Callose balancing at plasmodesmata. [PDF]
Journal of Experimental Botany, 2018 In plants, communication and molecular exchanges between different cells and tissues are dependent on the apoplastic and symplastic pathways. Symplastic molecular exchanges take place through the plasmodesmata, which connect the cytoplasm of neighboring cells in a highly controlled manner.

Plasmodesmata and plant cytoskeleton
Trends in Plant Science, 2001Plant cell-to-cell communication is achieved by membranous conduits called plasmodesmata, which bridge the cytoplasm of neighboring cells. A growing body of immunolocalization data shows an association of the cytoskeleton machinery with plasmodesmata.

Plasmodesmata 2010: plasmodesmata down under
Protoplasma, 2010More than 60 attendees from more than a dozen countries attended the International Plasmodesmata Meeting (Plasmodesmata 2010) held in Sydney, Australia. The structure of plasmodesmata continued to attract interest, with particular focus on how technological progress is advancing our ability to identify and characterise proteins associated with ...

At only 50 nm in diameter, plasmodesmata (PD) are below the limit of resolution of conventional light microscopy. Consequently, much of our current interpretation of the substructure of PD is derived from transmission electron microscopy. However, PD can be imaged with alternative techniques, including field emission scanning electron microscopy and ...

ABSTRACT Plasmodesmata are cytoplasmic communication channels that are vital for the physiology and development of all plants. They facilitate the intercellular movement of various cargos – ranging from small molecules, such as sugars, ions and other essential nutrients and chemicals, to large complex molecules, such as proteins and ...

Plasmodesmata form and function
Current Opinion in Cell Biology, 2004Intercellular transport via plasmodesmata controls cell fate decisions in plants, and is of fundamental importance in viral movement, disease resistance, and the spread of RNAi signals. Although plasmodesmata appear to be unique to plant cells, they may have structural and functional similarities to the newly discovered tunneling nanotubes that connect

Plasmodesmata (PD) are plasma membrane lined pores that cross the plant cell wall and connect adjacent cells. Plasmodesmata are composed of elements of the endoplasmic reticulum, plasma membrane, cytosol, and cell wall and thus, as multicomposite structures that are embedded in the cell wall, they are notoriously difficult to isolate from whole plant ...

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.

In the past20 years, improved methods of preservation, microscopy, and data analysis have lead to increased understanding of the ultrastructure of the plasmodesmata of flowering plants. Features such as proteinaceous particles, spokes, and cell wall specializations have been described.
