1. "Reação de famílias de cana-de-açúcar (Saccharum sp.) em relação a Meloidogyne incognita (Kofoid &White, 1919) Chitwood, 1949" / Reaction of sugarcane families (Saccharum sp.) to Meloidogyne incognita (Kofoid &White, 1919) Chitwood,1949
The sugarcane crop has a special significance to the Brazilian economy that is a leading producing country. This crop is attacked by several pathogens and, amongst them are the nematodes of the genera Meloidogyne, that reduces the sugarcane yield. The use of chemical control, crop rotation, use of antagonistic plants and genetic control by introducing resist

2. Sinalização por carboidratos em cana-de-açucar e divergencia evolutiva / Sugar signaling in sugarcane and evolution diversification
Besides act as carbon primary source in the major types of cells, sugars produced by photosynthesis acquired important functions in the course of plant s evolution like controlling growth, development, and metabolism and acting in resistance to abiotic and biotic stresses like osmotic, energetic and response to pathogens. Sugars can be signals that active si

3. Identificação e caracterização de genes induzidos por Diatraea saccharalis (Lepidoptera: Crambidae) em cana-de-açúcar / Identification and characterization of genes induced by Diatraea saccharalis (Lepidoptera: Crambidae) in sugarcane
As plantas respondem ao ataque de insetos pela indução e acumulação de um conjunto grande de proteínas de defesa. Nesse trabalho foi feita uma investigação sobre as modificações transcricionais que ocorrem em plantas de cana-de-açúcar, em resposta ao ataque de lagartas de Diatraea saccharalis. A primeira abordagem foi o estudo detalhado da induç�

4. Efeitos de inibidores de proteinases de soja em organismos não-alvo associados à cultura da cana-de-açúcar / Effects of soybean proteases inhibitors on non-target organisms associated to sugarcane
Genes of plants expressing insect proteinase inhibitors have been introduced into plants for pest control. Proteases inhibitors are present in plant tissues, mainly in seeds, and act in response to predators and pathogens. The Bowman-Birk type and Kunitz type of serine proteases inhibitors (PI) from soybean seeds are been used to increase resistance of sugar

5. Estudo in silico de genes que codificam fatores de transcriÃÃo responsivos Ãseca, salinidade e congelamento nos genomas do eucalipto, cana e arroz
Abiotic stresses are the most responsable for causing changes in plant growth and development. The plants, in counterpart, make use of a variety of responses in order to maintain their metabolic and physiological processes. One of the main plants responses to environmental conditions alterations is the additional regulation of expression. Moreover, the biosy

6. CaracterizaÃÃo de genes de resistÃncia a patÃgenos em eucalipto (Eucalyptus ssp.), cana-de-aÃÃcar (Saccharumssp.) e feijÃo-caupi (Vigna unguiculata)
Os genes de resistÃncia (R) respondem pela primeira interaÃÃo entre planta e patÃgeno, sendo responsÃveis pela ativaÃÃo ou nÃo de mecanismos de resistÃncia em plantas. Este trabalho analisou genes R em sequÃncias expressas de eucalipto, cana-de-aÃÃcar e feijÃo-caupi, geradas atravÃs de bibliotecas produzidas a partir de diferentes tecidos em v�

7. Análise da expressão gênica induzida por Diatraea saccharalis em cana-de-açúcar via macroarranjos de colônias bacterianas. / Analysis of expressed genes induced by Diatraea saccharalis in sugarcane using bacterial colonies arrays.
Large-scale sequencing and the application of expressed sequence tag (EST) technology has led to the identification of hundreds of thousands of genomic sequences from various organisms. Through projects like the Sugarcane Expressed Sequence Tag (SUCEST), DNA arrays technology could be applied in monitoring gene expression. The first step of this work was to

8. Polimorfismos de seqüência nucleotídica em fragmentos genômicos de cana-de-açúcar homólogos a genes de resistência. / Single nucleotide polymorphims in genomic fragments of sugarcane homologous to resistance genes.
The objective of this work was to investigate the existence of single nucleotide polymorphisms (SNPs) in genomic fragments homologous to resistance genes in sugarcane. For this purpose, primers were designed based on the sequence of the extremities of an identified expressed sequence tag (ESTs) similar to the Xa1 gene of rice (EST SCCCCL3080E03.g) and anothe

9. Mechanisms of sugarcane response to herbivory
Deciphering plant-insect interactions at the molecular level is one of the major topics of interest in contemporary plant biology research. In the last few years, various aspects of the plant response to insect damage have been investigated, including the characterization of direct and indirect responses, the regulation of gene expression resulting from inse
