Aphidicolin inhibits DNA synthesis and nuclear division in spores of Anemia phyllitidis. In spite of blocked DNA replication, spores germinate under continuous dark conditions, if induced by addition of 5 x 10(-5) grams per milliliter gibberellic acid. Differentiation of aphidicolin-treated prothallia indicate the existence of a prepattern in the dry spore which is realized independent of cell division during early events of spore germination.
