Exocytosis-coordinated mechanisms for tip growth underlie pollen tube growth guidance
Abstract
Tip-growing cells can find their growing path toward the source of attractive signals. Here, using experimental data and mathematical modeling, Luo et al. demonstrate that tip-localized exocytosis can integrate guidance cues with Rho GTPase signaling to control cell wall mechanics and direct tip growth in Arabidopsis pollen tubes.
