Abstract
Synchrony of duplication cycles in Allomyces macrogynus was maintained through five cycles to the end
of vegetative growth. In a culture in which hyphal emergence was inhibited the fourth cycle was abnormal.
No DNA synthesis occurred before septation when zoosporangia developed in culture medium.
When organisms were induced to make sporangia by transfer to water there was a small apparent
increase in DNA prior to but not after septation. The unavoidable extraction of wall glycopeptide poses
some problems in nucleic acid assays. Partial inhibition by 10�M benomyl allowed continued growth
with large rhizoids at every apex. Partial inhibition by mitomycin allowed continued growth without
any further morphological differentiation.
