The Cell Biology of Cellulose Synthesis: Video 1

A video from the 2014 review by Heather E. McFarlane, Anett Döring, and Staffan Persson, "The Cell Biology of Cellulose Synthesis," from the Annual Review of Plant Biology.

GFP-CesA3 signal in the plasma membrane of Arabidopsis dark-grown hypocotyl cells. Small particles of GFP-CesA3 signal at the plasma membrane presumably represent cellulose synthase (CesA) complexes (CSCs) that probably include multiple copies of the GFP-tagged CesA3 subunit. These particles move at a constant speed along a linear trajectory as the CSC synthesizes cellulose. Individual particles appear, representing CSC deliveries to the membrane, and other particles eventually disappear from the plasma membrane, implying that the CSC may be recycled after some time. The scale bar represents 10 μm, the time stamp shows minutes:seconds, and the video covers 12.5 min of imaging.
