The cell's "skeleton" is made up in part by thin structures called microtubules that provide structural support and tracks for cargo to be delivered throughout the cell. Microtubules have lives of their own - they are "born" at nucleation sites, grow as tubulin heterodimers are added, and eventually depolymerize as they age. We are interested in studying the molecular mechanisms that govern microtubule dynamics and organization in different types of plant cells.
