在2012年3月出版的《植物细胞》中，我们描述了拟南芥生物钟基因的广泛选择性剪接（AS）。值得注意的是，这些不同的转录后事件与不同的稳态温度，也与植物经历的温度转换，使我们提出，温度相关的AS是一个额外的机制参与植物昼夜节律钟的操作和控制。在这里，我们表明，温度相关的AS也延伸到REVEILLE 8（RVE 8），证明了一个迄今未被认识到的这种时钟相关基因的表达和温度之间的联系。最后，我们讨论了我们的观察时钟基因表达的塑料性质在转录后水平的背景下，植物如何响应温度的持续魅力。
In the March 2012 issue of The Plant Cell we describe extensive alternative splicing (AS) of Arabidopsis circadian clock genes. Notably these distinct post-transcriptional events associate with different steady-state temperatures and also with plants undergoing temperature transitions leading us to propose that temperature-associated AS is an additional mechanism involved in the operation and control of the plant circadian clock. Here we show that temperature associated AS also extends to REVEILLE 8 (RVE8), demonstrating a hitherto unrecognized link between the expression of this clock associated gene and temperature. Finally we discuss our observations of the plastic nature of clock gene expression at the post-transcriptional level in the context of the ongoing fascination of how plants respond to temperature.
