were adjusted by the van genuchten model, using the retc program. a comparative analysis of the soil moisture values estimated by the model adjusted in the filter paper test and the adjusted retention curve obtained by the richards' apparatus was performed. results allowed the conclusion that the filter paper method is suited to determine the water retention curve of the agricultural soil studied.

Methicillin-Resistance in Staphylococcus aureus Is Not Affected by the Overexpression in Trans of the mecA Gene Repressor: A Surprising Observation
Duarte C. Oliveira, Hermínia de Lencastre
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0023287
Abstract: Methicillin-resistant Staphylococcus aureus (MRSA) is intrinsically cross-resistant to virtually all β-lactam antibiotics. The central determinant for the MRSA phenotype is the mecA gene, whose transcriptional control may be mediated by a repressor (mecI) and a sensor/inducer (mecR1). The mecI-mecR1-mediated induction of mecA takes several hours rendering the strains phenotypically susceptible in spite of the presence of the resistance gene. Therefore, it has been proposed that the full resistance to β-lactams observed in many contemporary clinical MRSA strains requires a non-functional mecI-mecR1 regulatory system. The mecA gene is embedded in a large chromosomal cassette (the SCCmec element) for which several structural types have been described. Some epidemic MRSA clones, typically expressing full β-lactam resistance, carry SCCmec elements that contain an intact mecI-mecR1 locus (e.g. SCCmec types II and III). We have addressed this apparent contradiction by first sequencing the mecI coding region and mecA promoter sequences in a collection of prototype MRSA strains characterized by different SCCmec types. A conserved non-sense mutation within mecI was detected in all SCCmec type III strains tested, presumably responsible for a non-functional truncated MecI protein and, therefore, explaining the full resistance phenotype. In SCCmec type II strains no conserved mutations were found. We next transformed a collection of prototype MRSA epidemic strains with a recombinant plasmid overexpressing a wild-type copy of mecI. Surprisingly, for the great majority of the strains no significant alterations in the phenotypic expression of β-lactam resistance could be detected. These findings were confirmed and further explored, challenging the currently accepted mechanism of mecA transcriptional control. Our observations suggest the existence of yet unidentified additional determinants involved in the transcriptional control of mecA gene and point to a revision of the mecA regulatory mechanism in contemporary MRSA strains.
