Espaço Público: Espetáculo, vigilância e controle

3º congresso – As múltiplas Faces da Arquitetura Contemporânea de 2016 – As múltiplas Faces da Arquitetura Contemporânea – foram apresentados pelos/as estudantes da disciplina de Crítica e História da Arquitetura e da Cidade IV sob orientação da professora Andreia Moassab, do curso de Arquitetura e Urbanismo da Universidade Federal da Integração Latino-americana – UNILA. O congresso é parte da avaliação final da disciplina, no qual os/as estudantes apresentam a sua versão e dialogam com autores/as e textos de referência sobre a arquitetura nas últimas décadasO espaço público tem como característica o coletivo, segundo a pesquisadora Diane Ghirardo. A autora demonstra como este espaço, após a segunda guerra mundial foi repensado. Se no período antecedente o espaço público constituía uma esfera otimista, voltado ao povo, a partir das décadas de 50 e 60, ele passa a ter uma concepção exclusivista, barrado às diferenças que compõem a sociedad

Fruit self-thinning: a trait to consider for genetic improvement of apple tree.

In apple (Malus×domestica Borkh), as in many fruiting crops, fruit maintenance vs abscission is a major criteria for production profitability. Growers routinely make use of chemical thinning agents to control total fruit load. However, serious threats for the environment lead to the demand for new apple cultivars with self-thinning properties. In this project, we studied the genetic determinism of this trait using a F1 progeny derived from the cross between the hybrid INRA X3263, assumed to possess the self-thinning trait, and the cultivar 'Belrène'. Both counting and percentage variables were considered to capture the fruiting behaviour on different shoot types and over three consecutive years. Besides low to moderate but significant genetic effects, mixed models showed considerable effects of the year and the shoot type, as well as an interaction effect. Year effect resulted mainly from biennial fruiting. Eight Quantitative Trait Locus (QTL) were detected on several linkage groups (LG), either independent or specific of the year of observation or the shoot type. The QTL with highest LOD value was located on the top third of LG10. The screening of three QTL zones for candidate genes revealed a list of transcription factors and genes involved in fruit nutrition, xylem differentiation, plant responses to starvation and organ abscission that open new avenues for further molecular investigations. The detailed phenotyping performed revealed the dependency between the self-thinning trait and the fruiting status of the trees. Despite a moderate genetic control of the self-thinning trait, QTL and candidate genes were identified which will need further analyses involving other progenies and molecular investigations

Parameters associated with the QTLs detected by interval mapping (IM) and multiple QTL mapping (MQM) for the genotypic mean values of the total number of inflorescences (NIn), the percentage of inflorescences with one fruit (%In_1fr), the number of fruits per terminal inflorescence (NFI) and fruit set, depending on the year and the shoot type (_08, _09, _C and _L for year 2008, 2008; short and long shoot respectively).

<p>QTLs are represented by boxes, in which bold lines represent the LOD–1 confidence interval and extended lines represent the LOD–2 confidence interval. Boxes representing QTLs for the number of inflorescences are white, those for the number of fruits per inflorescence are black, for the fruitset traits are pale grey, and for the percentage of inflorescences with 1 fruit are dark grey.
