Molecules of cellulose synthase, the enzyme that produces cellulose, follow microtubule “tracks” in growing plant cells. Each image in this set consists of 30 frames, taken at 10 second intervals, laid on top of one another to track the motion of fluorescent molecules. Cellulose synthase (green, panel A) and tubulin, the protein that makes up microtubules (red, panel B), are highly correlated, especially in the areas marked with arrows. Very little of either molecule is found inside the area marked with brackets. The third image (panel C) shows both panels superimposed on each other.
