Abstract: Microtubules are the components of the cytoskeleton in all eukaryotic cells . They are essential for a wide varieties of cellular functions . Most of our knowledge of biochemistry and pharmacology of tubulin has come from extensive studies on mammalian brain microtubule systems, very little information exists on the biochemical and pharmacological properties of plant tubulin and microtubules . We developed an efficient method to prepare enough tubulin in high purity from day lily ( Hemerocallis fulva L .) pollen . Here we reported the ultrastructural morphology of microtubule polymerzied by induction of tubulin taxol in the presence of Mg²⁺ and GTP with transmission electron microscopy .

Key words: Hemerocallis fulva
