Quantitative proteomics of the tonoplast
reveals a role for glycolytic enzymes in salt tolerance.

The vacuole formation can be related to the tonoplast
disruption, forming vesicles and multivesicular bodies (Wei & Miller, 1972).

The V-ATPase creates an electrochemical proton gradient across the tonoplast
, which is used for secondary-active solute uptake mediated by specific transporters, as well as is pivotal to pH homeostasis of the cytoplasm.

It is postulated that TRIA increases the ratio of L (+)- to D(-)- adenosine at the tonoplast
and the most probable source of adenosine is AMP, derived from ADP or ATP (Ries 1991).
