Abstract
During desiccation of the moss Tortula ruralis (Hedw.) (Gaertn, Meyer and Scherb) polyribosomes are conserved. On rehydration, protein synthesis is rapidly resumed. In the presence of protein synthesis initiation inhibitors ribosome run-off from the conserved polyribosomes takes place, confirming that these retain their activity as intact structures during desiccation.
摘要
在苔藓 Tortula ruralis（Hedw.）（Gaertn、Meyer 和 Scherb）干燥过程中，多核糖体得以保留。在重新水合时，蛋白质合成迅速恢复。在存在蛋白质合成起始抑制剂的情况下，从保留的多核糖体上发生核糖体的脱落，这证实了在干燥过程中这些多核糖体作为完整结构保留其活性。
