1. 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. Transmembrane signalling by a hybrid protein: communication from the domain of chemoreceptor Trg that recognizes sugar-binding proteins to the kinase/phosphatase domain of osmosensor EnvZ.
Chemoreceptor Trg and osmosensor EnvZ of Escherichia coli share a common transmembrane organization but have essentially unrelated primary structures. We created a hybrid gene coding for a protein in which Trg contributed its periplasmic and transmembrane domains as well as a short cytoplasmic segment and EnvZ contributed its cytoplasmic kinase/phosphatase d

4. Nutrient control of gene expression in Drosophila: microarray analysis of starvation and sugar-dependent response
We have identified genes regulated by starvation and sugar signals in Drosophila larvae using whole-genome microarrays. Based on expression profiles in the two nutrient conditions, they were organized into different categories that reflect distinct physiological pathways mediating sugar and fat metabolism, and cell growth. In the category of genes regulated

5. Sex and sugar in yeast: two distinct GPCR systems
Although eukaryotic G-protein coupled receptor (GPCR) systems are well known for their ability to detect and mediate rapid responses to extracellular signals, the full range of stimuli to which they respond may not yet have been identified. Activation of GPCRs by hormones, pheromones, odorants, neurotransmitters, light and different taste compounds is well e

6. Strategies for differential sensory responses mediated through the same transmembrane receptor.
Trg mediates chemotaxis of Escherichia coli to galactose and ribose by recognition of respective, sugar-occupied binding proteins. Although both attractants act through one transmembrane receptor, maximal response is approximately 50% greater to ribose. This phenomenon was investigated by mutational analysis of a 20-residue segment of Trg implicated in ligan

7. Interaction of Azospirillum lipoferum with Wheat Germ Agglutinin Stimulates Nitrogen Fixation
In vitro, the nitrogen fixation capability of A. lipoferum is efficiently increased in the presence of wheat germ agglutinin (WGA). A putative WGA-binding receptor, a 32-kDa protein, was detected in the cell capsule. The stimulatory effect required N-acetyl-d-glucosamine dimer (GlcNAcdi) terminated sugar side chains of the receptor and was dependent on the n

8. 14-3-3s regulate global cleavage of their diverse binding partners in sugar-starved Arabidopsis cells
Despite 14-3-3 proteins being implicated in the control of the eukaryotic cell cycle, metabolism, cell signalling and survival, little is known about the global regulation or functions of the phosphorylation-dependent binding of 14-3-3s to diverse target proteins. We identified Arabidopsis cytosolic proteins that bound 14-3-3s in competition with a 14-3-3-bi
