The C4 dicarboxylic acid pathway of photosynthetic carbon metabolism is a major elaboration of the photosynthetic carbon reduction cycle (PCR-cycle) which has stimulated a great deal of new research into all levels of carbon metabolism in higher plants in recent years (Hatch and Slack, 1970; ...
The stele and the endodermis is a nexus of cell communication involving the transport of the SHR transcription factor from the stele into the endodermis and the reciprocal transport of miR165/6 from the endodermis to the stele. What is particularly striking about this signaling pathway is that al...
The dye did not show a preferential "pathway" through the uninfected cell rays.doi:10.1016/0038-0717(95)98609-rS.M. BrownK.J. OparkaJ.I. SprentK.B. WalshSoil Biology & BiochemistryBrown S. M., Oparka K. J., Sprent J. I., Walsh K. B. (1995). Symplastic transport in soybean...
By contrast, the plasmodesmata in the distal periclinical wall of the stalk cell provide a low resistance pathway for a bulk flow of sugar solution. The desmotubules of the plasmodesmata are clearly connected to the endoplasmic reticulum of the adjacent cells. The cytoplasmic annulus between the ...
Data presented in this paper show that plasmodesmograms offer a means to visualise the potential transport pathway from mesophyll cells to sieve tubes. Furthermore, the results allow an instant appreciation of symplastic continuity or discontinuity and, accordingly, the potential symplastic and-or ...
The transport pathway within the tumor and the mechanism of phloem unloading were investigated by iontophoretic injection of Lucifer yellow CH into sieve tubes. Apparent symplastic solute unloading into parenchyma cells was confirmed by localizing common primary pit fields by staining them with aniline ...
The inverse expression pattern of sucrose transporters, cell wall acid invertase, and soluble acid invertase in these corresponding organs supported the presence of a symplastic sucrose unloading pathway. The transcription profile of genes involved in symplastic unloading and their significantly positive ...
The apoplastic tracers Cellufluor and lanthanum nitrate, and the symplastic tracer uranin, were used to study pathways for transport in leaves and roots of the seagrass Halodule uninervis (Forssk.) Aschers. An apoplastic pathway was shown to exist in most leaf tissues except in the region of ...
(3) The plasmodesmata constitute the pathway of least resistance for the diffusion of all small solutes. (4) Diffusion will be the predominant mechanism of transport across the pores for small solutes. (5) Solute distribution within the bulk cytoplasm of each cell ought to be by a combination...
