Photosynthetic Processes and Mechanisms

The pollen tube grows inside the pistil, carrying male gametes to the ovule. During this journey, it invades diverse tissues, sensing and adapting to abrupt transitions in mechanical environment. In this issue of Developmental Cell, Zhou et al. identify a receptor-like kinase/Rho-GTPase module that regulates adaptation to such a transition.
