Book Description
A central question in plant biology is how plants acquire various shapes and sizes. Plant shape depends upon how individual cells grow and divide. Due to its semi-rigid structure, the cell wall plays a huge role in directing cell growth and restraining turgor pressure, thus influencing cell shape and size. The cell wall contains cellulose microfibrils that have been hypothesized to require microtubules as a guiding template for their deposition outside the cell wall. It has been demonstrated that plant cortical microtubules can organize into several array patterns. How the microtubule arrays organize in plant cells is an open question. More specifically, the molecular mechanism governing what physically organizes the microtubule array patterns remains unknown. In an innovative genetic screen, I have discovered a variety of mutants that have axial growth phenotypes that are potentially linked to specific microtubule array defects.
