硅藻是极地海洋微生物的一个关键群体，支持着高产的海洋生态系统。像地球上的所有生命一样，硅藻并不是孤立生活的，因此它们处于不断的生物和非生物压力之下，这些压力通过自然选择直接影响它们的进化。尽管它们在极地生态系统中很重要，但与温带物种相比，极地硅藻的研究不足。观察到的极地气候的快速变化，特别是变暖，引起了越来越多的研究兴趣，以发现潜在的原因和对整个生态系统的单一物种的潜在后果。下一代测序（NGS）技术通过揭示对极地环境条件的生理适应的分子基础，极大地扩展了我们的知识。它们的基因组、转录组和蛋白质组以及海洋极地微生物组的第一批真核元组学数据反映了环境压力通过适应性反应，如蛋白质家族随着时间的推移而扩大，作为选择的结果。极地地区及其微生物组与气候周期及其反馈循环有着内在的联系。建立在以硅藻为主要初级生产者的“组学”资源基础上的综合理解将使我们能够揭示极地海洋微生物共同进化和适应的统一概念。这种知识旨在将过去的环境变化与具体的适应措施联系起来，将需要改进极地生态系统的气候预测模型，因为它提供了一个统一的框架，说明相互作用和共同进化的生物群落如何应对未来的环境变化。
Diatoms, a key group of polar marine microbes, support highly productive ocean ecosystems. Like all life on earth, diatoms do not live in isolation, and they are therefore under constant biotic and abiotic pressures which directly influence their evolution through natural selection. Despite their importance in polar ecosystems, polar diatoms are understudied compared to temperate species. The observed rapid change in the polar climate, especially warming, has created increased research interest to discover the underlying causes and potential consequences on single species to entire ecosystems. Next-Generation Sequencing (NGS) technologies have greatly expanded our knowledge by revealing the molecular underpinnings of physiological adaptations to polar environmental conditions. Their genomes, transcriptomes, and proteomes together with the first eukaryotic meta-omics data of surface ocean polar microbiomes reflect the environmental pressures through adaptive responses such as the expansion of protein families over time as a consequence of selection. Polar regions and their microbiomes are inherently connected to climate cycles and their feedback loops. An integrated understanding built on “omics” resources centered around diatoms as key primary producers will enable us to reveal unifying concepts of microbial co-evolution and adaptation in polar oceans. This knowledge, which aims to relate past environmental changes to specific adaptations, will be required to improve climate prediction models for polar ecosystems because it provides a unifying framework of how interacting and co-evolving biological communities might respond to future environmental change.
