Abstract
Cell lines of Nicotiana sylvestris, both sensitive and resistant to growth inhibition by NaCl, rapidly accumulated free proline on transfer from NaCl-free medium to medium containing 1.5 0/o (w/v) NaCl. Proline accumulated more rapidly in the sensitive cell line and the levels detected did not seem sufficient for it to act as an effective cytoplasmic osmoticum. None of the other amino acids detected exhibited comparable changes and the total of free amino acids other than proline was similar, in both lines, in the presence or absence of NaCl.
Proline accumulation is considered either to be symptomatic of salt-induced stress, or to have a protective role other than as an osmotic regulator.
