RESUMO
Chloramphenicol, an inhibitor of mitochondrial protein synthesis, shortened the period length of the circadian rhythm in the Timex strain of Neurospora crassa by 2 hours. Both the l(+) threo and d(−) threo optical isomers had the same effect on the period of the rhythm, whereas only the d(−) threo isomer significantly inhibited mitochondrial protein synthesis. Tetracycline, another inhibitor of mitochondrial protein synthesis, did not change the period of the circadian rhythm. The effect of chloramphenicol on the circadian rhythm is, therefore, presumably not directly related to inhibition of mitochondrial protein synthesis, suggesting that chloramphenicol has other effects.
