Research Abstract

Cell polarity is fundamental to plant development. However, its precise mechanisms are largely unknown. This study revealed that Arabidopsis NIMA-related kinases regulate the polarity of cell division and elongation via microtubule organization. In addition, we have characterized the mechanism of xylogen transport and the expression pattern of xylogen family.
