Fresh wt (mg/100 seedlings ± se) of Arabidopsis seedlings exposed for 5 d to various concentrations of NaCl and cyclic nucleotides (cNMP)
| Treatment
|
||||||
|---|---|---|---|---|---|---|
| −NaCl/−cNMP | −NaCl/100 cNMP | 100 NaCl/−cNMP | 100 NaCl/+10 cNMP | 100 NaCl/+30 cNMP | 100 NaCl/+100 cNMP | |
| cGMP | 56 ± 2.9 | 55 ± 2.2 | 15 ± 1.2 | 19 ± 1.1 | 22 ± 3.0 | 29 ± 3.1 |
| cAMP | 54 ± 2.3 | 53 ± 1.8 | 16 ± 2.0 | 28 ± 3.1 | 25 ± 2.3 | 35 ± 3.0 |
All plants were grown on 50% Murashige and Skoog medium for 8 d before treatment, after which fresh wt was 31 ± 1.8 mg. cNMP (cAMP and cGMP) concentrations are given in micromoles and were added to the growth medium as membrane-permeable analogs. NaCl concentrations are 0 or 100 mm.
