ABSTRACT
Plant growth and development depend on anisotropic cell expansion. Cell wall yielding provides the driving force for cell expansion, and is regulated in part by the oriented deposition of cellulose microfibrils around the cell. Our current understanding of anisotropic cell expansion combines hypotheses generated by more than 50 years of research. Here, we discuss the evolving views of researchers in the field of cellulose synthesis, and highlight several unresolved questions. Recent results using live-cell imaging have illustrated novel roles for cortical microtubules in cellulose synthesis, and further research using these approaches promises to reveal exciting links between the cytoskeleton, intracellular trafficking, and anisotropic growth.
