Journal of Cell Science, 2018 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 ...

An RNA exosome subunit mediates cell-to-cell trafficking of a homeobox mRNA via plasmodesmata
Science, 2022Description mRNA migration through plasmodesmata In plants, certain transcription factors are produced in one cell but transported, sometimes as messenger RNA (mRNA), through plasmodesmata, channels between neighboring plant cells, where they act.

Cell-to-cell movement of plant viruses via plasmodesmata: a current perspective on potyviruses.
Current Opinion in Virology, 2021Plant viruses have evolved efficient mechanisms to move cell-to-cell through plasmodesmata (PD) for systemic infection. Potyviruses including many economically important viruses constitute the largest group of known plant-infecting RNA viruses. Potyviral

Arabinogalactan protein polysaccharide chains are required for normal biogenesis of plasmodesmata.
The Plant Journal, 2022Arabinogalactan proteins (AGPs) are a plant-specific family of extracellular proteoglycans characterized by large and complex galactose-rich polysaccharide chains.

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 ...

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 ...

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 (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 ...

Current opinion in plant biology, 2020
Plasmodesmata allow movement of metabolites and signaling molecules between plant cells and are, therefore, critical players in plant development and physiology, and in responding to environmental signals and stresses.

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
