植物通过将环境因素（如白天长度和温度）与内源性发育程序相结合来控制开花时间。开花时间是一种数量性状，也是基因调控如何精确传递的模型。在这篇综述中，我们揭示了花期控制特别丰富的基于RNA加工的基因调控现象。本文综述了在选择性3′端形成、剪接、RNA输出和miRNA生物发生等保守RNA加工事件中起作用的因素及其对开花时间的影响。同样，我们回顾了新的植物特异性rna结合蛋白被确定为开花时间控制的调节因子。此外，我们还在花期调控通路网络中添加了花期基因前mrna的替代加工信息。最后，我们描述了新的方法来剖析支撑这种控制的机制。
Plants control the time at which they flower by integrating environmental cues such as day length and temperature with an endogenous program of development. Flowering time is a quantitative trait and a model for how precision in gene regulation is delivered. In this review, we reveal that flowering time control is particularly rich in RNA processing-based gene regulatory phenomena. We review those factors which function in conserved RNA processing events like alternative 3′ end formation, splicing, RNA export and miRNA biogenesis and how they affect flowering time. Likewise, we review the novel plant-specific RNA-binding proteins identified as regulators of flowering time control. In addition, we add to the network of flowering time control pathways, information on alternative processing of flowering time gene pre-mRNAs. Finally, we describe new approaches to dissect the mechanisms which underpin this control.
