On the hydrodynamics of plasmodesmata
Journal of Theoretical Biology, 1978Abstract The effects of geometry, type of fluid and properties of the desmotubule membrane on the fluid transport in plasmodesma are discussed from a hydrodynamics viewpoint. It is shown that the “necking” of the ends of plasmodesma has a profound effect on the volume flow rates reducing them by several orders of magnitude.

Plasmodesmata: composition, structure and trafficking
Plant Molecular Biology, 1994Plasmodesmata are highly specialized gatable trans-wall channels that interconnect contiguous cells and function in direct cytoplasm-to-cytoplasm intercellular transport. Computer-enhanced digital imaging analysis of electron micrographs of plasmodesmata has provided new information on plasmodesmatal fine structure.

Plasmodesmata (Vegetable Kingdom)
1957In 1879 E. Tangl described minute structures which traverse the cell walls of the endosperm of Strychnos nux-vomica, Phoenix dactilifera and Areca oleracea (Tangl 1879, see Fig. 1). From his observations and some microchemical tests he concluded that these structures are “offene Communicationen” (open communications) or “Protoplasmafortsatze ...

It is remarkable that many viruses are able to move so freely through their host plants, despite the fact that virus particles or infective virus nucleic acids are so very much larger than the molecules, such as sugars and amino acids, for which plant translocation systems were presumably ‘designed’. But they do move, and surprisingly quickly.

Plasmodesmata are narrow strands of cytoplasm that connect neighbouring plant cells, penetrating through the intervening cell walls (Fig. 1.1.). The plant physiologist sees them as structures which elevate a plant from a mere collection of individual cells to an interconnected commune of living protoplasts. Cells and tissues that are remote from direct

Intercellular communication: Regulation of plasmodesmata
Current BiologyIntercellular channels called plasmodesmata regulate cell-cell communication in plants. A new study now reveals how the levels of phosphatidylinositol 4-phosphate and the interaction with MCTP proteins can control trafficking via plasmodesmata in plants.
