Actin microfilaments (MFs) are essential for the growth of the pollen tube. Although it is well known that MFs, together with myosin, deliver the vesicles required for cell elongation, it is becoming evident that the polymerization of new actin MFs, in a process that is independent of actomyosin-dep...
