Abstract
The development of germinating Phycomyces spores was not inhibited by 5-fluorouracil (1 mM) until the emergence of the germination tube. Fluorouracil was incorporated into RNA as efficiently as uracil; it did not inhibit the synthesis of proteins and the increase in respiratory activity during early develpment. Cycloheximide inhibited development as well as the increase in respiration and protein synthesis. This suggested that protein synthesis or some other cycloheximide dependent process, but no mRNA synthesis, was needed for the first developmental stages. The activity of two enzymes involved in the synthesis of N-acetylglucosamine increased markedly during germination. This increase was inhibited by both 5-fluorouracil and cycloheximide; this suggested that those enzymes were synthesized on mRNA formed during germination.This publication has 8 references indexed in Scilit:
