Suspension-cultured cells of Arabidopsis thaliana were precultured in media with high concentrations of sucrose or sorbitol and their tolerance to desiccation and super-low temperature was examined. The tolerance of the cell to desiccation and super-low temperature substantially increased after preculturing in sucrose- or sorbitol-enriched medium. Osmotic concentration of cell-free extract increased and considerable amounts of sucrose and proline accumulated in the cell during precuturing in sucrose- or sorbitol-enriched medium. It was suggested that the accumulation of these substances play an important role in the development of the tolerance in A. thaliana cells.
