Land plants have developed highly sophisticated intercellular channels called plasmodesmata (PD) that mediate the cell-to-cell trafficking of signaling molecules, including non-cell autonomous proteins (NCAPs) and RNAs. Until recently, the biological significance of this position-dependent intercellular signaling system was underestimated, as only a limited number of endogenous NCAPs had been discovered. However, identification of an ever-increasing population of NCAPs suggests that the PD… CONTINUE READING
