MOESM1 of Transcriptomic and proteomic responses to very low CO2 suggest multiple carbon concentrating mechanisms in Nannochloropsis oceanica WeiLi HajjamiMohamed El ShenChen YouWuxin LuYandu LiJing JingXiaoyan HuQiang ZhouWenxu PoetschAnsgar XuJian 2019 Additional file 1: Figure S1. A schematic diagram of the experimental design. Nannochloropsis oceanica cells were firstly grown to logarithmic phase under air enriched with 5% CO2. After adaption to new environment under 5% CO2 for an hour, the cells were then cultured under either 100 pm or 50,000 ppm CO2 concentration. Samples were collected at 0, 3, 6, 12 and 24 h from each condition (three biological replicate columns for each) by syringe for physiological characterization and multi-omics (transcriptome, proteome and metabolome) profiling.
