Ester linked (A) Coumaric Acid) (B) Ferulic Acid levels in wild type (WT) and cpm2 destarched root cell wall (RCW) material under control and severed rought stress conditions. Both the metabolites in the cell wall-bound state were less in roots exposed to drought in cpm2. Three-week-old WT and cpm2 seedlings were either kept well-watered, and their roots were sampled at day 22, or watering was stopped to initiate severe stress condition. Root samples were harvested in control and severe stress condition. WT and cpm2 are represented by blue and red bars, respectively. Data represents mean value ± standard error (SE); n = 5. Stars (^* and ^**) denote statistical significance (P ≤ 0.05 and P ≤ 0.01), respectively, between the two genotypes in a Student's t-test.
