SummaryA model is proposed for the structure of the plasmodesmata ofAzolla root primordia, based on micrographs obtained by a combination of fixation in glutaraldehyde/p-formaldehyde/tannic acid/ferric chloride, digestion of cell walls and the use of stereo pairs. Unlike the model for plasmodesmatal structure proposed byRobards (1971), the desmotubule is depicted as a virtually closed cylindrical bilayer providing little or no open pathway for transport. In this respect it is similar to the…

Fine structure of plasmodesmata in mature leaves of sugarcane
TLDR
The results indicate that the fine structure of plasmodesmata in sugarcane differs among various cell combinations in a cell-specific manner, but that three basic structural variations can be recognized among plasmODEsata in the mature leaf.
Plasmodesmata and the problems with size: interpreting the confusion.
Plasmodesmata and the control of symplastic transport
TLDR
Plasmodesmata are now thought of as fluid, dynamic structures that can be modified both structurally and functionally to cope with the requirements of specific cells and tissues.
The ultrastructure of the plasmodesmata of the salt glands ofTamarix as revealed by transmission and freeze-fracture electron microscopy
TLDR
Observations from both thin sections and freeze-fracture replicas indicate the presence of a circular cluster of six particles around the axial component near the cytoplasmic termini of the plasmodesmata.
Shaping intercellular channels of plasmodesmata: the structure-to-function missing link.
TLDR
This review attempts to reassess the function of the different elements comprising the plasmodesmata and the relevance of membrane lipid composition and biophysics in defining specialized microdomains of PD, critical for their function.
Callose deposition at plasmodesmata
TLDR
The inhibition of callose formation by chemical means showed that the neck constrictions and raised collars in this area are artefacts due to physical wounding and glutaraldehyde fixation.
Substructure of freeze-substituted plasmodesmata
TLDR
The substructure of plasmodesmata in freeze-substituted tissues of developing leaves of the tobacco plant was studied by high resolution electron microscopy and computer image enhancement techniques and the space between the desmotubule and the plasma membrane appears to be the major pathway for intercellular transport through plasmodemata.
Architecture and permeability of post-cytokinesis plasmodesmata lacking cytoplasmic sleeves
TLDR
Surprisingly, the post-cytokinesis plasmodesmata allow diffusion of macromolecules despite the apparent lack of an open cytoplasmic sleeve, forcing the reassessment of the mechanisms that control plant cell–cell communication.
Plasmodesmata as a Modulator of Osmotic Water Fluxes in Plants
Solutions to some key problems in the relationships between the structure and functions of plasmodesmata, a component of the plant intercellular communication system, are proposed on the basis of the…
Rapid detection of plasmodesmata in purified cell walls
TLDR
3,3′-dihexyl-oxacarbocyanine iodide (DiOC6), a cationic amphiphilic fluorescent probe, widely employed for general studies of membrane structure and dynamics is used for the detection of plasmodesmata in isolated cell walls and will prove useful for studies ofplasmodesmal location, structure, and composition.

The neck constriction in plasmodesmata
TLDR
Simple plasmodesmata between mesophyll and bundle sheath cells in actively expanding leaves of Salsola kali L. and roots of Epilobium hirsutum are shown to possess specialized structures, called sphincters, around their neck regions, and evidence is presented that these ring structures are structural equivalents to hypothetical Sphineters performing some valve function.
A new interpretation of plasmodesmatal ultrastructure
TLDR
The plasmalemma, where it lines the plasmodesmatal canal, appears to have particulate subunits in the outer opaque layers and the presence of these subunits may be attributable to the need for stability in membranes arranged about so small a radius.
Plasmodesmata in Higher Plants
TLDR
The first detailed description of “offene Communicationen”, or protoplasmic connecting threads is usually attributed to Tangl (1879), but, despite numerous other suggestions, the word has survived the test of time and is now almost universally accepted.
Observations on structure and differentiation in plasmodesmata
TLDR
Evidence is presented that the young cell wall after division contains a large number of plasmodesmata, probably functionally and structurally identical, and that the development process involves characteristic modifications both to the distribution of plASMata within the wall, and to the structure of individual plasmodemata.
Distribution and structure of the plasmodesmata in mesophyll and bundle-sheath cells of Zea mays L.
TLDR
The movement of photosynthetic intermediates between mesophyll and sheath cells is restricted largely or entirely to the plasmodesmata (symplastic pathway) and transpirational water movement to the cell walls (apoplastic pathway).
Endoplasmic reticulum in the formation of the cell plate and plasmodesmata
TLDR
Electron microscopic observations show that elements of ER become loosely associated with aggregating dictyosome vesicles at the onset of plate formation, and structural observations support the idea that during formation of the plasmodesma a tubular element of ER is tightly furled upon itself and its inner leaflet is compressed into a rod.
The Ultrastructure of Plasmodesmata in Sucking Scale in Tillandsia
TLDR
It is suggested that the endoplasmic reticulum traverses the plasmodesma, constituting the inner structure of Tillandsia usneoides L, which is useful better to understand the activity regulating the passage of substances from one cell to another.
The ultrastructure of plasmodesmata
SummaryIt is suggested that the central strand which traverses plasmodesmata is in open continuity with the endoplasmic reticulum of adjacent cells, and that this strand (desmotubule) represents a…
Intercellular communication inAzolla roots: II. Electrical coupling
TLDR
There is a predictable and well defined variation in numbers of plasmodesmata in roots of Azolla, and some suggestion that plasmodemata may be less resistive towards the apical cell than away from it is given.
Fine structure of the plasmodesm
TLDR
Some new evidence is presented on the cytopla, smic re t icnlum from a cell to its neiahbours is still debatable, and only a few details of the u l t ras t ruc ture .of the p lasmodesms are known.
