Figure 1 Plant cells are surrounded by a cell wall made up of cellulose fibrils, and these fibrils are synthesized by a large multisubunit complex that is embedded in the plasma membrane. Paredez et al. (p. 1491, published online 20 April; see the Perspective by Lloyd) visualized the activity of this enzyme, cellulose synthase, in living plant cells using fluorescent tags. Movies show the cellulose synthases moving along trajectories defined by microtubules. The organization of the microtubules directs the organization of the growing cellulose fibrils which, in turn, may govern the shape of the growing cell.
