Abstract

Tip growth of root hairs and pollen tubes provides an excellent model for the study of plant cell growth since all the critical molecular players and essential signalling pathways operate simultaneously at the tip of the growing cell. Though not all molecular mechanisms are yet fully understood, many factors have been identified that control and integrate the various structural and physiological networks involved and that thus initiate and maintain polar organization and tip growth. Presently, we will focus on membrane trafficking, in particular on the spatio-temporal regulation of endocytosis and selective recycling by vesicle trafficking and its meaning for the regulation of tip growth. The current state of the art allows to in detail comparing tip growth in root hairs and pollen tubes. Data from both systems may be mutually complementary and used for a better understanding of the complex phenomenon of tip growth.
