I'd  like his name. Thank you for telling us about his work.

Vacuole storage is the one possibility for holding anything in solution.  It is
a "lake" in the cell for keeping dissolved compounds. There is always a limit to
salinity, but there are plants naturally tolerant to higher concentrations in
the vacuole solution.
