Unbudded singlets from exponentially growing yeast cells of Sporothrix schenckii were harvested, selected by filtration and allowed to form germ tubes in a basal medium with glucose at pH 4.0 and 25 degrees C. These conditions supported only the development of the mycelial form of S. schenckii in a reproducible manner which allowed further analysis of the early cellular events occurring during the yeast-to-mycelium transition. The relationship between macromolecular synthesis (DNA and RNA synthesis) and nuclear division, hyphal growth and septum formation were investigated during germ tube formation. RNA synthesis started 0 to 3 h after the induction of germ tube formation, followed by DNA synthesis and the first nuclear division, which took place between 3 and 6 h. Germ tube formation followed nuclear division and was first evidenced 6 h after the induction of germ tube formation, but was not completed until 12 h after inoculation. Septation was first observed in these germ tubes at the mother cell-germ tube junction 6 h after induction. Addition of hydroxyurea, an inhibitor of DNA synthesis, to the medium, also inhibited nuclear division and germ tube growth, suggesting that these processes in S. schenckii are dependent upon DNA synthesis.
