Project description:cea06-01_uranyl_nitrate - time course uranyl nitrate response - Dynamic analyses of transcriptomic response to urany l nitrate - Plants are grown on sand and transfert in hydroponic culture during 2 days and then expose or not to 50uM uranyl nitrate at pH 4.5 in water or only to water at pH 4.5. Roots and leaves were collected independently after 2h, 6h and 30h of treament. Keywords: organ comparison,time course,treated vs untreated comparison

Project description:We preformed at time-course of the expression of whole Arabidopsis roots for 30 minutes, 1H, 3H, 6H 12H, 24H, and 48H after transfer to low pH (pH 4.6). Controls at the standard pH (pH 5.7) were included at each time-point. 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:Expression analysis time-course of Arabidopsis roots to sulfur deficiency
| PRJNA155179 | ENA
Project description:Plants live in soils that vary considerably, both spatially and over time, in terms of nutrient composition and pH. Consistently, plants have to recognize and adapt to these changes by altering their structure and metabolism. The goal of this array analysis is to characterize the global transcriptional response to external pH changes in roots, which to date is almost unexplored. Arabidopsis thaliana (Columbia-0) were grown in hydroponic cultures in basic nutrient solution. Two days before treatment the media was shifted to nutrient solution containing 5mM MES, pH 6. At the time of the treatment start (4 hours after light on) the plants were shifted to nutrient solutions of pH 4.5 and 6.0 (control). Root RNA samples from time point 1 and 8 hour after treatment start is used for array analyzes. Keywords: Expression profilling by array
