Project description:This experiment was annotated by TAIR (http://arabidopsis.org). This experiment studies the response of gene expression in roots of 25-35 day old plants grown on hydroponics after 6, 48 and 96 hours of potassium starvation. RNA from roots was extracted after transfer to control (control) or potassium free nutrient solution respectively (starvation).

Project description:Background: Over application of phosphate fertilizers in modern agriculture contaminates waterways and disrupts natural ecosystems. Nevertheless, this is a common practice among farmers, especially in developing countries as abundant fertilizers are believed to boost crop yields. The study of plant phosphate metabolism and its underlying genetic pathways is key to discovering methods of efficient fertilizer usage. The work presented here describes the first genome-wide resource on the molecular dynamics underpinning the response and recovery in roots and shoots of Arabidopsis thaliana to phosphate-starvation. Results: Genome-wide profiling revealed minimal overlap between root and shoot transcriptomes suggesting two independent phosphate-starvation regulons. Novel gene expression patterns were detected for over 1000 candidates and were classified as either initial, persistent, or latent responders. Comparative analysis to AtGenExpress identified novel cohorts of genes co-regulated across multiple stimuli. The hormone ABA displayed a dominant role in regulating many phosphate-responsive candidates. Analysis of co-regulation enabled the determination of primary versus redundant members of closely related gene families with respect to phosphate-starvation. Thus, among others, we show that PHO1 acts in shoot, whereas PHO1;H1 is likely the primary regulator in root. Conclusion: Our results uncover a much larger, staged responses to phosphate-starvation than previously described. To our knowledge, this work describes the highest resolution of genome-wide data on plant nutrient stress to date.

Project description:In this study we investigated the transcriptional response of the yeast Saccharomyces cerevisiae to potassium starvation. To this end yeast cells were grown for 60 min in media without potassium or in media with a standard potassium concnetration (50 mM KCl). Using Serial Analysis of Gene Expression (SAGE)-tag sequencing the effect of potassium starvation on the transcriptome was determined.
