O papel do turismo nos conflitos urbanos da cidade do Natal/RN: a história que ninguém quer contar

La présente étude a comme objectif comprendre la relation entre l implantation et le développement du Tourisme à Natal et les conflits urbains établits entre 2006 et 2010 et publiés par les médias imprimés, élaborant ses impacts dans le quotidien des résidents. Tandis qu une relecture partielle de la méthode régressive-progressive développée par le philosophe français Henri Lefebvre, cherche à recouper du présent, des contradictions qui promeuvent des réactions dans le quotidien de la ville; ainsi qu identifier des moments du passé qui puissent contribuer à sa compréhension. Aujourd hui, nous avons les médias, comme principale source pour observer la perception locale des problèmes causés par l espace conçu, à partir des actions de l État référentes à l activité. Par rapport au passé, ces situations sont recherchées dans des sources secondaires, mettant en évidence le dialogue avec le Relatório Conflitos Urbanos (Rapport Conflits Urbains) à Natal-1976-1986 (ANDRADE et al.,1986), qui présente les conflits existants à des moments qui ont précédé ou ont acompagné le début du développement de l activité au RN, spécialement à Natal. Alors que dans la contribution à la compréhension du rôle du Tourisme dans l apparition de conflits urbains de la ville sont aussi inclues nos coupures vécues, des actions de l État par rapport à la consolidation, ainsi comme pour les conflits qui se sont plus demarqués ou qui ont conduit à la réaction de la population de la ville pendant les périodes analysées. Au final, on cherche à démontrer les limites de la responsabilité de l activité touristique dans l urgence des principaux conflits urbains dans la ville. L analyse des données de la recherche, avec l identification des conflits urbains de Natal et sa relation avec le Tourisme; la présentation des conflits par rapport à la localisation, fréquence et son encadrement dans les catégories de l analyse adoptée; l identification des agents intéressés et la relation entre eux; ont amené à la confirmation de l hypothèse proposée. De cette façon, en prenant en compte les coupures temporelles et spatiales, la source de recherche et la méthodologie adoptées, nous arrivons à la conclusion que l activité touristique à Natal n est pas directement responsable de l apparition des conflits urbains de la ville

Phenotypic changes associated with RNA interference silencing of chalcone synthase in apple (Malus × domestica)

We have identified in apple (Malus × domestica) three chalcone synthase (CHS) genes. In order to understand the functional redundancy of this gene family RNA interference knockout lines were generated where all three of these genes were down-regulated. These lines had no detectable anthocyanins and radically reduced concentrations of dihydrochalcones and flavonoids. Surprisingly, down-regulation of CHS also led to major changes in plant development, resulting in plants with shortened internode lengths, smaller leaves and a greatly reduced growth rate. Microscopic analysis revealed that these phenotypic changes extended down to the cellular level, with CHS-silenced lines showing aberrant cellular organisation in the leaves. Fruit collected from one CHS-silenced line was smaller than the 'Royal Gala' controls, lacked flavonoids in the skin and flesh and also had changes in cell morphology. Auxin transport experiments showed increased rates of auxin transport in a CHS-silenced line compared with the 'Royal Gala' control. As flavonoids are well known to be key modulators of auxin transport, we hypothesise that the removal of almost all flavonoids from the plant by CHS silencing creates a vastly altered environment for auxin transport to occur and results in the observed changes in growth and development.

RNA interference silencing of CHS greatly alters the growth pattern of apple (Malus x domestica)

Plants produce a vast array of phenolic compounds which are essential for their survival on land. One major class of polyphenols are the flavonoids and their formation is dependent on the enzyme chalcone synthase (CHS). In a recent study we silenced the CHS genes of apple (Malus × domestica Borkh.) and observed a loss of pigmentation in the fruit skin, flowers and stems. More surprisingly, highly silenced lines were significantly reduced in size, with small leaves and shortened internode lengths. Chemical analysis also revealed that the transgenic shoots contained greatly reduced concentrations of flavonoids which are known to modulate auxin flow. An auxin transport study verified this, with an increased auxin transport in the CHS-silenced lines. Overall, these findings suggest that auxin transport in apple has adapted to take place in the presence of high endogenous concentrations of flavonoids. Removal of these compounds therefore results in abnormal auxin movement and a highly disrupted growth pattern. © 2013 Landes Bioscience.

The genome of the domesticated apple (Malus × domestica Borkh.)

We report a high-quality draft genome sequence of the domesticated apple (Malus × domestica). We show that a relatively recent (>50 million years ago) genome-wide duplication (GWD) has resulted in the transition from nine ancestral chromosomes to 17 chromosomes in the Pyreae. Traces of older GWDs partly support the monophyly of the ancestral paleohexaploidy of eudicots. Phylogenetic reconstruction of Pyreae and the genus Malus, relative to major Rosaceae taxa, identified the progenitor of the cultivated apple as M. sieversii. Expansion of gene families reported to be involved in fruit development may explain formation of the pome, a Pyreae-specific false fruit that develops by proliferation of the basal part of the sepals, the receptacle. In apple, a subclade of MADS-box genes, normally involved in flower and fruit development, is expanded to include 15 members, as are other gene families involved in Rosaceae-specific metabolism, such as transport and assimilation of sorbitol.

História constitucional brasileira : mudança constitucional, autoritarismo e democracia no Brasil pós-1964

Apresenta, com detalhes, aspectos históricos do constitucionalismo contemporâneo brasileiro. Partindo do período pós-1964, quando diversos processos de reforma ou ruptura alteraram as regras relativas a mudanças constitucionais, é apresentado um desenho dos principais instrumentos jurídicos utilizados pelo regime militar a fim de garantir a sua hegemonia política e jurídica. A análise passa pelo processo constituinte de 1987-1988, para verificar em que medida se rompeu com o paradigma instaurado pela ditadura, e investiga as principais tentativas de, sob a vigência da nova Carta Magna, alterar o processo de reforma constitucional.
