From the outside, it seems that plants are not moving around, but on the inside of their cells is a remarkable level of activity. For example, the nucleus of root hair cells, finger-like projections of the root epidermis, moves towards the tip as the cell grows. It has long been assumed that this movement is driven by a myosin motor protein that was previously identified to bind to the nucleus. Research in the Nebenführ lab has now established that this simple model is not correct and that these nuclear movements instead rely on a complex interplay of actin filaments, microtubules, and different motor proteins to position the nucleus properly. This work by two talented undergraduate students, Justin Brueggeman and Ian Windham, has now been published in the Journal of Experimental Botany.
