Abstract

Summary: The activity of ornithine decarboxylase (EC 4.1.1.17) and the intracellular pools of putrescine and spermidine were determined during zoospore germination and hormoneinduced sexual morphogenesis in The specific activity of ornithine decarboxylase increased approximately 6-fold during zoospore germination and outgrowth in an enriched medium. Ornithine decarboxylase activity exhibited a rapid and transient 5.2-fold increase during hormone-induced differentiation of mycelium cultured in enriched media. In contrast, the enzyme activity did not increase following hormone treatment of mycelium cultured in a minimal medium, yet mycelial differentiation occurred normally. Fluctuations in intracellular concentrations of putrescine and spermidine, in general, correlated with changes in ornithine decarboxylase activity during hormone-induced differentiation and zoospore germination.
