| Abstract |
Plant cells have a variety of shapes crucial for their functions, yet the mechanisms that generate these shapes are poorly understood. Genetic dissection of the trichome (plant hair) branching pathway in Arabidopsis, has uncovered mechanisms and identified genes that control plant cell morphogenesis. The recent identification of one of these genes, ZWICHEL (ZWI), as a novel member of the kinesin superfamily of microtubule motors provides a starting point for the analysis of the plant cytoskeleton's role in a specific morphogenetic event.
