Project description:rs05-05_atrazine - effect of atrazine and sucrose on arabidopsis transcriptome - Growth in the presence of sucrose was shown to confer to Arabidopsis thaliana seedlings, under conditions of in vitro culture, a very high level of tolerance to the herbicide atrazine and to other photosynthesis inhibitors (Sulmon et al., 2004). The CATMA investigation will be useful to reveal the gene networks implicated in the mechanisms of xenobiotics tolerance. - Seeds of Arabidopsis thaliana (ecotype Columbia) were surface-sterilized inbayrochlore/ethanol (1:1, v/v), rinsed in absolute ethanol and dried overnight. Germination and growth were carried out under axenic conditions in square Petri dishes. After seeds were sowed, Petri dishes were placed at 4degreeC for 48 h in order to break dormancy and homogenize germination, and then transferred to a control growth chamber at 22degreeC under a 16-h light period regime at 4500 lux for 4 weeks. Growth medium consisted of 0.8% (w/v) agar in 1x Murashige and Skoog (MS) basal salt mix (Sigma, St. Louis, MO, USA) adjusted to pH 5.7. After 4 weeks of cultivation on vertical plates plantlets were transferred on fresh medium complemented or not with atrazine 10 uM and with sucrose 80mM or mannitol 80 mM which were directly added during preparation of agar-MS media prior to sterilisation. Atrazine was sterilized by microfiltration through 0.2 um cellulose acetate filters (Polylabo, Strasbourg, France) and then axenically added to melted agar-MS medium prior to pouring into Petri dishes. Then plantlets were harvested after 24 hours of transfer and extracted for RNA. Keywords: treated vs untreated comparison

Project description:Microarrays were used to evaluate the effect of sucrose on gene expression in guard cells. Strips of Arabidopsis leaves were incubated with sucrose or mannitol or no sugars, then the leaves were freeze dried and guard cells were dissected from the leaf strips and analyzed.

Project description:Arabidopsis thaliana is a well-established model system for the analysis of the basic physiological and metabolic pathways of plants. The presented model is a new semi-quantitative mathematical model of the metabolism of Arabidopsis thaliana. The Petri net formalism was used to express the complex reaction system in a mathematically unique manner. To verify the model for correctness and consistency concepts of network decomposition and network reduction such as transition invariants, common transition pairs, and invariant transition pairs were applied. Based on recent knowledge from literature, including the Calvin cycle, glycolysis and citric acid cycle, glyoxylate cycle, urea cycle, sucrose synthesis, and the starch metabolism, the core metabolism of Arabidopsis thaliana was formulated. Each reaction (transition) is experimentally proven. The complete Petri net model consists of 134 metabolites, represented by places, and 243 reactions, represented by transitions. Places and transitions are connected via 572 edges.
