Abstract

Phytochrome mRNA abundance decreased to 20% of the initial level in etiolated cucumber (Cucumis sativus L.) cotyledons exposed to continuous white light. Unexpectedly, by 12 hours of continuous white light, phytochrome mRNA had reaccumulated to 60% of the control level. High stringency RNA blot analyses suggest that it is the mRNA encoding type I phytochrome that reaccumulates.

摘要

连续的白光照射能使黄化的黄瓜（Cucumis sativus L.）子叶中光敏色素 mRNA 的含量降低到初始水平的 20%。然而令人意外的是，在连续白光照射 12 小时后，光敏色素 mRNA 又重新积累到对照水平的 60%。严格的 RNA 印迹分析表明，重新积累的是编码 I 型光敏色素的 mRNA。
