NanoSIMS data, 13C assimilation in the symbiotic dinoflagellates and their foraminiferal host (Orbulina universa)

Here we performed pulse-chase experiments with 13C-enriched dissolved inorganic carbon, followed by TEM and quantitative NanoSIMS isotopic imaging to visualize photosynthetic C assimilation by individual symbiotic dinoflagellates and subsequent translocation to their Orbulina universa host.

本研究以富含碳-13（13C）的溶解无机碳开展脉冲追踪实验，随后借助透射电子显微镜（TEM）与定量纳米二次离子质谱（NanoSIMS）同位素成像技术，实现对单个共生甲藻光合碳同化过程的可视化观测，并追踪光合碳向其宿主环球抱球虫（Orbulina universa）的后续转运过程。
