 note = {Plasmodesmata are unique channel structures in plants that link the fluid cytoplasm between adjacent cells. Plants have evolved these microchannels to allow trafficking of nutritious substances as well as regulatory factors for intercellular communication. However, tracking the behavior of plasmodesmata in real time is difficult because they are located inside tissues. Hence, a system was constructed to monitor the movement of substances by plasmodesmata using tobacco BY-2 cells, which are linearly organized cells, and a microfluidic device that traps them in place and facilitates observation. After targeting one cell for photobleaching, recovery of the lost H2B-GFP protein was detected within 200 min. No recovery was detected in that time frame by photobleaching the entire cell filaments. This suggested that the recovery of H2B-GFP protein was not due to de novo protein synthesis, but rather to translocation from neighboring cells. The transport of H2B-GFP protein was not observed when sodium chloride, a compound known to cause plasmodesmata closure, was present in the microfluid channel. Thus, using the microfluidic device and BY-2 cells, it was confirmed that the behavior of plasmodesmata could be observed in real time under controllable conditions.},
