Structure of the Pollen Tube and the Mechanism of Tip Growth
花粉管细胞结构与生长机制研究进展

The pollen tube is the polarized tip-growing system that involves a complicated kinetic process essential for sexual reproduction in higher plants. The process of pollen tube growth involves many aspects, especially the dynamics of the cytoskeleton and cytoplasmic movement. The present paper reviews the structure of the pollen tube, cytoskeleton, and vesicles, as well as mitochondria trafficking and vesicle recycling in pollen tubes.
