Abstract

Amiprophos methyl (APM) is a strong, readily reversible and highly selective inhibitor of tubulin synthesis in Chlamydomonas reinhardi. The extensive induction of tubulin synthesis that accompanies flagellar regeneration in this organism is prevented by 3 to 10 micrometerAPM. When applied after induction has begun, APM causes a rapid cessation of tubulin synthesis. Translation studies in vitro indicate that the lack of tubulin production in APM-treated cells is not due to a direct inhibition of tubulin messenger RNA translation but rather to a selective depletion of tubulin messenger RNA.
