The REN4 rheostat dynamically coordinates the apical and lateral domains of Arabidopsis pollen tubes
Polar growth of pollen tubes is established by polar localization of ROP1 GTPase activity at the apical tip. Here, Li et al. identify REN4 as a ROP1 interaction partner that restrains the ROP1 distribution to the apex by promoting ROP1 endocytosis from lateral domains of the pollen tube membrane.
