The actin cytoskeleton plays a crucial role in the growth and polarity of the pollen tube. Due to inconsistencies in the conventional preservation methods, we lack a unified view of the organization… Expand
Actin polymerization is important in the control of pollen tube growth. Thus, treatment of pollen tubes with low concentrations of latrunculin B (Lat-B), which inhibits actin polymerization, permits… Expand
Given the importance of the actin cytoskeleton to pollen tube growth, we have attempted to decipher its structure, organization and dynamic changes in living, growing pollen tubes of Nicotiana… Expand
ABSTRACT Although most people think of pollen merely as an allergen, its true biological function is to facilitate sexual reproduction in flowering plants. The angiosperm pollen grain, upon arriving… Expand
Pollen tube growth is fast (~300 nm/sec in lily), highly polarized (tip growth), and oscillatory (100 to 500 nm/sec over a period of 20-50 sec). Many underlying physiological processes and… Expand
