^aAmino acids and other charged osmolytes were not determined in this study.

^bThe role of glutamate as a compatible solute is under debate (70).

^cU, uptake occurred; C, conversion occurred; ND, not determined in the corresponding study.

^d(+), production occurs only when medium conditions mimic in planta conditions.
