Project description:bra-inra09-01_bioen - cordycepin - Diversification of the Molecular Mechanisms Involved in the Control of the Energetic Balance in Angiosperms - To evaluate the importance of mRNA stability control in glucose signaling, genome wide RNA transcript levels changes will be evaluated in response to short term treatments with glucose or glucose plus abscisic acid (ABA) under conditions of transcriptional inhibition in Arabidopsis. The underlying mechanisms will be investigated for a selected number of co-regulated genes (transcription factors, kinases).

Project description:We preformed at time-course of the expression of whole Arabidopsis roots for 3H, 12H, 24H, 48H and 72H after transfer to media lacking sulfur. We combined these data with 13 other datasests and performed a meta-analysis to ask whether a universal stress response exists in Arabidopsis roots. Stress responses in plants are tightly coordinated with developmental processes, but the interaction between these pathways is poorly understood. Here we use genome-wide assays at high spatial and temporal resolution to understand the processes that lnk development and stress in the Arabidopsis root. Our meta-analysis finds little evidence for a universal stress response. Common stress responses appear to exists and, analagous to animal systems, many of them show cell-type specificity, suggesting a convergent evolutionary theme in multicellular organisms. Common stress responses may be mediated by cell identity regulators, as mutations in these genes resulted in altered responses to stress. Our results reveal surprising linkages between stress and development at cellular resolution, and show the power of multiple genome-wide datasets to elucidate biological processes.
Project description:Genome-wide mapping of gene-microbiome interaction: implication in behavior and effect on microbiome and metabolome. Data was generated on a Thermo Q Exactive and C18 RP UHPLC. Positive polarity acquisition on LC-MS/MS.

Project description:The goal of this experiment was to explore the molecular network of glucose-TOR signaling in Arabidopsis seedling autotrophic transition stage. We used the whole-genome microarrays to detail the global program of gene expression mediated by glucose and TOR.
