Abstract
Intercalation of cells is an evolutionarily conserved strategy used for a variety of developmental processes in animals. In this issue of Cell, Fu et al. have uncovered an elaborate Rho GTPase-mediated mechanism by which cytoskeletal-dependent intercalation of Arabidopsis leaf cells is achieved, suggesting that conserved Rho GTPase signaling pathways may similarly regulate tissue morphogenesis in animals and plants.
