Abstract: | Large numbers of subprotoplasts were isolated enzymatically from pollen tubes of Antirrhinum majus L. When these subI)rotoplasts, either nucleate or enucleate, were cultured in D2 liquid eulture medium, each formed a thick cell wall and germinated a pollen tube like strueture which also deposited a thick wall, except at the tip of the tube. Tube growth was accomparied by a continuous movement of the mass of cell inelusion in this tube to the tip. Rupture of the naked tip oeeurred within one to six days releasing the mass of cell inelusion in the tube into the culture medium. The faet that both nucleate and enneleate subprotoplasts show the same cultural behavior eharaeteristie of the gene expression of a normal pollen tube demonstrates the presence of presynthesized mRNA in the germinated tubes. |
