Physiological Control of Plasmodesmal Gating

  • Chapter
Plasmodesmata

Abstract

From the start, a freshly divided plant cell is linked to its neighbors by plasmodesmata, offering a symplasmic pathway for the exchange of solutes. During differentiation as well as at maturity, however, the properties of adjacent cells, including the active set of enzymes and the metabolite levels, may be different. Dissimilarity and autonomy of individual cells can develop only if plasmodesmal passage is controlled. Indeed, a transient uncoupling of cells was shown for neighbouring cells that renewed mitotic activity asynchronously (Ehlers and Kollmann1996).
