Additional evidence supporting the role of vacuolar transport in salt tolerance has been provided by A. thaliana plants overexpressing a vacuolar H -PPiase [40]. Transgenic plants overexpressing AVPl, coding for the vacuolar H -pyrophosphatase, displayed enhanced salt tolerance that was correlated with the increased ion content... 

Pang et al. [107] demonstrated that in the early stages of seed development in M. truncatula, it is possible to detect the presence of epicatechin-3-O-glucoside (E3G) that is thought to be the vacuolar transport of epicatechin. However, its fate inside the vacuole is still not known. The levels of E3G decrease to zero with the increase of the PA content, which suggests that hydrolysis occurs and that epicatechin is incorporated in the PA polymer. The exact nature of the molecular species that undergo polymerization and the mechanism of assembly in PAs is still unknown [94]. However, there are a few hypotheses trying to explain how this may occur, but aU the models stated until now seem to fail at some point.
