FIG 1.

Sucrose accumulation in Syn7942 cells challenged by different stresses. (a) Cells were stressed by NaCl, sorbitol, mannitol, and PEG6000 under different osmolality conditions for 4 h. (b) Cells were stressed by NaCl, sorbitol, mannitol, and PEG6000 under the same osmolality (602 mmol/kg) for different times. (c) Cells were stressed by NaCl, KCl, and NaNO₃ under the same osmolality (602 mmol/kg) for different times. The data are presented as means from at least three independent replicates (n = 3 in panels a and c; n = 4 in panel b) with the standard deviations.
