The daily cycle of solar radiation has a profound influence in structuring the physiology of microbes in the euphotic zone and subsequently setting the degree of coupling across trophic levels within ocean ecosystems. There has been an upsurge of interest in the biological role of the diel cycle and the ability to probe it using molecular approaches (i.e., “omics”), which now allow us to pinpoint the level of detail of the diel cycle that is required to better understand microbes' roles across multiple biogeochemical cycles. Although sampling the diel cycle requires additional resources, the payback is large. A better understanding of the diel cycle provides a holistic framework with which to align patterns and causal sequences across multi‐omic layers, yielding consequent connections with metabolic processes to develop more robust mechanistic models. Such models provide the stepping stones to better understand how resource allocation in cells is driven by environmental forcing.

利用海洋微生物的 diel 循环更好地了解它们的生物地球化学功能

太阳辐射的每日周期对构建真光区微生物的生理学以及随后确定海洋生态系统中营养级之间的耦合程度具有深远的影响。人们对 diel 循环的生物学作用以及使用分子方法（即“组学”）探测它的能力产生了浓厚的兴趣，现在这使我们能够确定 diel 循环的细节水平，这是更好地了解微生物在多个生物地球化学循环中的作用所需的。尽管对 diel 循环进行采样需要额外的资源，但回报很大。对 diel 循环的更好理解提供了一个整体框架，通过该框架可以跨多组学层调整模式和因果序列，从而与代谢过程产生联系，以开发更强大的机制模型。此类模型为更好地了解细胞中的资源分配如何由环境强迫驱动提供了垫脚石。
