Nicotiana pollen tube extracts were treated with 20 µM-taxol and structures derived from the cytoskeleton were collected and observed in the electron microscope. We have identified three different groups of elements with characteristic size and morphology: wide filaments (WF) probably formed by assembled microtubules, thin filaments (TF) interacting with WF and debrislike material principally associated with TF. SDS-PAGE and Western blot analysis provide some preliminary evidence of the biochemical composition of the taxol-induced structures.

Key words: plant microtubules, pollen tube, Xicotiana
