Abstract
Porphyridium purpureum (Bory) Drew et Ross (Syn.: P. cruentum Nägeli) is a classical laboratory organism and one of the few red algae easily grown in large quantities. This would make it an obvious candidate for investigation of red algal mitosis with the electron microscope. The nuclei are, however, quite small and fast dividing, so that previous attempts remained apparently unsuccessful1,2 and left the much more complex species Membranoptera platyphylla the only red alga where mitosis had been satisfactorily described3. We are now able to report that mitosis in Porphyridium is not only quite distinct from that in Membranoptera but also presents an unique association of microbodies with the spindle poles.
