Abstract

A 24-hour rhythm of gas exchange has been detected in dry onion seeds. The rhythm persists in constant conditions, and its period appears to be independent of temperature. Since DNA replication, transcription, and perhaps translation do not occur in this quiescent state, it is concluded that the basic oscillation that defines circadian rhythmicity does not derive directly from these processes.

摘要

在干洋葱种子中检测到了24小时的气体交换节律。这种节律在恒定条件下持续存在，其周期似乎与温度无关。由于在这种静止状态下不会发生DNA复制、转录，或许还有翻译，因此可以得出结论，定义昼夜节律性的基本振荡并非直接源于这些过程。
