WebA key question in development is how organs know when to stop growing. Using the Arabidopsis sepal as a model, Hervieux et al. show that growth-derived mechanical stress impacts microtubule orientation at the sepal tip, further restricting growth in that domain. Such a mechanical feedback loop may constitute a general proprioception mechanism.
