The amount of plasmodesmata in a leaf is an aspect of a species'anatomy and not necessarily a determinant of phloem-loading strategy.

While the cell plate is growing, segments of smooth endoplasmic reticulum are trapped within it, later forming the plasmodesmata connecting the two daughter cells.

There are two forms of plasmodesmata : primary plasmodesmata, which are formed during cell division, and secondary plasmodesmata, which can form between mature cells.

Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasmodesmata ( channels between the cells ).
37.
The cells often take on the appearance of a pincushion, and the plasmodesmata almost cease to function because they become constricted, a condition known as plasmolysis.
38.
Plants probably have specialized mechanisms for transporting mRNAs through plasmodesmata, and these mechanisms are thought to be used by RNA viruses to spread from one cell to another.
39.
In plants, RNAi is thought to propagate by the transfer of siRNAs between cells through plasmodesmata ( channels in the cell walls that enable communication and transport ).

My grad student sort of likes the plasmodesmata idea; we're now looking at particular movement protein papers to see if anything like this has been attempted before.
