Aphidicolin Inhibition of DNA Synthesis and Germination in Spores of Anemia phyllitidis L. Sw.
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.
