Effect of PAs in enhancing the activity of stress-induced molecular chaperone. Effects of exogenously added-PAs (Put, Spd, and Spm) on heat-mediated malate dehydrogenase (MDH) aggregation was determined. Crude total proteins were isolated from unstressed control and transgenic plants after PAs treatment under salt stress. Light scattering of total proteins was determined using a model substrate MDH (1 μM under thermal denaturing conditions (45°C) for 30 min. Data were expressed as means ± SD from three independent biological replicates. The statistical analysis was performed with two-way ANOVA using GraphPad Prism, comparing NaCl vs. NaCl + Put, NaCl vs. NaCl vs. NaCl + Spd, or NaCl vs. NaCl + Spm. Significant differences are displayed (*P < 0.05; **P < 0.01; ***P < 0.001).
