Abstract：
:In Physarum polycephalum (Myxomycetes) aphidicolin has been found to delay metaphase onset when applied to synchronous plasmodia 3 h before control metaphase. In contrast to the action of temperature shifts, aphidicolin treatment did not delay the initiation of the increase of thymidine kinase synthesis (EC 2.7.1.21, ATP-thymidine 5' phosphotransferase) and the decrease of the synthesis of thymidine kinase occurred normally after completion of mitosis in presence of aphidicolin. The amount of thymidine kinase synthesized was larger for aphidicolin treated plasmodia than in the control due to both a longer period of increased synthesis and a higher maximum rate of synthesis. These results were interpreted by postulating the presence of two regulatory pathways. The first one acting on the increase of the synthesis of thymidine kinase and on mitosis onset was sensitive to temperature shifts from 22 to 32 degrees C. The second one acting on mitosis onset only was sensitive to aphidicolin.
