Proline in Protoplasts: The Chemical Potential of Proline and Stress Sensitivity of Cells

Proline and some other compatible solutes accumulate in plants in response to environmental stress. The stress factors (high and low temperature, salinity, water deficit), physiological responses towards stress and the functional aspect of proline accumulation have been reviewed by Paleg and Aspinall (1981) and Miflin (1980).
