Keiko Sugimoto, Regina Himmelspach, Richard E. Williamson, and Geoffrey O. Wasteneys. (2003). Mutation or Drug-Dependent Microtubule Disruption Causes Radial Swelling without Altering Parallel Cellulose Microfibril Deposition in Arabidopsis Root Cells. Plant Cell 15, 1414–1429.
On page 1426, the term “cellulose microfibrils” was mistakenly replaced with “cortical microtubules.” The sentence should read as follows: “Perhaps more importantly, cellulose microfibrils remained transverse to the root's long axis, suggesting that the microfibrils may have passively realigned as a result of root twisting.”
