Rice-NaCl or Na2SO4 toxicity

A comparative transcriptomic study of the impact of salt toxicity on rice plant (Oryza sativa L.; cv 'I Kong Pao') after short term (48 hours) exposure to NaCl (200 mM) or Na2SO4 (100 mM). Twenty five days old rice seedlings were exposed to 0, 200 mM NaCl or 100 mM Na2SO4 for 48 hours in hydroponic culture. Comparison between control and salt-stressed plants were done at the shoot and the root levels. The essays were replicated twice on two independent plant cultures. 12 samples, three condition experiment, control (0 mM NaCl or Na2SO4) vs. salt-treated (200 mM NaCl or 100 mM Na2SO4). Biological replicates: 2 replicates (taking control as reference) for comparison NaCl-stressed shoot, Na2SO4-stressed shoot, NaCl-stressed root, Na2SO4-stressed root and 2 replicates (taking NaCl as reference) for comparison Na2SO4-stressed shoot as well as Na2SO4-stressed root.
