Pollen tube growth is an essential aspect of plant reproduction because it is the mechanism through which non-motile sperm cells are delivered to ovules thus allowing fertilization to occur. A pollen tube is a single cell that only grows at the tip, and this tip growth depends on actin filaments. Plants encode class VIII and class XI myosins as actin-based motor proteins, of which class XI myosins are required for cell expansion in vegetative tissues.
In Arabidopsis thaliana, 6 of 13 myosin XI genes are expressed in pollen: XIA, XIB, XIC, XID, XIE, and …
