Abstract
Studies on the compartmentation of alkaloids in a cell suspension of Catharanthus roseus demonstrate that, while unspecific ion trapping in the vacuolar compartment occurs for such such molecules, other accumulation mechanisms also exist in cells. In any cases, a protonmotive force is involved with H+ recycling, in co-transport of solutes, and, with net active H+ influx. To illustrate such a point of view, the latex of Hevea brasiliensis could be examplified.
