Project description:There are two principal mechanisms underlie sugar perception and signal transduction in biological systems. Direct sensing and signaling is triggered by sugar direct binding sensors such as Hexokiase 1 (HXK1) with a broad range of affinity and specificity, and indirect sensing signaling via a variety of energy and metabolite sensor, such as Target of Rapamycin (TOR). To investigate the intertwined interaction between glucose and plant hormones ethylene, the transcriptome regulated by ethylene, glucose-TOR, and glucose-HXK1 were analyzed and compared. Our results unexpectedly revealed a deep antagonistic interaction between glucose-TOR-energy signaling and the plant stress hormone ethylene.

Project description:During germination, the availability of sugars, oxygen, or cellular energy fluctuates under dynamic environmental conditions, and the global RNA profile of rice genes can be affected by their availabilities. In the aerobically germinating rice embryos, most sugar-regulated genes are responsive to low energy and anaerobic conditions, indicating that sugar-regulation is closely associated with energy and anaerobic signaling. The interference pattern of sugar-regulation by either anaerobic or low energy conditions indicates that induction is likely the more prevalent regulatory mechanism than repression for the alteration in the expression of sugar-regulated genes in aerobically germinating rice embryos. Among the aerobically sugar-regulated genes, limited genes exhibit sugar regulation under anaerobic conditions, indicating that anaerobic conditions strongly influence sugar-regulated gene expression. Anaerobically responsive genes are highly overlapped with low-energy responsive genes. In particular, the expression levels of anaerobically downregulated genes are consistent with those induced by low energy-conditions, suggesting that anaerobic downregulation results from the prevention of aerobic respiration due to the absence of the final electron acceptor, i.e., molecular oxygen. It was noted that abscisic acid (ABA)-responsive genes were over-representative of the genes upregulated under low energy conditions, in contrast to the downregulated genes. This suggests that either ABA itself or upstream signaling components of the ABA signaling pathway are likely to be involved in the signaling pathways activated by low energy conditions.

Project description:We compared gene expression in the Drosophila fat body on control and high-sugar diets in order to gain insight into the role of this organ during caloric overload. Differential expression analysis revealed changes in gene expression suggestive of a role for CoA metabolism in the ability to tolerate high-sugar feeding. This led us to perform biochemical and mutant studies supporting a model where CoA is limiting in the face of caloric overload.

Project description:Streptococcus pneumoniae is a strictly fermentative human pathogen that relies on carbohydrate metabolism to generate energy for growth. The nasopharynx colonised by the bacterium is poor in free sugars, but mucosa lining glycans can provide a source of sugar. In blood and inflamed tissues glucose is the prevailing sugar. As a result during progression from colonisation to disease S. pneumoniae has to cope with a pronounced shift in carbohydrate nature and availability. Thus, we set out to assess the pneumococcal response to sugars found in glycans and the influence of glucose (Glc) on this response at the transcriptional, physiological and metabolic levels. Galactose (Gal), N-acetylglucosamine (GlcNAc) and mannose (Man) affected the expression of 8 to 14% of the genes covering cellular functions including central carbon metabolism and virulence. The pattern of end-products as monitored by in vivo 13C-NMR is in good agreement with the fermentation profiles during growth, while the pools of phosphorylated metabolites are consistent with the type of fermentation observed (homolactic vs. mixed) and regulation at the metabolic level. Furthermore, the accumulation of -Gal6P and Man6P indicate metabolic bottlenecks in the metabolism of Gal and Man, respectively. Glc added to cells actively metabolizing other sugar(s)was readily consumed and elicited a metabolic shift towards a homolactic profile. The transcriptional response to Glc was large (over 5% of the genome). In central carbon metabolism (most represented category), Glc exerted mostly negative regulation. The smallest response was observed on a sugar mix, suggesting that exposure to varied sugars improves the fitness of S. pneumoniae. The expression of classical virulence factors was negatively controlled by Glc in a sugar-dependent manner. Overall, our results shed new light on the link between carbohydrate metabolism, adaptation to host niches and virulence. Two conditions with the same strain (D39), including a dye swap

Project description:Beet necrotic yellow vein virus (BNYVV) and Beet soil-borne mosaic virus (BSBMV) belong to the genus Benyvirus. Both viruses share a similar genome organization, but disease development induced in their major host plant sugar beet displays striking differences. BNYVV induces excessive lateral root (LR) formation by hijacking auxin-regulated pathways; whereas BSBMV infected roots appear asymptomatic. To elucidate transcriptomic changes associated with the virus-specific disease development of BNYVV and BSBMV, we performed a comparative transcriptome analysis of a virus infected susceptible sugar beet genotype.
