- Pollen tubes are tubular structures that extend by tip growth. Upon overexpression of merely a single endogenous molecule, LePRK1, or a portion of it lacking its extracellular domain, pollen tube cells switched to an alternative mechanism for extension of the leading edge that is analogous to the blebbing growth mode reported for Dictyostelium and for Drosophila stem cells.
