Although we know that most of the cellular sucrose is present in the cytosol and vacuole, our knowledge on the impact of this sucrose compartmentation on plant properties is still fragmentary. Here we attempted to alter the intracellular sucrose compartmentation of Arabidopsis mesophyll cells by either, overexpression of the vacuolar sucrose loader BvTST2.1 or by generation of mutants with decreased vacuolar invertase activity (amiR vi1-2). Surprisingly, BvTST2.1 overexpression led to increased monosaccharide levels in leaves,...
