Figure 1 Structural Regulation of Pollen Tube Growth. A summary diagram shows the brief intracellular organization of a growing pollen tube, including actin cytoskeleton, exocytosis, endocytosis, and cell wall dynamics. CCV, clathrin-coated vesicle; EE, early endosome; LE, late endosome; RE, recycling endosome. For details, see the text.

Figure 2 Simplified Model of the Discussed Mechanical Signaling Networks in Self-Organizing Pollen Tube Growth. For better-elucidated signaling modules, feedback regulations and pathway crosstalks are common. Their regulations of structural networks are partially revealed, whilst still needing further characterization. The role of emerging new pathways, such as hormone and small peptide signaling, remains elusive. For details, see the text.
