摘要：

We have compared the effects of cycloheximide (CHI) and two other rapid and effective inhibitors of protein synthesis, pactamycin and 2-(4-methyl-2,6-dinitroanilino)-N-methyl proprionamide (MDMP), on protein synthesis, respiration, auxin-induced growth and H+-excreation of Avena sativa L. coleoptiles. All three compounds inhibit protein synthesis without affecting respiration. The effectiveness of the inhibitors against H+-excretion and growth correlates with their ability to inhibit protein synthesis. Both CHI and MDMP inhibit auxin-induced H+-excretion after a latent period of 5-8 min, and inhibit growth after a 8-10-min lag. These results support the idea that continued protein synthesis is required in the initial stages of the growth-promoting action of auxin. © 1979 Springer-Verlag.
