Membrane skeleton spectrin in pollen and pollen tube

Immuno-western blots, immunofluorescence and immuno-gold labeling methods were used to study the existence and distribution of a homologue of the membrane skeleton spectrin in the pollen and pollen tube ofLilium davidii Duch. A spectrin homologue was found to exist in the pollen and pollen tube, distributed on membranes of secretory vesicles near Golgi apparatus.
