A study of cashew nut shell liquid purification and the synthesis of nonionic surfactants from the component phenols
… the synthesis of some novel macrocycles and some sugar transport studies.

Haemolymph sugar homeostasis and the control of the proventriculus in the honeybee (Apis mellifera carnica L.)
… variables (haemolymph osmolarity and haemolymph sugar titer) affect each other and which of these factors controls the activity of the proventriculus in the honeybee. Therefore free-flying foragers were trained to collect con-trolled amounts of different sugar solutions. Immediately after …

THE TRANSCRIPTIONAL PROGRAM OF GOLGI BIOGENESIS
… as glycosylation, membrane tethering, and ion/sugar transport. These findings suggest the existence of a master regulator that orchestrates the simultaneous expression of components required for the structural and functional integrity of the organelle. Through bioinformatic and in vitro …

Biochemistry and regulation of CheA in Bacillus subtilis chemotaxis
… system revealed that taxis toward certain sugars is mediated solely through a separate phosphoenolpyruvate-dependent phosphotransferase system (PTS), involved in sugar transport. In B. subtilis, we have determined that taxis toward PTS carbohydrates is mediated both by MCPs and the PTS. …

Investigating Rhizobium Leguminosarum Metabolism and Rhizosphere Colonization Using High-Throughput Genomics and Erythritol Enrichments
… previously thought; including stress mitigation, sugar transport, and rhizosphere quorum sensing. The results suggest that erythritol may act as a chemical signal that triggers a specialized response in R. leguminosarum 3841 to out-compete other soil bacteria in colonizing the rhizosphere, thereby …

Microarray-based differential gene expression of listeria monocytogenes cultures grown as biofilms and planktonic cells
… adaptation and protection, transcription, transport, and motility factors, chemotaxis, and several with unknown functions. Among those genes to be down-regulated in biofilm cells were those involved in cell structure, metabolism, biosynthesis, transcriptional regulators, sugar transport, …

A sorghum NAC gene is associated with variation in vascular development, biomass properties, and yield potential
… goals for crop breeding include maximizing sugar and grain yield while maintaining the rigidity and strength of the stalk. Vascular architecture influences not only stalk strength and rigidity, but also water, nutrient and sugar transport, which ultimately determine grain yield. The building …

A combinatorial approach for improved target prediction, validation, and characterization of small RNAs in Escherichia coli
… and eight new targets for GcvB (amino acid transport/metabolism). For RyhB, the new targets cybB, yciS, and hypB were activated, whereas narG was repressed when RyhB was overexpressed. GcvB repressed genes cysB, sucC, ebgR, cstA, yhjE, acs, and trpE and activated dtpB. All in all, we were …

Engineering Zymomonas mobilis for the production of biofuels and other value-added products
… it can efficiently produce ethanol from simple sugars using unique metabolic pathways. Z. mobilis displays what is known as the “uncoupled growth” phenomenon, meaning cells will rapidly convert sugars to ethanol regardless of their energy requirements for growth. This makes Z. mobilis attractive …

Physiological roles and regulation of the cryptic prophage-encoded small protein DicB and small RNA DicF in Escherichia coli
… canonical function of ManYZ, which is mannose sugar transport. We demonstrated that the previously known interaction between DicB and MinC, a host protein involved in proper positioning of the Z ring during cell division, is necessary for the DicB-dependent phenotypes involving ManYZ identified …

Transposon Tagging in Strawberry and Potato and Characterization of Representative Strawberry Mutants
… during anther culture. A strawberry mutant with sugar transport deficiency due to T-DNA insertion near a sucrose transporter-2 gene showing stunted phenotype with increased level of anthocyanin was also characterized. The concentrations of sucrose, glucose, and fructose were significantly greater …

Biophysikalische Untersuchung von Phloem-lokalisierten Carriern und Kaliumkanälen und deren Interaktion im Modellsystem der Xenopus Oozyte
… Phloems im Wesentlichen vom Zusammenspiel eines Transportmoduls, bestehend aus Carriern, Kaliumkanälen und Protonen-ATPasen, bestimmt. Ausgangspunkt für die biophysikalische Charakterisierung dieses Phloem-Transportmoduls waren Arbeiten zum Saccharosetransport in der Arabidopsis akt2/3-1 Mutante. …

Engineering Zymomonas mobilis for efficient fuel ethanol production from lignocellulosic feedstocks
… has been engineered to ferment all of the sugars present in cellulosic biomass, but the digestion of five carbon sugars by the strain is still slow and inefficient. The inefficiencies are present because Z. mobilis displays preferential sugar digestion—only after all six carbon sugars in …

Drosophila as a model for the Anopheles Malpighian tubule
… Malpighian tubules contain many ion channels and transporters, they could be an effective tissue for targeting with novel pesticides to control populations of Diptera. Many of the insecticide compounds used to control insect pest species are no longer suited to their task, and so new means of …

Regulation of the Mannose PTS Operon by the small RNA SgrS
… of glycolytic flux and accumulation of sugar-phosphates. SgrS has been shown to stimulate degradation of the ptsG mRNA, encoding the major glucose transporter. This study demonstrates that SgrS regulates the genes encoding the mannose and secondary glucose transporter, manXYZ. Analysis …
