The activity of plasmodesmata are linked to physiological and developmental processes within plants. There is a hormone signaling pathway that relays primary cellular signals via the plasmodesmata. There are also patterns of environmental, physiological, and developmental cues that show relation to plasmodesmata function.
All of the cellular functions of a sieve-tube element are carried out by the (much smaller) companion cell, a typical nucleate plant cell except the companion cell usually has a larger number of ribosomes and mitochondria. The dense cytoplasm of a companion cell is connected to the sieve-tube element by plasmodesmata. [10]
A desmotubule is an endomembrane derived structure of the plasmodesmata that connects the endoplasmic reticulum of two adjacent plant cells. [1] [2] The desmotubule is not actually a tubule but a compact, cylindrical segment of the ER that is found within the larger tubule structure of the plasmodesmata pore. [3]
In multicellular plants, the structural functions of cell junctions are instead provided for by cell walls. The analogues of communicative cell junctions in plants are called plasmodesmata . Anchoring junctions
While the presence of abundant plasmodesmata does allow for passive, symplastic transport, it does not exclude the possibility of active, apoplastic transport. The amount of plasmodesmata in a leaf is an aspect of a species' anatomy and not necessarily a determinant of phloem-loading strategy. Plants with a polymer-trapping mechanism may have ...
