13. Desenvolvimento de um modelo para construção de mapas genéticos em autopoliploides, com aplicações em cana-de-açúcar / Development of a model to build genetic maps in autopolyploides, with applications in sugarcane
Autopolyploid species are extremely important in agriculture. However, the complex structure of their genomes is not well understood. Despite all advances in genetic mapping of autotetraploids, the vast majority of the models used for autopolyploid species with high ploidy level, such as sugarcane, are approximations of those used in diploid organisms. Thus,

14. An overview of lignin metabolism and its effect on biomass recalcitrance
Lignin, after cellulose, is the second most abundant biopolymer on Earth, accounting for 30% of the organic carbon in the biosphere. It is considered an important evolutionary adaptation of plants during their transition from the aquatic environment to land, since it bestowed the early tracheophytes with physical support to stand upright and enabled long-dis

15. Analysis of the stress-inducible transcription factor SsNAC23 in sugarcane plants
Stresses such as cold and drought can impair plant yield and induce a highly complex array of responses. Sugarcane (Saccharum spp.) is cultivated in tropical and subtropical areas and is considered a cold-sensitive plant. We previously showed that cold stress induces the expression of several genes in in vitro sugarcane plantlets. Here we characterize one of

16. Análise da via de regulação gênica do miRNA156/SPL na brotação lateral e caracterização molecular do processo de emergência da gema axilar de cana de açucar / Analysis of the role(s) of the miRNA156/SPL pathway on branching/tillering and molecular characterization of sugarcane lateral bud outgrowth
Sugarcane is an economically important biofuel crop that recently has become a target for improvement of sustainable biomaterial production due to its high biomass productivity and built-in containment features. Therefore, studies aiming to improve the production of biomass per area are among the most important issues in sugarcane production. Plant biomass i

18. A atuação do complexo agroindustrial canavieiro em rede : o exemplo de Nova Luzitânia-SP
The aim of this research was to analise the evolution of the production processes and work at the mesoregions of São José do Rio Preto and Araçatuba, mainly at the microregions of Auriflama and Araçatuba specifying the city of Nova Luzitânia. In these was developed the Agro-industrial Complex operating through the geographics nets. In order to better un

19. Avaliação da tolerância ao estresse salino de plantas de cana-de-açúcar transformadas com o gene P5CS
A salinidade pode interferir na produção de cana-de-açúcar de duas maneiras: afetando o crescimento e o rendimento, como também reduzindo a concentração de sacarose no colmo. Plantas submetidas ao estresse salino podem acumular compostos orgânicos não tóxicos de baixo peso molecular, coletivamente conhecido como solutos ou osmólitos compatíveis,

20. Contratos agrários na agroindústria canavieira em Goiás:legalidades e conflitos / Land contracts in the sugarcane industry in Goiás: legalities and conflicts
With the retake of the agro-energetic policies, the Central Government in Brazil was forced to present public policies to stimulate the expansion of the sugarcane agribusiness in the nation. The agroindustrial sector related to the production of juices and sugarcane derivatives in the Goiás state, experiencing a time of great expansion due to the constructi

21. Origin and composition of particulate organic matter in the estuarine-lagoon complex Mundaú-Manguaba using lipids as molecular markers / Origem e composição da matéria orgânica particulada no complexo estuarino-lagunar de Mundaú-Manguaba utilizando lipídios como marcadores moleculares
The Mundaú-Manguaba estuarine lagoon system is located in Maceió, Alagoas, Brazil. This region has been suffering an accelerated process of environmental degradation through many antropic activities like urban growth, sugar-cane processing, cattle breeding, industrials waste and sewage. The aim of this work is to evaluate the suspended particulate matter c

22. Zoneamento edafoclimático e ambiental para a cana-de-açúcar e as implicações das mudanças climáticas no estado do Tocantins / Environmental and edapho-climatic zoning for sugarcane and climatic changes implications for Tocantins State
Due to the increase of ethanol demand, the tendency to expansion of the complex sugarcane industry in the Center-North region requires an elaboration of agroclimatic aptitude for sugarcane culture, especially in Tocantins State. The climatic and edaphic informations favor the determination of most suitable areas for cultivation and mechanization. On the othe

23. Fluxos de emergência, épocas de aplicação de herbicidas e sistemas de manejo de plantas daninhas em cana-de-açúcar / Emergence fluxes, herbicide application timings and weed management systems in sugarcane
The knowledge of the effects of the population dynamics and establishment velocity of weeds on the efficacy of weed management in the sugarcane crop is fundamental for the development of a rational plan of integrated weed management in the crop. Therefore, the objectives of the present research were: (i) to quantify the monthly fluxes of weed emergence year

24. Performance of the parasitoid Cotesia flavipes (Cam.) (Hymenoptera : Braconidae) on Diatraea saccharalis (Fabr.) and Diatraea flavipennella (Box) (Lepidoptera :Crambidae) / Desempenho do parasitóide Cotesia flavipes (Cam.) (Hymenoptera : Braconidae) sobre Diatraea saccharalis (Fabr.) e Diatraea flavipennella (Box) (Lepidoptera :Crambidae)
This complex of sugarcane borers, in Brazil, comprises Diatraea saccharalis (Fabr.) and Diatraea flavipennella (Box) (Lepidoptera.: Crambidae). The control of borers, in Brazil, is the applied biological control using the larval endoparasitoid Cotesia flavipes (Cam.) (Hymenoptera: Braconidae). Recently, however, the biological control of D. flavipennella by
