CHE SIGNIFICA SYMPLASTIC IN INGLESE
symplast
La simplast di una pianta è il lato interno della membrana plasmatica in cui l'acqua può diffondersi liberamente. I plasmodesmata permettono il flusso diretto di piccole molecole come gli zuccheri, gli amminoacidi e gli ioni tra le cellule. Molte molecole, tra cui fattori di trascrizione e virus vegetali, possono anche essere trasportati con l'aiuto di strutture actina. Ciò consente il flusso di citoplasma diretto al citoplasma di acqua e di altre sostanze nutritive lungo i gradienti di concentrazione. In particolare, viene utilizzato nei sistemi radici per portare sostanze nutritive dal suolo. Spinge questi soluti dalle cellule epidermiche attraverso la corteccia nell'endodermide e, infine, la pericola, dove può essere spostata nell'acero per il trasporto a lunga distanza. È in contrasto con il flusso apoplastico, che utilizza il trasporto delle pareti cellulari.
definizione di symplastic nel dizionario inglese
La definizione di symplastic nel dizionario è o relativa al sistema continuo di protoplasti, collegati da plasmodesmata e delimitati dalla parete cellulare.

Plant Physiological Ecology
One is through plasmodesmata. This is known as symplastic (or symplasmic)
transport. (The symplast is the internal space of cells, surrounded by plasma
membranes. Since plasmodesmata are lined by the plasma membrane, cells
connected ...

Vascular Transport in Plants
Three pathways can be considered: apoplastic, symplastic, and transcellular. The
apoplast of a group of living parenchyma cells is the continuum of cell walls. The
intermicrofibrillar spaces in the wall through which water and ions can move ...

A symplastic route may be common to both developing organs such as young
leaves, buds or root tips and to maturing sinks such as legume root nodules and
some meristematic tissues. A symplastic pathway would seem to involve less ...

Principles of Plant Nutrition
As in the source, the assimilates move from the phloem through the symplast via
plasmodesmata (symplastic path) or they may follow the apoplast at some point(s
). The apoplastic unloading step represents assimilate flux across the plasma ...

Parasitic Orobanchaceae: Parasitic Mechanisms and Control ...
Two broad categories of phloem loading, symplastic and apoplastic, are
recognized in plants, although gradations exist between these two and some
species may not fall clearly into either camp (Gamalei 1989; Rennie and Turgeon
2009).

Formal Descriptions of Developing Systems
In our approach we treat the symplastic growth of a plant organ as an example of
irreversible deformation (plastic strain). Specificity of the organ in comparison to
elasto-plastic or elasto-viscous solids is expressed mainly in cell divisions.

Handbook of Plant and Crop Physiology
Furthermore, Van Bel [2731 proposed that the type I (symplastic loading)
isevolutionarily primitive and type 2 is evolutionarily advanced. He also pointed
out that type 1 is more prevalent in tropical rain forests, type 2a predominates in
steppe ...

In two South African grasses, characterized by predominantly apoplastic
