Abstract: 
Solute compartmentation in cells is an important component of metabolic regulation. There is only little information on how stress treatment of cells this component. Therefore, the effect of water stress [10% (w/v) PEG 6 000] on the vacuolar-extravacuolar proline compartmentation was studied in a cell suspension culture of Solanum tuberosum L. cv. HH258. In non-stressed cells 34% of the total cellular proline was located in the vacuole. After 20 h of water stress the proline pool of the cells was increased 4-6 fold and only 16% of it was found in the vacuole. A negative correlation between the total cellular proline content and its percentage in the vacuole was observed, irrespective of the culture method (stress or non-stress culture). The stress-induced changes in proline compartmentation are discussed.
