Abstract

I summarize my scientific journey from my first interest in science to my career investigating how plants use the phytochrome photoreceptor to regulate what genes they express. I then describe how this work led to an understanding of how circadian rhythms function in plants and to the discovery of CCA1, a component of the plant central oscillator.

摘要

我总结了自己从最初对科学的兴趣到从事研究植物如何利用光敏色素光感受器来调控其所表达基因的职业生涯的科学历程。然后我描述了这项工作如何促成了对植物昼夜节律功能的理解以及植物中央振荡器组件CCA1的发现。
