Figure 1

Effect of Pi availability on the sulfate and Pi contents in Arabidopsis tissues. Wild-type (wt) plants as well as the phr1, sultr1;3 and sultr2;1 mutant plants were grown on medium containing 1 mM Pi for 7 days, followed by an additional 4 days in media containing either 1 mM Pi (+Pi) or no Pi (-Pi). Shoots and roots were harvested separately and Pi (upper histograms) and sulfate (lower histograms) concentrations were quantified using high-pressure ionic chromatography. Individual measurements were obtained from the analysis of shoots or roots collected from a pool of 'n' plants (n ≥ 10). Error bars indicate SD; biological repeats (n ≥ 3). The star indicates a significant difference with WT plants (ANOVA and Tukey test, P < 0.05).
