Fig. 5From: Modulation of proline metabolic gene expression in Arabidopsis thaliana under water-stressed conditions by a drought-mitigating Pseudomonas putida strainContent of accumulated free proline in A. thaliana on day-2, day-4 and day-7 post treatments. Each bar represents mean ± SE of six replicate samples (each sample represents 100 mg seedlings from one Magenta box). * Significant difference (P ≤ 0.05) in data between NS + NI and any other treatment within a particular day of analysis. ! Significant difference (P ≤ 0.05) between WS + I and WS + NI samples within a particular day of analysis. Statistical analysis was done to compare data between two different treatments by Student’s t-test (two-tailed analysis, P ≤ 0.05) using Microsoft Excel 2010Back to article page
