The aim of this review is to examine the role of plasmodesmata in
plant cell communication and molecular trafficking. Plants cannot move from one
place to another, i.e., sessile, but they are continuously facing challenges
from the changing environment to survive and also to fight different pathogens.
This special characteristic is performed by a plant cell through its cell
communication mechanism. Thus cell to cell-to-cell communication mechanism is
essential to understand the way of transferring signals from one cell to
another for performing important metabolic functions. The cell-to-cell
communication process is helping in coordinating growth, differentiation and
development by sending signals from one cell to another. The main function of
communication in plant cells is done through plasmodesmata, which have been
discussed. But recently it has been noted that there is another alternative
mechanism for sending signals, like other eukaryotic cells is through
RNA-binding proteins. There was an idea that plasmodesmata could not allow
large molecules as water and micronutrients, are pass through it. But it has
been noted that its size is not constant but is very dynamic, where its size
can change according to its needs. The role of plasmodesmata and RNA-binding
proteins in communication, as well as molecular trafficking, has been
discussed.
