EMBO J (2013) 32: 511–523 doi:; DOI: 10.1038/emboj.2012.330; published online December 14 2012 In plants, the circadian clock is known to regulate a wide variety of processes and it is clear that the clock-conferred ability of plants to anticipate daily changes in environmental conditions confers significant fitness advantages. Two new studies highlight complex reciprocal interactions between the clock and chloroplast iron status and provide significant new insight into the role of iron in control of circadian period length.
在植物中,生物钟被认为调节着各种各样的过程,而且很明显,生物钟使植物能够预测环境条件的日常变化,从而赋予其显著的适应优势。两项新的研究强调了生物钟和叶绿体铁状态之间复杂的相互作用,并为铁在控制生物钟周期长度方面的作用提供了新的重要见解。
