Unicellular marine cyanobacteria constitute 20-40% of total marine chlorophyll biomass and carbon fixation, and hence significantly impact the global carbon cycle and are very relevant to combating global warming. This research will reveal some of the major mechanisms by which marine cyanobacteria have adapted to metal levels in coastal and oligotrophic environments. Thus these results will help us understand the distribution and diversity of these organisms in relation to global primary productivity. They will also lead to the development of more robust biomarkers for metal stress and pollution in coastal environments.

单细胞海洋蓝细菌占海洋叶绿素生物量和固碳量的20-40%，因此对全球碳循环具有重要影响，与应对全球变暖非常相关。这项研究将揭示海洋蓝藻适应沿海和贫营养环境中金属水平的一些主要机制。因此，这些结果将有助于我们了解这些生物的分布和多样性与全球初级生产力的关系。它们还将导致开发更强大的生物标志物，用于沿海环境中的金属压力和污染。
