Evaluating molecular movement through plasmodesmata
2020Plasmodesmata are membrane-lined cytoplasmic passageways that facilitate the movement of nutrients and various types of molecules between cells in the plant. They are highly dynamic channels, opening or closing in response to physiological and developmental stimuli or environmental challenges such as biotic and abiotic stresses.

Planta, 1997
Functional studies on molecular transport through plasmodesmata in leaf mesophyll and trichome cells revealed significant differences in their basal size-exclusion limits and their response to microinjected tobacco mosaic virus movement protein (E. Waigmann et al., 1994, Proc. Natl. Acad. Sci. USA 91: 1433-1437; E. Waigmann and P.

Plasmodesmata: the battleground against intruders
Trends in Plant Science, 2011Plasmodesmata are intercellular channels that establish a symplastic communication pathway between neighboring cells in plants. Owing to this role, opportunistic microbial pathogens have evolved to exploit plasmodesmata as gateways to spread infection from cell to cell within the plant.

Plasmodesmata - Virus Interaction
1990The initial entry and replication of a virus in a host plant occurs in only a small number of cells. Expression of viral symptoms in the plant is a result of the spreading of competent viral genetic material (either as particles or as unencapsidated RNA/DNA) through the host plant. In nonhost plants, the virus either fails to replicate or replicates in

Plasmodesmata – membrane tunnels with attitude
Current Opinion in Plant Biology, 2011Plasmodesmata are doors in the rigid cell wall. In multicellular tissues, they allow the passage of molecules needed to create physiological gradients and, by closure, symplastic boundaries, which are necessary for the fundamental processes of plant growth, development and defence.

1999
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.

Elongated virus particles in plasmodesmata
Journal of Ultrastructure Research, 1976Numerous particles of tobacco mosaic virus (TMV) were found in plasmodesmata of mesophyll leaf cells of infected Nicotiana tabacum; and of tobacco etch virus (TEV) in infected N. tabacum and Datura stramonium. As in N. tabacum infected with potato virus Y (PVY), the central plasmodesmatal structure, the desmotubule, was often seen, but in the presence ...

Intercellular protein trafficking through plasmodesmata
Plant Molecular Biology, 1998During plant morphogenesis, groups of cells differentiate to form specialized tissues possessing distinct structures and functions. Cell specialization is a result of specific gene expression at the individual cell level. Coordination of differential gene expression among cells requires that cells communicate with one another.

Plasmodesmata: structure, function and biogenesis
Current Opinion in Plant Biology, 2008Plasmodesmata remain one of the outstanding mysteries in plant biology. In providing conduits for the exchange of small and large, informational molecules they are central to the growth, development and defence of all higher plants. In the past few years, strategies have been devised for the molecular dissection of plasmodesmal composition and function,
