像许多生物一样,植物进化出了一个遗传网络,即昼夜节律钟,以协调昼夜循环。在植物中,生物钟是发育的普遍调节器,并调节生理学的许多方面。生物钟调控的过程包括从生长和细胞分裂的正确时机到与根部微生物组的相互作用。最近开发的技术,如单细胞延时显微镜和单细胞RNA-seq,开始彻底改变我们对这种时钟调节的理解,揭示了器官,组织和细胞类型特异性的惊人程度。在这篇综述中,我们强调了最近的进展,在我们的空间视图的时钟在整个工厂,无论是在它是如何调节和它如何调节的输出过程的多样性。我们概述了如何理解这些空间特定的功能将有助于揭示的方式,时钟提供了一个健身的植物效益的范围。新兴的工具和技术提供了对生物钟的行为和输出如何在整个工厂中变化的见解。
Like many organisms, plants have evolved a genetic network, the circadian clock, to coordinate processes with day/night cycles. In plants, the clock is a pervasive regulator of development and modulates many aspects of physiology. Clock-regulated processes range from the correct timing of growth and cell division to interactions with the root microbiome. Recently developed techniques, such as single-cell time-lapse microscopy and single-cell RNA-seq, are beginning to revolutionize our understanding of this clock regulation, revealing a surprising degree of organ, tissue, and cell-type specificity. In this review, we highlight recent advances in our spatial view of the clock across the plant, both in terms of how it is regulated and how it regulates a diversity of output processes. We outline how understanding these spatially specific functions will help reveal the range of ways that the clock provides a fitness benefit for the plant. Emerging tools and techniques provide insights into how the behavior and outputs of the circadian clock vary across the plant.
