Treatment of sub-MIC levels of (±)-catechin on A. thaliana seedlings. (A) A. thaliana plants growing in solid MS full strength media were supplemented with different concentrations of (±)-catechin (1–20 µg ml−1). Post ten days of treatment plants were evaluated for total biomass (fresh weight basis). All data presented are the mean values of five replicates, and the data have been presented as means with standard errors of the means. Means with different letters are significantly different at p ≤ 0.05, according to Duncan’s multiple-range test. (B) A. thaliana plants growing in liquid MS full strength media were supplemented with different concentrations of (±)-catechin (0.02–100 µg ml−1). Post ten days of treatment plants were evaluated for total biomass (fresh weight basis). All data presented are the mean values of five replicates, and the data have been presented as means with standard errors of the means. Means with different letters are significantly different at p ≤ 0.05, according to Duncan’s multiple-range test.
