Phaseolus coccineus was exposed to valinomycin via the transpiration stream for 5-hr periods. The treatment started at various phases of the free-running circadian rhythm in continuous light; it resulted in phase shifts that varied in a manner dependent on the affected phases. The response curves are similar to those for transient withdrawal of water and for light pulses. The results support the hypothesis that membrane processes are important pacemakers in circadian rhythms.
多花菜豆通过蒸腾流暴露于缬氨霉素中5小时。处理在持续光照下自由运行的昼夜节律的不同阶段开始;这导致了相位偏移,其变化方式取决于受影响的阶段。响应曲线与短暂断水和光脉冲的响应曲线相似。结果支持了膜过程是昼夜节律中重要起搏器的假说。
